LAMBDA – A Serverless Musical

Join the Serverless Revolution!

Learning a new paradigm can be really difficult, especially something as revolutionary (and different) as serverless. Thanks to a little inspiration from fellow AWS Serverless Hero, Forrest Brazeal, I created this Hamilton parody to help teach people what serverless is all about and why it’s such an amazing way to build applications. Hopefully it inspires you as well. Enjoy!

Announcing the Serverless Reference Architectures Project

Serverless gives us the power to focus on delivering value to our customers without worrying about the maintenance and operations of the underlying compute resources. Cloud providers (like AWS), also give us a huge number of managed services that we can stitch together to create incredibly powerful, and massively scalable serverless microservices.

Almost 2 years ago now, I wrote a post on Serverless Microservice Patterns for AWS that became a popular reference for newbies and serverless veterans alike. The capabilities of serverless have changed dramatically since then, opening up a ton of new patterns and possibilities. Today I’m announcing the Serverless Reference Architectures Project. This project is intended to capture, share, explore, and debate the patterns and practices being used in serverless production applications today.

Takeaways from Programming AWS Lambda by Mike Roberts and John Chapin

Recently, Symphonia co-founders Mike Roberts and John Chapin wrote a book called Programming AWS Lambda: Build and Deploy Serverless Applications with Java. I personally abandoned Java long ago, but I knew full well that anything written by Mike and John was sure to be great. So despite the title (and my past war stories of working with Java), I picked up the book and gave it a read. I discovered that it’s not really a book about Java, but a book about building serverless applications with the examples in Java. Sure, there are a few very Java specific things (which every Java developer probably needs to read), but overall, this book offers some great insight into serverless from two experts in the field.

I had the chance to catch up with Mike on a recent episode of Serverless Chats. We discussed the book, how John and Mike got started with serverless (by building Java Lambda functions, of course), and what are some of the best practices people need to think about when building serverless applications. It was a great conversation (which you can watch/listen to here), but it was also jam packed with information, so I thought I’d highlight some of the important takeaways.

Making the Case for Serverless Use Cases

For quite some time, there was a running joke that “serverless” was just for converting images to thumbnails. That’s still a great use case for serverless, of course, but since AWS released Lambda in 2014, serverless has definitely come a long way. Even still, newcomers to the space often don’t realize just how many use cases there are for serverless. I spoke with Gareth McCumskey, a Solutions Architect at Serverless Inc, on a recent two part episode (part 1 and part 2) of Serverless Chats, and we discussed nine very applicable use cases that I thought I’d share with you here.

12 Important Lessons from The DynamoDB Book

Fellow serverless advocate, and AWS Data Hero, Alex DeBrie, recently released The DynamoDB Book, which ventures way beyond the basics of DynamoDB, but still offers an approachable and useful resource for developers of any experience level. I had the opportunity to read the book and then speak with Alex about it on Serverless Chats. We discussed several really important lessons from the book that every DynamoDB practitioner needs to know. Here are twelve of my favorites, in no particular order.

Takeaways from the State of Serverless Report

On a recent episode of Serverless Chats, I spoke with Stephen Pinkerton and Darcy Rayner of Datadog to dig into The State of Serverless report, which was released at the end of February 2020. After frequently fielding customer questions about the topic, Datadog looked at its data and customer use cases, and examined how they were using serverless. Datadog’s report is a way to break it all down, but it’s also an opportunity for its customers (and serverless users alike) to see how other people are using serverless in a data-driven way. I discussed methodology, findings, and key takeaways with Stephen and Darcy, and thought it’d be worthwhile to consolidate and share that insight.

Verifying self-signed JSON Web Tokens (JWTs) with AWS HTTP APIs

“Trust no one.” Or at least that’s what Fox Mulder told me back in the 90s.

With the recent GA of HTTP APIs for API Gateway, I decided to start evaluating my existing API Gateway REST APIs to see if I could migrate them over to take advantage of the decreased latency and reduced cost of the new HTTP APIs. Several of them were disqualified because they utilize service integrations (a feature that AWS is working to add), but for one of my largest applications, the lack of Custom Authorizers is what brought me to a dead end. Or so I initially thought. 😉

After a bit of research (okay, it was actually several hours because I decided to read through a bunch of specs and blog posts and then run a ton of experiments), it turns out that hosting your own OIDC Conformant “server” to verify self-signed JSON Web Tokens with HTTP APIs is actually quite simple. So as long as you can use JWT for your bearer tokens, you can utilize your existing authentication service (and probably dramatically reduce your latency and cost).

In this post, I’ll show you everything you need to know to set this up yourself. We’ll generate certificates, create our OIDC discovery service, set up our HTTP API authorizers, generate and sign our JWTs, and protect routes with scopes.

Takeaways from AWS re:Invent 2019’s Amazon DynamoDB Deep Dive: Advanced Design Patterns (DAT403)

AWS re:Invent 2019 is a wrap, but now the real work begins! There are hundreds of session videos now available on YouTube. So when you have a few days (or weeks) of downtime, you can dig in to these amazing talks and learn about whatever AWS topics you fancy.

I was only able to attend a few talks this year, but one that I knew I couldn’t miss in person, was Rick Houlihan’s DAT403: Amazon DynamoDB deep dive: Advanced design patterns. At the last two re:Invents, he gave similar talks that explored how to use single-table designs in DynamoDB… and they blew my mind! 🤯 These videos were so mind-bending, that they inspired me to immerse myself in NoSQL design and write my How to switch from RDBMS to DynamoDB in 20 easy steps post. I was hoping to have a similar experience with this year’s edition, and I WAS NOT DISAPPOINTED.

