Off-by-none: Issue #65

November 26, 2019

Serverless is a journey, not an event destination… 🪐

Welcome to Issue #65 of Off-by-none. It’s great to have you here! 😎

Last week, we looked at the first major batch of announcements and feature launches leading up to re:Invent. This week, there were about a thousand more (give or take 😉)! We’ll try and cull that list down for you, plus we still have plenty of content from the serverless community.

Before we jump in, I just want to thank the sponsors of the #ServerlessForEveryone Community Party @ AWS re:Invent 2019. StackeryThundra, AWS, CloudZero, Lumigo, Protego, Serverless, Inc., Edrans, and New Relic Serverless have made this entire event possible.

Okay, now prepare for serverless announcement overload! 🤯

Guides to at Serverless re:Invent 🗺

re:Invent is going to be a nonstop onslaught of information, technical sessions, product announcements, parties and more. Here are some guides to help you plan your time. (BTW, if you’re not going to re:Invent, take note of some of these sessions and watch the videos once they’re posted.)

AWS re:Invent Serverless Survival Guide
Trisha Paine provides a list of can’t miss re:Invent sessions for developers, cloud architects, and security folks.

This is an interesting use case that merges audio files using Lambda@Edge to deliver audio responses to Alexa. Stephane Couzinier explains the whole process (including a CI/CD pipeline) and provides the finished code.

Serverless Security 🔒

How to build secure serverless applications for PCI-DSS compliance?
Thinking about storing data that requires PCI-DSS compliance? My advice: DON’T. But if you need to, this article from Ryan Jones will get you asking the right questions.

When the teams at AWS can’t even wait until re:Invent… 🤷‍♂️

Once again, AWS has flooded us with a plethora of announcements regarding new features and products. I haven’t had the time to read through all of these, let alone actually digest and process what they mean. I’ve included 54 links here to the announcements and related blog posts, and there are even more on the What’s New blog! I’m listing all of the ones that seemed interesting and relevant to serverless, and categorized them the best I could. It’s going to take us awhile to make sense of all these, so stay tuned for more in-depth analysis in the weeks to come.

Upcoming Serverless Events 🗓

There are a lot of upcoming serverless events, webinars, livestreams, and more. If you have an event you’d like me to mention, please email me.

December 2-6, 2019 – AWS re:Invent 2019

December 3, 2019 – Taco Tuesday with the AWS Heroes

December 4, 2019 – #ServerlessForEveryone Community Party @ AWS re:Invent 2019

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 Ryan Kroonenburg (@KroonenburgRyan). Ryan is the co-founder of A Cloud Guru and an AWS community hero (you might remember when I featured his brother Sam a few weeks ago). When Ryan was a solution architect five years ago, he taught himself AWS, and realized the community was underserved in AWS courses. Fast forward to today, and Ryan’s work with A Cloud Guru has reached over one million students and he continues to teach the community about AWS, serverless, and the cloud. Thank you for making serverless accessible to all who want to learn, Ryan! 🙌

Final Thoughts 🤔

I don’t know about you, but my brain is fried from trying to process all these new AWS serverless announcements, and we’re still over a week away from the big keynotes at re:Invent. I have so many things I want to write about and share, but with all this information to look at, there just isn’t enough time in the day. And if you’re feeling overwhelmed, don’t sweat it. I have a feeling that we’ll be seeing some excellent posts, videos, and tutorials from the serverless community over the next few months to help us make sense of it all.
