Off-by-none: Issue #340

October 14, 2025

The Growing AWS Graveyard 🪦

In our previous issue, AWS launched its API MCP Server, Supabase raised $100M, and the Data API Client v2.0 launched to make Aurora Serverless v2 simpler. This week, AWS GA'd AgentCore, EastiCache got vector search, and the AWS Graveyard just got a whole lot bigger. Plus, we have some amazing serverless and cloud content from the community!

News & Announcements

pre:Invent is here! AWS had a big AI week, announcing that Amazon Bedrock AgentCore is now generally available. I've had a mixed experience so far, but this is definitely a major upgrade from Bedrock Agents, giving developers a solid foundation for building agentic apps on AWS. If you’ve been experimenting with tool-calling or multi-step orchestration, this might be the building block you’ve been waiting for.

And what's the point of having AI agents if you can't observe them? CloudWatch’s new Generative AI Observability feature is also now GA, giving you visibility into prompts, latency, and token usage across your AI workloads. And also new this week: vector search for ElastiCache, enabling embedding retrieval right where your low-latency apps already live.

AWS also announced Amazon Quick Suite, a new collection of “agentic teammates” built to answer questions and take action on your behalf. What could possibly go wrong? Meanwhile, automatic quota management for AWS Service Quotas is now GA as well, quietly removing one of the most annoying operational bottlenecks in cloud history.

For the serverless crowd, don’t miss the Q3 2025 Serverless ICYMI roundup. Lots of exciting serverless progress from AWS you might’ve missed while actually building stuff.

On a more somber note, the AWS Graveyard just added several more residents. In a low key AWS Service Availability Updates post, AWS snuffed out a number of services that never quite hit their stride. Notable obituaries include Amazon S3 Object Lambda, Amazon Glacier, and Amazon CodeCatalyst. 🪦

Outside of AWS, CoreWeave launched the first publicly available serverless reinforcement learning platform for AI agents, whatever that means.

And finally, I made some additional enhancements to the Data API Client v2! In addition to its complete TypeScript rewrite, there's now drop in support for popular ORMs, smarter parsing, and a full mysql2/pg compatibility layer, all designed to make Aurora Serverless v2 fade quietly into the background.

Final Thoughts 🤔

It's been another busy week. I'm having so much fun working on open source projects again! I appreciate all the feedback and am glad people are finding the new Data API Client v2 useful. There's so much more we can do, so please send me your ideas, use cases, and (most importantly) your Aurora Serverless v2 challenges.

I also got a little bit of time to gather my thoughts on something I've been thinking about for quite some time. My essay, Intentionally Human: Product Managers in the AI Era, isn't an attempt to predict the future, it's talking about the reality that already exists. As always, I'd love to hear your thoughts.

Until next week,
Jeremy
