The Mighty Lambda-lith 🗿

In our previous issue, I stood up for single table designs, AWS advanced zero-ETLs, and Lambda added support for .NET 8. This week, AWS makes some meaningful incremental improvements, Mistral goes GA on Bedrock, and Cloudflare announces a Firewall for AI. Plus, we have a ton of amazing content from the serverless community!

Serverless News & Announcements 📣

There weren't any major AWS serverless announcements this week, but I really appreciate the incremental improvements that make life easier for developers and solve some of those pesky edge cases. For example, this week Amazon EventBridge API destinations added support for content-type header customization. It may not seem like a big deal, but Nik Pinski does a great job explaining why it actually is.

Another example is AWS Lambda improving responsiveness for configuring stream and queue-based event sources. It used to take up to 15 minutes to propagate configuration changes. Now it takes less than 90 seconds.

And, Amazon Kinesis Data Streams added the capability to easily query data in the AWS Management Console. I'm not a Flink user, but being able to quickly run the occasional ad-hoc query without setting up an environment to run them is very handy.

AWS also announced that Mistral AI foundation models are now generally available on Amazon Bedrock (more details here). Check out the prices on this! 👀

In other cloud news, Cloudflare announces Firewall for AI. This is partially in response to a recently discovered vulnerability in an AI collaboration platform that allows bad actors to hijack models and perform unauthorized actions. Super. 👍

In lighter news, Jimmy Dahlqvist recently published his serverless journey on AWS with an accompanying Serverless Handbook that contains a collection of his learnings and experiences working with serverless and event-driven workloads on AWS.

Finally, a new site that collects ServerlessHorrors was recently released. So far these are focused mostly on users accidentally running up large bills on Vercel and Netlify. IMO, this is another misappropriation of the term Serverless. "PaaSHorrors" would have been more appropriate.