As expected, it was a 60 minute firehose of #NoSQL knowledge bombs. There was A LOT to take away from this, so after the session, I wrote a Twitter thread that included some really interesting lessons that stuck out to me. The video has been posted, so definitely watch it (maybe like 10 times 🤷‍♂️), and use it to get started (or continue on) your DynamoDB journey.

Serverless Microservice Patterns for AWS

UPDATE: I’ve started the Serverless Reference Architectures Project that provides additional context and interactive architectures for some of theses patterns along with code examples to deploy them to AWS. Check it out.


I’m a huge fan of building microservices with serverless systems. Serverless gives us the power to focus on just the code and our data without worrying about the maintenance and configuration of the underlying compute resources. Cloud providers (like AWS), also give us a huge number of managed services that we can stitch together to create incredibly powerful, and massively scalable serverless microservices.

I’ve read a lot of posts that mention serverless microservices, but they often don’t go into much detail. I feel like that can leave people confused and make it harder for them to implement their own solutions. Since I work with serverless microservices all the time, I figured I’d compile a list of design patterns and how to implement them in AWS. I came up with 19 of them, though I’m sure there are plenty more.

In this post we’ll look at all 19 in detail so that you can use them as templates to start designing your own serverless microservices.

Off-by-none: Issue #103

Why buy the cow if you get the Machine Learning for free? 🐮

Welcome to Issue #103 of Off-by-none. Thanks for joining us!

Last week, we got some awesome insights into serverless and cloud security and took a look at serverless machine learning. This week, we learn why you don’t need to buy a cow to do machine learning, how serverless can speed up your regression tests and we get a full season of Sessions with SAM to binge watch. Plus, we have plenty of great serverless content from the community.

Before we begin, make sure you check out TriggerMesh. They let you connect all your key SaaS and on-premises apps with AWS EventBridge. And you can also trigger workloads running on any managed Kubernetes cloud. Join the Beta program for Free! Sponsored

When you’re looking for serverless success stories… 📖

“Some of the integrations that weren’t useful anymore, remained in production as nobody was sure if they will break something else by removing it.” If that sounds like an old app you’re working with, see how Marin Radjenovic migrated a legacy application to serverless with EventBridge.

And if that’s not exciting enough for you, check out this post by Fernando Devegili that details how his team used serverless to reduce the amount of time it took to do visual regression tests from 20 minutes to 10 seconds.

When you’re looking for some good serverless use cases… 🗺

Why worry about writing an entire backend when you can just send e-mails right from Cloudflare Workers? Or if you’d like to create an SVG graph from your SQLite database, Alejandro Oviedo will show you how to do it using a Lambda function.

Jerry Mullis shows us how to stop EC2 instances on a scheduled basis, one of those classic serverless DevOps use cases. But if you want to get really meta, how about using serverless to manage its own scalability by scheduling AWS Lambda Provisioned Concurrency?

When there’s more to learn about serverless… 👩‍🏫

Paul Swail answers “where does Fargate fit into your serverless toolkit?” (just in case you had that question too), Yan Cui gives us some tips for debugging AWS Lambda timeouts, and Serkan Özal gives you the pros and cons of using a mono- or multi-repo in a serverless world.

There’s an entire series on running Ruby on AWS Lambda from the team at Hint Media, Ernesto Marquez explains when you should use Amazon RDS vs. Aurora Serverless, and Aman Sharma shares an introduction to Serverless/Edge scripting.

If you want to go back to basics, Shane Lee gives a brief 10-point guide to AWS Lambda. And if you’d like to explore more complex concepts, like static IPs for AWS Lambdas, Austin McDaniel has some ideas for you.

No time to write tests? Jan Groth has  12 recommendations on unit-testing AWS Lambdas in Python. There’s some good advice in here, like not bothering to test boto or other frameworks. They’re probably already well tested, so you should focus on your own business logic.

James Beswick has a new series that will tell you why using serverless backends to iterate quickly on web apps is important to rapid development and deployments, and Yan Cui has another great post that explains what alerts you should have for your serverless applications. Once you figure that out, James Allardice will demonstrate the process of setting up CloudWatch alarms with serverless.

When you just want to build something… 👷‍♀️

Auto-instrumented, trace-centric observability for serverless & k8s
If you’re running distributed serverless, Kubernetes, or containerized environments, you need a specialized tool that’s built to monitor them. Epsagon enables teams to automatically detect, troubleshoot, and resolve issues within complex microservices with no training, manual coding, tagging or maintenance required. Try free today, connect your first trace instantly, and grab one of our “cloud observability” drones! Sponsored

If you’re using Flutter to build native apps and you need a serverless backend, check out this post on full-stack Flutter that’ll show you how to create a backend for your app using AWS & serverless.

Just need to deploy a static site? Abhishek Wagh shows you how to deploy your websites with AWS Amplify (no, not the framework, the console). While you can deploy backends with the Amplify Console as well, Netlify has a pretty slick setup. You may want to check out this introduction to serverless functions.

Ben Smith isn’t ready to quit on the whole serverless PHP thing, so he wrote a post introducing the CDK construct library for the serverless LAMP stack. Regardless of your runtime of choice, implementing a passwordless API using Cognito and the Serverless framework might be a cool addition to your serverless apps.

What to do to tighten up your serverless security… 🔒

Another take on the recent ESG study points out that half of DevOps teams surveyed pushed vulnerable code “because the vulnerabilities identified were discovered too late in the [development] cycle to resolve them in time.” Um, I know lots of us face a tremendous amount of pressure to ship stuff, but knowingly shipping vulnerable code should be a show stopper.

