Off-by-none: Issue #14

December 4, 2018

re:Capping re:Invent…

Welcome to Issue #14 of Off-by-none. I just spent a week in Vegas at AWS re:Invent and have I got a lot to share with you!

Last week we pondered if RDBMS were a good fit for serverless, overcame some common serverless objections and geeked out over serverless security. This week we’ll recap re:Invent, take a look at some of the amazing sessions and speakers, and review another 7,000 AWS product announcements (or something like that).

Buckle your seatbelt and let’s get started! 🏎

What to do if you’re suffering from re:FOMO… 😿

Unless you’ve been asleep for the last several months, you’re probably aware that AWS threw quite the shindig last week in Las Vegas. If you weren’t able to attend, don’t worry about it, we’ve got you covered. Because remember, what happens in Vegas, ends up on the Internet.

re:Capping re:Invent: AWS goes all-in on Serverless is my post that outlines some of the key announcements and what they all mean. I think I learned enough to write several books, so expect more posts to be coming.

What I learned from AWS re:Invent 2018 by James Beswick is also another great recap with a warning for cloud consultants and an important message about TCO. Paul Swail asks the question, What new use cases do the re:Invent 2018 serverless announcements open up? (answers included, of course). And if you want to read about all the Serverless announcements at re:Invent 2018, Alex DeBrie and Jared Short from Serverless, Inc. give you the full rundown.

When you’re looking for some really good conference talks… πŸ‘¨β€πŸ«πŸ‘©β€πŸ«

Advanced Design Patterns for DynamoDB (DAT401) 🀯
Rick Houlihan gave one of the most impressive talks of the entire conference. There were so many insights in this session that it was hard to keep track. He said, “We invented relational databases because storage was expensive” and “When people say NoSQL is missing JOINs, you say you’re missing the point.” He stressed that modeling NoSQL is difficult because you need to know and understand your access patterns upfront. But once you do, you can create a single table that can support 20 or more access patterns with just two or three Global Secondary Indexes (GSIs). Seriously mind-blowing stuff. Plus he stressed using serverless to validate your products. One of his best quotes was, “Don’t fail fast, fail cheap.” This could be the best 60 minutes you ever spend.

From Monolith to Modern Apps: Best Practices (SRV322) 🎸
Paras Bhuva and Tom Laszewski (with a little help from Fender’s VP of IT, Chris Ingraham) gave an excellent talk that outlined how enterprises are adopting serverless for a variety of use cases. Companies like Reuters and Hearst are using it for analytics, Finra is using it for fraud detection, and Expedia is using it for operations. Paras walks us through the design of a modern application and stresses that teams want/need to “reduce their undifferentiated heavy lifting.” It is a very interesting session that really highlights the power, speed, and diversity of serverless applications.

Serverless Architectural Patterns and Best Practices (ARC305) πŸ—Ί
Drew Dennis and Maitreya Raganath gave another really interesting talk that explored some architectural patterns and best practices. I see many people struggle with their serverless application designs because they aren’t quite sure how to stitch together all the managed services to create efficient pipelines. This talk looks at several common patterns including those for web applications, stream data processing, and data lakes.

Applying Principles of Chaos Engineering to Serverless (DVC305)
Yan Cui (aka @theburningmonk), gave an awesome talk on Chaos Engineering and how we can apply those principles to serverless. The topics in here are so good that I don’t think I can do it justice by trying to sum this session up. Just do yourself a favor and watch it.

A Serverless Journey: AWS Lambda Under the Hood (SRV409) πŸ‘©β€πŸ”§
Holly Mesrobian and Marc Booker took us on a deep dive into how Lambda actually works. Lots of really interesting information, but perhaps the best part of the talk was this…

Reducing the cold start VPC issue by using a secure tunnel with a remote NAT and no longer stealing hundreds of IPs from CIDR blocks in your VPC subnets? Yeah, that’s a pretty big deal.

Watch the talk

There were so many amazing talks that I can’t possibly list them all. Be sure to check out AWS’s playlist on YouTube for an extensive list of recorded sessions. You can also check out this post by Jennine Townsend that lists some of the more notable sessions.

Just when you think that AWS might be running out of ideas… πŸš€

Nope. Not only does AWS continue to make massive investments in its global infrastructure, hardware components and product offerings, but it also continues to break through the limits of serverless computing. Here are some of the important serverless announcements from last week.

When you’re still looking for some more serverless content… πŸ‘

Joe Emison wrote a really great article that discusses The Serverless Sea Change. The post goes deep into the impact that serverless can have on companies and outlines an example of the dramatic cost savings that can be achieved. He makes an astute point that “ten times more lines of code, is ten times more technical debt.” Spending more time researching and less time coding will make maintaining your serverless applications much easier and a heckuva lot cheaper. πŸ’°

Marcin Zasepa pointed out that Version 3 of the AWS SDK for JavaScript is written in TypeScript, so that’s pretty cool. πŸ€“

If you’re looking to jump in and start using some new AWS features, you can learn How to publish and use AWS Lambda Layers with the Serverless Framework.

You can also learn What’s New with Serverless at AWS during a webinar on December 11, 2018 @ 2pm ET. There are a lot of new things happening, so this might be a good opportunity to get a crash course.

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 Corey Quinn (@QuinnyPig). Corey is a cloud economist that helps companies save money on their AWS bills. But he’s also the brains behind the Last Week in AWS newsletter, host of Screaming in the Cloud, occasional blogger, regular conference speaker, and all around nice guy. Don’t let the snark fool you, he is a huge proponent (and user) of serverless technologies, but also a vocal critic of AWS when necessary (which keeps them honest and on their toes). Corey shared this newsletter last week with his audience and many of you are reading this because of him. So here’s a huge thank you to Corey for helping me spread the serverless word. πŸ™Œ

Final Thoughts πŸ€”

This was another long one, but last week was a whirlwind of information and announcements that have cemented serverless as the future of cloud computing. I want to thank AWS and all the support staff that helped put together and run this amazing conference. And I also want to thank AWS for continuing to support their customers and pushing serverless innovation. The next few years are going to be really exciting.

I hope you’ve enjoyed this issue of Off-by-none. Your feedback is always most welcome and much appreciated. Your suggestions help me make this newsletter better each week. Please feel free to contact me via Twitter, LinkedIn, Facebook, or email and let me know your thoughts, criticisms, and if you’d like to contribute to Off-by-none.

AWS just released enough products and features to keep us busy until next year’s re:Invent. So let’s go build some amazing serverless apps!

See you next week,
Jeremy
