Off-by-none: Issue #29

March 19, 2019

You can “serverless” too…

Welcome to Issue #29 of Off-by-none. It’s an honor to have you join us! 😊

Last week we were live at ServerlessDays Boston! This week, we’ll recap some of my favorite things from the Boston event, we’ll address some more #NoOps nonsense, and, of course, we’ve got plenty of great content from the growing serverless community.

There is a ridiculous amount of stuff to get to today, so buckle your seatbelts, and let get going! 🏎

When you’re wondering how ServerlessDays Boston went… 💥

It was “wicked” awesome! Seriously, as one of the organizers, I couldn’t have hoped it had gone any better. We had over 200 people attend, and other than a small snafu with the coffee being a bit late in the morning, the day went really well. The speakers were amazing, and thanks to Ann Guilinger’s live tweets, many were able to follow along even if they weren’t at the event. Ashish Addepalli also wrote a great follow up entitled, Learnings after a day at Serverless Days Boston. It’s loaded with some great takeaways.

And while all of the speakers were amazing, there were two talks in particular that really stood out to me. The first was by Ben Kehoe of iRobot. His talk, Applying the Serverless Mindset to Any Tech Stack, further pushed the idea that serverless is not about the technology you use, but instead about the focus on business value it enables. He wrote a brilliant followup piece, Serverless is a State of Mind, which I suggest you all read. Ben says to adopt the serverless mindset, and continue to move your organization up “the serverless ladder.”

The second talk I really appreciated was James Beswick‘s, Scared Serverless – What we learned after quitting servers for a year. As James told the story of his consulting firm transitioning clients to serverless architectures, and all of the roadblocks, small wins, set backs, and ultimate successes they had, you could tell that it resonated with audience. Whether you were a hardcore serverless veteran, or someone simply looking to get started, his message was refreshing, because it showed how powerful serverless ultimately is, but also that it will take time (and effort) to get there. This is highly reflective of my journey to serverless, and more real world talks like this are what people making the leap need to hear.

The videos of all the talks will be posted soon!

When you keep seeing #NoOps… 🤦🏻‍♂️

I recently came across two articles that continue to push the idea of NoOps. A NoOps state of mind and Make your existing solution tastier with serverless salt: NoOps, are both examples, IMO, of over-hyping that is detrimental to the serverless movement. While I certainly agree that moving to serverless dramatically reduces your operational overhead, there is still a significant amount of work to configure, monitor, and understand your infrastructure. That takes expertise and experience.

Both of the above articles ultimately admit that serverless isn’t actually NoOps, but instead a step towards it. And as Jamie Andrews points out in his piece, Why Serverless needs Ops, operational problems don’t go away in serverless, they become a lot more specialized. As organizations start forming serverless teams, understanding the skills necessary to staff them, is ultimately what we need to be exploring. Setting the right expectations for organizations will go a long way to successfully adopting serverless.

When you hear that serverless websites are the next big thing… 📰

Static Site Revolution: Top Websites Built with Gatsby
Sorry WordPress, but it looks like your days might finally be numbered (well, not really). Static site generators that are hosted on CDNs are becoming extremely popular, and this article outlines a few big sites that are taking advantage of the benefits.

Quickstart: Serve static websites serverless
But static site generation isn’t the only way to create “serverless” sites. Jonas Neustock’s post shows you a very simple way to generate HTML with a Lambda function. Probably not the cleanest (or most efficient) approach, but others are using these combinations to create interesting projects.

Webiny – Serverless CMS
Speaking of interesting projects, Webiny, a new open source “serverless” CMS has been released. There is a lot to unpack with this and from what I’ve seen, it’s packed with features. It appears to be cloud agnostic, but the database is MongoDB, so I think there is more work to be done.

Serverless Product Announcements 📢

Iguazio’s Platform Scales NVIDIA GPU-Accelerated Deployments
If you’re a data scientist that wants to seamlessly convert your research into production-scale ML projects, Iguazio’s recent partnership with Samsung SDS could blow your mind. Yaron Haviv, Igauzio’s CTO, gave me a demo of their platform yesterday and everything from the architecture, to the speed, to the developer experience blew my mind. I’ll be very interested in keeping an eye on their product offerings.

Discovering Issues Visually in your Serverless Architecture with Thundra
Distributed tracing in your serverless applications can be very helpful tool when trying to track down and debug errors. Thundra has added “Architecture” views that lets you visualize all your components along with the connections between them. If you spot an error, you can easily dig deeper.

Serverless Use Cases

Bringing realtime to serverless web applications
Here’s a great use case that is very popular, especially with distributed applications that need to handle some significant backend processing. James Beswick shows us how to handle this with AWS IoT and MQTT. A similar solution with API Gateway WebSockets would also be possible.

Building an Object Detection API with AWS S3, Rekognition and Lambda
Branko Blagojevic gives us a detailed walkthrough for another interesting use case that could process quite a bit of information at scale.

Publish to RabbitMQ from AWS Lambda
Why would you want to publish to RabbitMQ from your serverless application? Unfortunately, I have a use case for this. ☹️ But the good news is that if you are tethered to a RabbitMQ implementation, and you’d like to start migrating parts of it to serverless, you’re in luck.

Route53 Latency Based Routing made easy with Serverless
Sometimes caching at the edge isn’t enough, and we actually need to do more intense compute closer to our users. Route53 has quite a few options to ensure that users are routed to the right region, and this post will show you how to leverage Lambda to build a robust, globally available application.

gRPC to AWS Lambda: Is it Possible?
No, but the team at Coinbase sure gave it one heck of a try. I do like articles like this that try to push the boundaries of serverless. You always learn something new.

If you’re new to Serverless…

“A comparison between client-server and serverless full-stack app architectures”

When you’re curious what AWS has been working on… 🛠

AWS recently released an Open Distro for Elasticsearch. There was a companion article, Keeping Open Source Open, that talks about Amazon’s motivations. Of course, open source and cloud providers have been the subject of some recent controversy, and this was no exception. In On “Open” Distros, Open Source, and Building a Company, Elasticsearch creator, Shay Banon, is less than enthusiastic about AWS’s announcement.