Another interesting post I read was about the dangers of Denial-of-Wallet attacks. I think the possibilities of DoW attacks are very real and that you should absolutely put in place mitigation strategies in order to deal with them if they occur. That being said, I haven’t heard any major horror stories about this other than from devs accidentally doing it to themselves. I’m not saying this won’t be a thing, I just haven’t seen it yet.

When you’re looking for some interesting reading… 🤓

Charity Majors has a great post called The Future of Ops Jobs. In it she explains how Ops are not going away, but morphing into something different than you may be used to. Lots of great advice in here for those Ops people looking to advance their careers.

Remember when people were saying that serverless was a spectrum? Well Gillian Armstrong says that Machine Learning is spectrum and explains how to cheat at it by not owning a cow. There’s a helpful parable in here, but all you really need to know is that buying butter isn’t cheating. 😉

Not sure I’d read this to my kids, but Mariliis Retter wrote a “techy bedtime story” explaining how serverless came to be; complete with wizards, caves, and server monsters. In other serverless analogies, Shrikant Navelkar explains why serverless is like good portion control and helps us overcome the sunk cost fallacy.

When your Netflix Watch List is empty… 🍿

On Episode #62 of the Serverless Chats podcast, I had a chat with Nica Fee about the recently released New Relic One Platform, how observability can both reduce MTTR and help us optimize our applications for happier customers, and how New Relic is embracing open source and making observability available to teams of all sizes. Watch this episode on YouTube!

Yan Cui had an awesome conversation with Zack Kanter from Stedi on Real World Serverless, Episode #24. There’s a great discussion in here about tenancy and how Stedi thinks about it.

And if you’re looking for something to binge watch, all the episodes from Season one of Sessions with SAM starring Eric Johnson are nicely curated in this convenient blog post.

When you realize that apparently the devs at AWS never sleep… ☕️

There was a lot happening this past week at AWS. Let’s see if we can give you a quick summary of some of the major points. First of all Quantum computing is now available on AWS through Amazon Braket. I know it has nothing to do with serverless, but Jeff Barr is really excited about it.

ElastiCache also had a big week, announcing support for resource-based permission policies and ElastiCache Redis now supporting up to 500 Nodes per cluster. And not to be outdone, Amazon DynamoDB Accelerator (DAX) now supports next-generation, memory-optimized Amazon EC2 R5 nodes.

Moving on to more serverless related announcements, AWS is EOLing  Amazon Linux 1 support in Lambda on December 30, 2020. Eric Johnson shows you how you should be migrating AWS Lambda functions to Amazon Linux 2 (note that this means updating your runtimes). In related news, AWS Lambda now supports custom runtimes on Amazon Linux 2 as well as support for Go on Amazon Linux 2.  Plus AWS Lambda now supports Java 8 (Corretto), if you’re into that sort of thing.

In slightly more exciting news, AWS Lambda now supports Amazon Managed Streaming for Apache Kafka as an event source, which James Beswick explains how to set it up here.

AWS Step Functions added support for string manipulation, new comparison operators, and improved output processing, giving customer more flexibility within their state machine definitions and allowing for more dynamic behavior. This post goes into more detail and shows you some of the cool new things you can do.

Amplify iOS v1.1 was released, which includes support for the Combine framework for Swift, Amazon Comprehend added five new languages to Custom Entity Recognition, and Amazon Cognito User Pools now support customization of token expiration.

You can also set up CloudWatch Application Insights using CloudFormation, use the Copy API with Amazon S3 Access Points, and check out the updated Serverless Bot Framework solution that added support for securely integrating with third-party APIs.

When you need some handy serverless tools… 🛠

Any good builder needs their trusty tool belt, and if you’re building with serverless, sls-dev-tools gives you much of what you need. Ben Ellerby outlines some of the most useful features.

Ran Isenberg wrote up a piece on how to do AWS Lambda Event Validation using a tool called Pydantic. If you’re writing functions in python, this could be worth checking out.

Thoughts from Twitter 🐦

“I will die on this hill: One application environment per AWS account.” ~ Tom McLaughlin
As Tom is from Boston, I’ll assume he means Bunker Hill. Regardless, one application environment per account should be the absolute minimum. I heard AWS does one account PER MICROSERVICE. Think about that! 🤔

Serverless security strategies… 🔐

Welcome to Issue #102 of Off-by-none. I’m happy you’re here!

Last week, we shared some dissenting opinions on serverless, but also got a bunch of awesome new tools. This week, we have some awesome insights into serverless and cloud security, we take a look at serverless machine learning, and try something a little different with the newsletter format. Plus, we have lots of great serverless content for you to explore.

When you’re curious what’s new with serverless… 📣

Check out the TriggerMesh guide “What Every CIO Needs to Know about Serverless” for feature comparisons of major offerings and an introduction to basic concepts like cloud native and microservices. Use it to inform your peers / managers on serverless benefits and available options. Sponsored

The Dashbird has a busy week. Not only did they just turn 3 years old, they also introduced Dashbird Atlas, a new real-time 3D map view of your entire serverless environment. And if that’s not enough, they also added insights for AWS Kinesis and Step Functions.

In other, sort of serverless news, WayScript just raised $5 Million. Last week we mentioned Paragon, which seems quite similar. Sort of like IFTTT, but with a lot more flexibility and customizations. I have a feeling we’ll see more and more systems like this that’ll continue to build higher level abstractions on top of serverless infrastructure.

