Low Latency Serverless Runtime ๐Ÿš…

In our previous issue, AWS introduced ClickOps to IaC, Public IPv4 addresses got a free tier, and we explored the post-serverless era. This week, JavaScript gets another new runtime, CodePipeline finally supports branch-based development, and we learn what to expect from serverless. Plus, we have plenty of content from the amazing serverless community!

Serverless News & Announcements ๐Ÿ“ฃ

Probably the biggest bit of serverless news last week was the introduction of LLRT (Low Latency Runtime), an "experimental, lightweight JavaScript runtime designed to address the growing demand for fast and efficient Serverless applications." And yes, it is fast, like faster than Go fast. It's experimental, it's missing some Node.js compatibility features, and who knows if AWS will ever officially support this. But I've never been one to bet against JavaScript. ๐Ÿ˜‰

In other AWS news, Amazon Bedrock console gets a modern look-and-feel, but considering the whole thing is only about a year old, I'm really curious what they were thinking when they launched the first "unmodern" version.

AWS AppSync is having a week. It now supports environment variables in GraphQL resolvers and functions, which is a big deal for some folks apparently, and it introduced 12 new Amazon CloudWatch metrics for enhanced monitoring.

Amazon SQS launches the Extended Client Library for Python to support payloads up to 2GB. This is another one of those productized patterns I've been talking so much about. I like these.

I saw that Amazon DocumentDB (with MongoDB compatibility) now supports text search. I don't use it, so I'm not sure how it compares to the capabilities of OpenSearch, but full-text search is a nice option to have.

AWS introduced Amazon Data Firehose, formerly known as Amazon Kinesis Data Firehose. Don't get too excited, they just renamed it.

And finally, CodePipeline supports additional trigger filters and new execution modes. The big news here is that they finally support branch-based development and monorepos.

I emphatically agree with Lee Gilmore on this one. Lambda FURLs are incredibly powerful, plus putting a CloudFront distribution in front lets you add WAF.
