RIP Redis 🪦

In our previous issue, cold starts were top of mind, Timestream and InfluxDB got cozy, and Bedrock gave us cheap AI Haikus. This week, Redis' OSS license change gets blowback, AWS updates their Savings Plan return policy, and we learn 5 simple steps for serverless resiliency. Plus, we have lots of awesome content from the serverless community!

Serverless News & Announcements 📣

In AWS news, Amazon DynamoDB now supports resource-based policies, letting you simplify cross-account access control for sharing resources with IAM principals of different AWS accounts. Yan Cui asks, "Is that a good idea?"

Also, AWS CodeBuild now supports custom images for AWS Lambda compute. I really like using Lambdas to do my builds, and adding them to CodeBuild had already made it a much more attractive option. Now with custom container image support? 👀

Do you have buyer's remorse after you locked yourself in to a 3 year Savings Plan? Well, AWS announced a 7-day return window. 🙌

And then there was the Redis debacle. 😔

In case you didn't hear, Redis is switching to Dual Source-Available Licensing that effectively kills the open source version, or at least the future of it. For some extremely interesting background on all this, check out Khawaja Shams' post: RIP Redis: How Garantia Data pulled off the biggest heist in open source history.

But there might be hope! Madelyn Olson, a Principal Engineer at Amazon ElastiCache and former contributor to Redis, posted: "I've gotten together with various former Redis contributors and we've started working on a fork: We are all unhappy with the license change, and are looking to build a new truly open community to fill the void left by Redis. Come join us!"

Having an open source software strategy has always been tricky, and commercializing it makes for an interesting challenge. I really do like Redis (the software not the company), so let's hope this fork works out.

And finally, Redpanda is now offering a serverless streaming option.

Serverless Tutorials 👷‍♀️

There were so many amazing tutorials this week. I had a hard time narrowing them down. One that stood out was 100% Serverless RAG on AWS by Fynn Fluegge. Really, really cool solution here.

And here are several other tutorials you don't want to miss, including several by the AWS team:

Star of the Week ⭐️

This week's star is Taylor Jacobsen (@taylorjacobsen). Taylor is the AWS Heroes Program Manager at AWS, responsible for planning, coordinating, and executing all the details of this amazing program. And knowing how difficult us Heroes can be, it's basically herding cats! 😀 But seriously, Taylor and her team bring together dedicated, community-focused experts from around the world to collaborate and make AWS better. The work she does inspires, recognizes, encourages, and enables AWS Heroes to do their best work to help others. Thank you Taylor for your continued dedication (and patience).

Final Thoughts 🤔

I've been playing around with building a web app using a combination of HTMX and Alpine for interactivity, Hono for the backend, Tailwind for styles, Fraglates for templating, and Ampt to deploy to AWS. It is absolutely amazing how much functionality and interactivity you can easy add without ever touching React or Vue. 🤯 I'll share more soon.

Until next time,

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 X, LinkedIn, or email.