When everyone starts adding buzzwords back into their pitch decks… 📈

Machine Learning is all the rage nowadays, and unlike several years ago when ML/AI was the cornerstone of every investor presentation, lots of companies are now actually able to deliver on that promise. An oft repeated criticism of Lambda (and most FaaS in general) has been its inability to handle machine learning use cases. But thanks to the recent addition of EFS support, and a clever post by Shitij Mathur, setting up serverless machine learning inference with AWS Lambda couldn’t be easier. 😉

There are plenty more examples, include Mike Palei’s post that shows you how to serve a Tensorflow 2 model on AWS Lambda. Or Joshua Jarvis’s Going Serverless for Your ML Backend with SAM CLI. For a more in depth discussion on what’s possible with ML and serverless, check out Datacast Episode 39: Serverless Machine Learning In Action with Carl Osipov.

What to do if PHP is still your jam… 🕺

Not to worry, the “Serverless LAMP stack” is definitely a thing. Ben Smith from AWS has another installment in his Serverless LAMP stack series, this time showing you how to build a serverless Laravel application and deploy it with AWS SAM.

And before you say, “hey, I bet Ben just made this whole thing up!”, Chandresh Singh also has a post that will show you how to setup a queue with Serverless Laravel using bref. If Laravel isn’t your thing, Smaine Milianni has a post that’ll show you how to deploy a Symfony application in AWS Lambda.

When you don’t want to repeat someone else’s mistakes… 🤦‍♂️

The Interwebs is filled with stories of success, but oftentimes learning what not to do can be even more instructive. Chris Plankey has a great post titled How I Failed at Generating Revenue with Alexa In-Skill Purchases that details his attempt to bring in some extra cash with a side hustle. We’re all prone to making bad assumptions, but maybe this will help you avoid a few.

Even if all your assumptions are correct, you’re still bound to hit some roadblocks when building out your serverless applications. Dimitri Saeys recounts how Sporza created a real-time sport data api (in tremendous detail). His team followed an interesting process, and there’s plenty to learn from their journey.

When you’re looking for a serverless solution to your problem… 🗺

If you still list DevOps on your LinkedIn profile, then perhaps using serverless for IAM user monitoring or sending bash commands to an EC2 cluster with AWS Lambda and SSM might be interesting to you.

For some simpler automations, Harish Aravindan can show you how to get notified on pull requests via Slack using AWS Lambda or you can see how Javaad Patel gets page views from Google Analytics using a Netlify Serverless function.

For the truly ambitious, Nghia Dang has an excellent post that shows you how to implement a highly available, scalable and cost-efficient video processing service using AWS Lambda, SNS and SQS. And if that’s not big enough for you, take a look at how AWS serverless architecture drives SBA’s Lender Gateway for PPP loans.

Where to go to level up your serverless knowledge… 🏗

Yan Cui compares choreography vs orchestration when dealing with serverless function composition. As he points out, both have their pros and cons, with Step Functions being the clear winner for mission critical workflows. Lots of useful information in here, but I still think there are cross-service use cases for Step Functions. Perhaps a discussion for another day.

Of course, Step Functions can get expensive, which is why Renato Byrro offers some suggestions on cutting Step Functions costs on enterprise-scale workflows. He mentions “orchestration” with EventBridge, but even though there are strong guarantees, this still falls into the “choreography” bucket for me.

If you’re still not fully up to speed on the magical service that is EventBridge, then perhaps this post on migrating applications to cloud with Amazon EventBridge by Emrah Samdan will fill in some gaps.

And speaking of magic, the new Direct Lambda Resolvers for AppSync are pretty darn cool as well. John Connerton not only helped build this new feature, but also explains why they are really effective.

Still thirsty for some serverless know-how? You can learn about Netlify Functions in 2-ish minutes, let Michael Bahr show you how to archive your AWS data to reduce storage costs, or get help from Ran Ribenzaft on how distributed tracing differs from logging. Plus, Lou Bichard can tell you why you’re alerting wrong with CloudWatch and Yossi Ittach will give you a rundown of your options for pub-sub services on AWS.

When you want to get hands-on with serverless… 👷‍♀️

Even though your code coverage is probably zero (don’t worry, I know you’ll eventually get to it), Mohammed Izzy shows you how to easily perform tests on your IaC code with Pulumi, so one less excuse. 😉

For those of you looking for a full-stack experience, Fidel Vazquez has a tutorial on designing and deploying a full-stack web application using AWS Amplify. Ashan Fernando shows you the simplest way to host a Gatsby website in AWS without servers, and Atila Fassina gives you the deets on deploying Netlify Functions with TypeScript.

Yi Ai has another excellent tutorial that shows you how to create an instance scheduler using AWS CDK, a common use case that I’m sure you’ll need to address at some point. You’re also likely going to need to process large S3 files with AWS Lambda, so give that one a look as well.

Simran Kaur Kahlon shows you how easy it is to setup an AWS Private API using Serverless Framework, and if you need multiple API versions in serverless microservices, Venkatachalam Dekshinamurthy will tell you how he does it (without using Route53).

If you’re ready to go with Go in Lambda, you might find this Ultimate Guide by Sebastian Karasiewicz handy. For something a little less involved, take a look at Adis Kovacevic’s post on how to add Algolia Search to Firestore using a cloud function.

When you need some serverless security best practices… 🔒

ICYMI: Serverless Security Strategies – A Recorded Session with AWS Principal Engineers
AWS Senior Principal Engineers Becky Weiss and Marc Brooker cover the most common areas of vulnerability including misapplied patches and updates, malicious code and runtime security, overly permissive access, and network segmentation, and share the ways that serverless technologies address these areas. This talk gives you a solid understanding of how a serverless security strategy functions technically and how it can be operationalized in your business. Sponsored

In addition to the excellent recommendations from Becky and Marc above, Anthony DiMarco offers up some best practices for serverless endpoints on AWS. For more insights into dealing with serverless security vulnerabilities, here’s how Cloudflare handles them.

Serverless certainly shifts more responsibility onto the developers, so it’s no surprise that security analysts want more help from developers to improve DevSecOps. After all, “only 15% of respondents said that a majority of developers participate in formal security training.” Couple that with the fact that a recent report showed misconfigured cloud storage services were prevalent in 93% of analyzed cloud deployments, it’s no wonder that the research suggests that cloud breaches will become faster and bigger. If you’re using serverless, you’re already in a much better position.

When you’re looking for some good serverless reads… 🤓

Corey Quinn brilliantly explains why multi-cloud is the worst practice. Not only does it force you to choose the least common denominator, but the likelihood of cloud agnostic workloads actually existing, is probably quite slim.

Sheen Brisals extends his theory of thinking and developing serverless applications as “Set-Pieces” in his most recent piece. This ties in nicely with Haim Raitsev’s Monolithic to Microservices post.

David Anderson explains how serverless helps enterprises scale DevOps, and how they did it at Liberty Mutual, while Brian Foody suggests that startups should be “Day One” Cloud Native Organizations.

I’m not sure who gave Forrest Brazeal the title of “Cloud bard”, but it’s spot on! He was interviewed on theCube and outlines common paths to failures (and successes) in enterprise cloud native evolutions. Unfortunately, there are no rap battles or cloud ballads performed during the interview. 🎹

Ben Ellerby has a great piece on Serverless BI and how serverless helps companies on their path towards data-driven Business Intelligence. And speaking of data, this early Twitter engineer has a suggestion for your next database.

When you’re looking for something serverless to listen to… 🎧

I had a great chat with Heitor Lessa on Episode #61 of the Serverless Chats Podcast. We discussed the the Well-Architected Serverless Lens and how best practices are defined, how services are chosen for the serverless lens, and what new services will be added to the Lens this year. You can also watch it on YouTube.

On Episode #23 of the Real World Serverless Podcast, Yan Cui talks with Ari Palo about how they do serverless at Alma Media and the third-party development tools they use to optimize their workflow.

When you’re curious what’s new with AWS… 🆕

AWS AppSync releases Direct Lambda Resolvers for GraphQL APIs, which we already mentioned, but it’s so cool that it deserves to be mentioned again. I’ve got nothing against VTL, but if you are rapidly prototyping something, this just feels like an easier way to get started. Ed Lima does a better job explaining it than I can.

AWS Lambda now provides IAM condition keys for VPC settings so you can ensure that users can only deploy functions connected to one or more allowed VPCs. Julian Wood gives some good use cases for it and why it might be right for you.

I just found out that Amazon API Gateway HTTP APIs now support wildcard custom domain names, which I didn’t realize wasn’t possible before they announced this. I’ve still yet to make HTTP APIs my go-to flavor of API Gateway. 🍦

In AWS ML news, Amazon Transcribe launches custom language models to let you add “out-of-lexicon terms.” In my experience, that includes most words in the English language 😬, but I’m sure it’s getting better all the time. Plus, Amazon Lex launches accuracy improvements and confidence scores, which will allow you to use business logic to help clarify intents. And AWS Step Functions adds support for Amazon SageMaker Processing with help from the Step Functions Data Science SDK. So that’s another thing I’ll add to my “probably need to learn this someday” list.

When you need some helpful serverless tools… 🛠

Neiman Marcus open sourced a Serverless Framework Plugin that gives you better control over Provisioned Concurrency Autoscaling.

Dynatron is a new NPM package that can “bridge between AWS DynamoDB Document Client and real world usage.” Gevorg Galstyan explains that this can find missing optimizations and hidden issues that are very hard to catch. Sounds interesting to me.

Midway Serverless is a “serverless framework used to build Node.js cloud functions and it helps you significantly reduce maintenance costs and focus more on product development in the cloud-native era.” Who doesn’t need another serverless framework? 😀

Final Thoughts 🤔

So, for those of you that have been around for a while, you may have noticed that I changed the format of the newsletter a bit. I’ve received a tremendous amount of feedback from a lot of you (which I greatly appreciate), and I’ve tried to start incorporating some of your suggestions. The biggest issue for me with the old format was that it had become terribly limiting, and in many cases, didn’t give me an opportunity to add the right amount of context. I have many more thoughts and ideas on additional changes that I plan on making (which I’ll share in a blog post soon), but I’m a sucker for feedback, so I’d love to know your thoughts.

I hope you enjoyed this newsletter. We’re always looking for ideas and feedback to make it better and more inclusive, so please feel free to reach out to me via Twitter, LinkedIn, Facebook, or email.

Take care,

Off-by-none: Issue #101

Tell us what you really think of serverless… 🤭

Welcome to Issue #101 of Off-by-none. Thanks for joining us!

Last week, we celebrated our 100th issue, and at the same time, realized we have a lot more to share about serverless! This week, we get some dissenting opinions on serverless while at the same time getting a bunch of awesome new tools to make it even better. Plus, we’ve got plenty of great posts from the serverless community.

Serverless News & Announcements 📣

New Relic pricing plummets with product overhaul
New Relic just released their New Relic One platform, which is a complete overhaul of their existing system. This is a great article that sums up the need to reposition in an increasingly saturated cloud observability market.

YC alum Paragon snags $2.5M seed for low-code app integration platform
This is an interesting new tool that is built on a AWS serverless backend. You still need quite a bit of technical knowledge, but most of the infrastructure is abstracted away for you. Give me a way to do IaC with this, and I might be very interested.

Announcing the New AWS Community Builders Program!
Looking to get access to AWS product teams, information about new services and features, mentorship from AWS experts, Promotional Credits, and other helpful resources to support content creation and community-based work? Check out this new program from AWS.

Rockset Shatters Operational Barriers for Real-Time Analytics
Maybe this is just an overhyped press release, but the idea of “Converged Indexes” that support real-time SQL queries on semi-structured data at massive scale is pretty exciting. I was just chatting with someone about RocksDB the other day, and they have been very happy with it.

Serverless Stories 📖

How I scaled an AppSync project to 200+ resolvers
If you’re working on a massive AppSync project, you definitely want to read how Yan Cui built one with over 200 AppSync resolvers and 600 CloudFormation resources.

How I Built a Serverless Search for My Blog
This is amazing. Probably total overkill, but amazing nonetheless. Gunnar Morling used Java and the Apache Lucene full-text search library, compiled into a native binary using the Quarkus framework and GraalVM, to deploy a serverless search engine on Lambda.

AWS DynamoDB: Writing millions of records: Not consuming provisioned throughput: Global Secondary Index and Sharding
This article does a great job explaining why write sharding might be necessary when using low-cardinality partition keys in secondary indexes. If you’re writing lots of data to DynamoDB, definitely give this a look.

Serverless Concepts 🏗

Understanding database options for your serverless web applications
Helpful post by James Beswick that outlines a few patterns that can be used to handle database interactions from your serverless applications. The relational database story for AWS and serverless is getting much better (thanks RDS Proxy), but it’s still not quite there yet.

The Pains of Testing Serverless Applications
Having difficulty testing your serverless applications? You’re not the only one. Paul Swail reveals some of the problems and complaints from developers collected through his recent serverless survey.

AWS Compiled 001
Alejandra Quetzalli has put together (what I think) is the first issue of an AWS newsletter. This one focuses on Java and Serverless. I hope there are more of these.

Best Practices for an Improved Serverless Developer Experience
I think Harsh Chaudhary has a lot of really good recommendations in here, but I’m personally not a huge fan of mocking cloud services locally. But, hey, whatever works for you. That’s what’s important.

Serverless Tutorials 👷‍♀️

Auto-instrumented, trace-centric observability for serverless & k8s
If you’re running distributed serverless, Kubernetes, or containerized environments, you need a specialized tool that’s built to monitor them. Epsagon enables teams to automatically detect, troubleshoot, and resolve issues within complex microservices with no training, manual coding, tagging or maintenance required. Try free today, connect your first trace instantly, and grab one of our “cloud observability” drones! Sponsored

Serverless Framework & Immutable Packaging: How to
Samuel Cozannet outlines a strategy for creating immutable deployment packages with the Serverless Framework. It’s an interesting approach, though it still requires the framework to rebuild the CloudFormation templates on every deploy. As soon as you throw certain plugins into the mix, everything goes out the window.

Why You Should Never, Ever print() in a Lambda Function
Paul Singman offers some advice for you to “upgrade your dance” when it comes to logging in your Lambda functions. Also, take a look at the structured logging format provided by AWS if you really want to take it to the next level.

Building well-architected serverless applications: Controlling serverless API access – Part 1Part 2, and Part 3
I love this series by Julian Wood. It takes you through all the steps and questions you need to be asking to make sure your serverless app’s API access is secure and well-architected.

Serverless Security 🔒

Study finds misconfigured cloud storage services in 93% of cloud deployments analyzed
I wish this came as a surprise. This has “led to nearly 200 breaches that have given attackers access to 30 billion records over the past two years.” 😳

Serverless Reads 🤓

The AWS Serverless LAMP Stack: The Future of PHP or Vendor Lock-in?
The good news about this article is that they don’t criticize serverless, just the proprietary nature of building a LAMP stack on top of Lambda and the AWS ecosystem. I’ll say one thing about vendor lock-in. If I had a nickel for every time I had to move my production application to another provider… I’d be broke.

My monolith doesn’t fit in your serverless
Gabriel Chertok gives some reasons why he thinks serverless isn’t right for apps that live somewhere between really simple and infinitely scalable. He makes some good points, and I’ve been arguing for awhile that I think we’ve added too much complexity to the serverless paradigm. What are your thoughts?

Why the Benefits of Serverless May Never Be Realized
“I think serverless as a whole has been over-hyped. It may be part of a broader cloud-native computing revolution, but serverless on its own falls short of being revolutionary. It’s a handy technology, but it’s not exactly a pathbreaking or singularly disruptive one.” I strongly disagree. Yes it has constraints, but I’ve never worked with a technology that offered this much potential.

For the podcast listener… 🎧

Episode #60: Going Green with Serverless with Paul Johnston (Part 2)
In part 2 of this two-part episode, I finish my chat with Paul Johnston about how the big cloud providers are addressing climate change, what the tech industry can do as a whole, the effect this will have on globalized business, and how the positive downstream impact of choosing serverless can create a more sustainable business.

New from AWS 🆕

Amazon Kinesis Data Firehose now supports data delivery to HTTP endpoints
This feature enables you to use a fully managed service to stream data to an HTTP endpoint without building custom applications or worrying about operating and managing the data delivery infrastructure. I’m down for that! It also supports data delivery to DatadogNew Relic, and MongoDB Cloud.

AWS CodeBuild supports code coverage reporting
This is a nice new feature. Supports any test framework that outputs files for JaCoco XML, SimpleCov JSON, Clover XML, and Cobertura XML.

Amazon GuardDuty expands threat detection coverage to help you better protect your data stored in Amazon S3
Threat detection coverage has been broadened to monitor for highly-suspicious data access and anomaly detection to help you better protect your data residing in Amazon Simple Storage Service. We now know that 93% of their customers need it. Read more.

Serverless Tools 🛠

Is serverless cheaper for your use case? Find out with this calculator.
Xavier Lefèvre has put together a really helpful serverless calculator that has a ton of default values already configured. You’re free to use the official AWS cost calculator, but this one assumes things based on a “typical” serverless application.

5 Serverless Security Tools You Should Be Using
Miguel Calles put together a list of serverless security tools for you. There are lots of other monitoring/observability tools available, but it’s a handy reference.

CLI tool to Query the AWS Aurora Serverless Data API
Chris Bailey wrote a python script that lets you query your Aurora Serverless cluster right from your CLI. Great little tool for debugging and development.

Serverless Star of the Week ⭐️

There is a very long list of people that are doing #ServerlessGood and contributing to the Serverless community. These people deserve recognition for their efforts. So each week, I will mention someone whose recent contribution really stood out to me. I love meeting new people, so if you know someone who deserves recognition, please let me know.

This week’s star is Nicole Yip (@Pelicanpie88). Nicole is an Engineering Manager at the LEGO Group, where, prior to her recent promotion (congrats!) she has been involved with the platform team looking after the hosting infrastructure (AWS), CI/CD and dev experience, SRE, operations and security for both application and infrastructure. Her experience as an infrastructure and DevOps engineer has allowed her to help teams of all sizes get their services to AWS. Nicole has also spoken at the Serverless Architecture Conference and DevOps Con. Thank you, Nicole, for helping others make the jump to serverless! 🙌

Final Thoughts 🤔

There were several new tools released this week that help with building serverless applications. From New Relic’s new platform, to TriggerMesh’s EventBridge integration, to Xavier Lefèvre’s Serverless Cost Calculator, all of these investments are a continued testament to the growing power and popularity of serverless.

While there were several articles this week that criticize serverless, it seems to be the same old recycled arguments, many of which have been addressed by the cloud providers or the community. We just need to keep fighting the good fight and spreading the serverless word. Eventually the dissenters will find themselves left in the dust with a whole bunch of servers to manage.

I hope you enjoyed this newsletter. We’re always looking for ideas and feedback to make it better and more inclusive, so please feel free to reach out to me via Twitter, LinkedIn, Facebook, or email.

Off-by-none: Issue #100

Celebrating 100 Issues! 🥳🥂

Welcome to issue #100! Thanks for being here! 🎉

Last week, we got a Q2 serverless recap, someone realized that NAT Gateways were expensive, and we learned how to model our serverless apps in a way that allows us to evolve them more easily.

This week, we’re celebrating the 100th issue of Off-by-none with what you’ve come to know, expect, and hopefully love: the many, many great serverless articles, projects, and tools from our community. But what’s more: I’m taking the time to reflect on the wonderful community we’ve built here, in your inbox, and sharing some ways I hope to improve your newsletter experience.

I’ve always wanted this newsletter to recognize the community’s vast and great work, and be inclusive and representative of those who are in it. I want you to feel like you’re a part of this newsletter and that you can see yourself in this community. To better accomplish that, I’m in the final stages of launching the new Off-by-none website. Though I’ve still got some work to do on it, it’s the vision of the site I am most excited about. I hope that it will be a place where I can facilitate more engagement, invite more submissions, ideas, and stars, and better amplify the many voices that make this community so great. If you have any suggestions, as always, please feel free to let me know, as I want the Off-by-none site to truly be a place for all of us. 🙌

Cloudflare launches Workers Unbound, the next evolution of its serverless platform
Oh wow, this looks amazing. Workers Unbound is meant for more complex and longer-running processes and operates at a fraction of the cost of Lambda, Azure Functions, and Google Cloud Function.

The AWS Serverless Application Model CLI is now generally available
In case you don’t know, the AWS SAM CLI is the command line tool companion for AWS SAM templates. It provides developers local tooling to create, develop, debug, and deploy serverless applications, and now it’s finally GA.

The Node.js Runtime
FYI, Google Cloud Functions now support Node.js 12 (in beta). I’d love to see Google become more competitive with some of their serverless offerings. Node 12 was released over a year ago.

Epsagon Further Accelerates Growth with New Investment from DTCP
Congrats to the team over at Epsagon! This latest investment brings their total funding to $30M which will help them increase their team to service their growing customer base. Apparently observability in the cloud is getting very popular.

Serverless Stories 📖

We went serverless with our new startup. And you should (probably) too.
I totally agree. Ankit explains why he chose serverless and what some of the benefits are. He gives some reasons when not to go serverless, but I think we’ve addressed those objections many times over.

A Plumber’s Guide to Cloud
Great post by Daniel Singletary, who took his experience as a plumber and applied the same troubleshooting methodology to complete Forrest Brazeal’s “Cloud Resume Challenge”.

A micro API in Firebase and Cloudflare Workers
This was a fun little experiment by Braeden Smith that compared building a simple micro API for loading an image in both Firebase and Cloudflare Workers. Fun Fact: Cloudflare won.

Serverless Use Cases 🗺

Serverless magic links with AWS Cognito
Here’s a really interesting use case for serverless that takes advantage of Cognito’s multi-factor login support to allow for temporary “magic links”. Thomas Schoffelen explains how secure it is, how it scales, and provides some code for a proof of concept.

Functions as a Service — A simple use case
Need to catch a webhook and publish a message to the Slack API? Pavel Pratyush explains why serverless is the perfect solution for this simple use case.

Processing PGP Encrypted Data in AWS Lambda using Python.
Here’s an interesting serverless use case. Mayank Madhukar shows you how to use python-gnupg to decrypt emails from an S3 bucket using Lambda.

Serverless Concepts 🏗

Real-time Data Processing With Kinesis Data Analytics
Nick Van Hoof and David Smits put together an excellent post that shows the serverless architecture they use to track, analyze and alert on traffic jams in Belgium using (near) real-time analytics processing. Very cool stuff.

Breaking Down Serverless Anti-Patterns
Parts of this post by Sarjeel Yusuf are a bit hard to follow, but the overall point should be well taken. We have to think and operate differently when building serverless applications, and in many circumstances, best practices are still a moving target.

Connecting Accounts with AWS Event Bridge
I like John Gilbert’s overall approach here, especially separating subsystems at the AWS account level to create bulkheads to contain the blast radius. I’m curious if there might be an alternative approach that doesn’t require upstream subsystems to know about other subsystems? Perhaps creating a common bus in a separate account that all subsystems can push to and read from?

Five Reasons You Should Consider AppSync Over API Gateway
Excellent breakdown by Yan Cui that outlines and explains five really good reasons to give AppSync another look.

Replacing web server functionality with serverless services
Another great post by James Beswick that explains how to significantly reduce your infrastructure requirements, setup time, and maintenance needs by switching to a serverless approach. Getting all that scalability and multi-AZ redundancy right out of the box should make the choice simple.

Serverless Tutorials 👷‍♀️

Implementing a Serverless Speech-To-Speech Language Translation App
Andre Beck started a series of articles that aim to illustrate the implementation of simple cloud apps on serverless platforms. First up is a language translation app that uses Step Functions.

How to handle duplicate Lambda invocations
Important message from Murali Allada about idempotent operations when dealing with asynchronous Lambda invocations. He suggests using DynamoDB, which makes a lot of sense, but you should also determine whether mitigating the side effects is worth the extra effort.

AWS CI/CD Pipeline Tools: CodeBuild and CodePipeline
Ran Ribenzaft walks you through setting up a CI/CD pipeline for a serverless project using CodeBuild and CodePipeline.

Creating an AWS SAM CLI project with Typescript and Both Types of Layers (Dependencies and Function)
Thinking about building a serverless Typescript project using AWS SAM? Nick Bordeau has you covered, complete with his project boilerplate.

Serverless Security 🔒

Twilio: Someone broke into our unsecured AWS S3 silo, added ‘non-malicious’ code to our JavaScript SDK
Note to self: Don’t enable S3 access policies that leave SDKs readable and writable by anyone. Otherwise, automated cyber-crime campaigns that prey on JavaScript code might infect said SDKs and take you over 8 hours to realize it.

Liberty IT Adopts Serverless Best Practices Using AWS Cloud Development Kit
Andrew Robinson wrote up a great piece (with the help of Matthew Coulter) on how Liberty IT is using the AWS CDK along with a number of best practices to create secure, repeatable deployments for their services. Nice mention of the CDK Patterns site as well.

Serverless for Enterprise: Scale big or go home
Using serverless for greenfield applications should be a no brainer at this point, but for enterprises with existing workloads, the choice isn’t always as clear. Mariliis Retter offers a few things enterprises should be keeping in mind as they start to make the transition.

What comes after Kubernetes?
I once knew an Ops person who said his primary role was to automate himself out of a job. And that’s what cloud providers are doing with K8s IMO. There are a lot more interesting things to be built on the infrastructure than there is to be done to the infrastructure. It’s just a matter of time until Kubernetes will be given as much thought as the hypervisor or Firecracker.

The Edge Computing Opportunity: It’s Not What You Think
Matthew Prince goes into detail about the future of Edge Computing and how Cloudflare Workers are addressing things like speed, cost, and most importantly, compliance.

Serverless or Kubernetes: When do you use which?
Pradeep Kumar lays out a number of rational arguments as to why you’d choose one over the other. I still think the choice isn’t just between FaaS and containers, though. There are so many other serverless “services” available, that trying to implement any of these on K8s would seem like a colossal waste of time and resources.

New from AWS 🆕

Amazon CloudFront adds additional geolocation headers for more granular geotargeting
This is an awesome update. You can now access a visitor’s city, state, and zip code, plus their timezone and approximate latitude and longitude. Lots of cool personalization that can be done with this

Amazon Elastic File System increases per-client throughput by 100%
Starting to play around with EFS and Lambda? Well, Amazon EFS now supports up to 500 MB/s of per-client throughput, a 100% increase from the previous limit of 250 MB/s.

AWS CodeBuild now supports accessing Build Environments with AWS Session Manager
Great feature if you need to dig in to diagnose complex build problems. Since you should be using CI/CD for all your production workloads anyway, this could become a handy tool.

Amazon Elasticsearch Services announces support for Elasticsearch versions 7.7
Nope, still not serverless, but new features are always welcome.

Amazon CloudFront announces Cache Key and Origin Request Policies
Another very cool update to CloudFront. You now have more control over your cache keys, and can even forward varying information to your origin, but still used the same cached content if necessary. Very cool.

Announcing AWS Serverless Application Model (SAM) CLI now generally available for production use
We already mentioned this at the beginning, but here is the official “what’s new” announcement. Good stuff from the SAM team.

Amazon Lightsail now offers CDN distributions to accelerate content delivery
This is an interesting way to take your “not-so-serverless” application and add a bit of serverless to it. Adding a CDN to cache assets and pages automatically is at least a good first step.
