Off-by-none: Issue #341

The Cloud That Broke The Internet 💣

In our previous issue, AWS GA'd AgentCore, EastiCache got vector search, and the AWS Graveyard got a whole lot bigger. This week, AWS gives everyone a snow day, Bedrock finally automates access to foundation models, and Caylent and Trek10 take their relationship to the next level. Plus, we have plenty of awesome content from the serverless and cloud communities!

News & Announcements

Let’s start with the elephant in the room: Amazon had a DNS outage that temporarily broke large chunks of the internet this week. The good news? It’s all back to normal. The bad news? People are losing their minds over this and thinking that a T1 line to their garage would be more resilient.

In it-is-about-damn-time AI news, Amazon Bedrock now automatically enables access to its serverless foundation models, eliminating the manual step in the console that made any form of automation impossible. Also, Claude 4.5 Haiku is now available in Bedrock. If you're looking for a smaller, faster/cheaper sibling of Sonnet 4.5 that’s perfect for lightweight, high-throughput agentic tasks, give this model a look.

On the serverless and dev-tools side, AWS SAM CLI added support for Finch, giving you another local option for testing Lambda functions. And Application Load Balancer got a nice quality-of-life update with URL and Host Header rewrites, finally eliminating the need for those messy routing workarounds we all hated.

If you've been wanting to try Kiro, AWS's new Cursor-like AI coding tool, the wait is over. It’s early, the reviews are mixed, but it’s now open to everyone and probably worth keeping tabs on.

Finally, Caylent acquired Trek10, creating what they’re calling the most comprehensive dedicated AWS services partner in the industry. I've been working with Caylent as a partner for over a year now, and I knew some amazing folks at Trek10. This is definitely a powerhouse.

The Serverless Monolith: Is It time to reconsider?
Khalid Bourhaba makes his argument for why monolithic serverless apps aren't the typical monolith of yesteryear. And I agree.

AWS Introduces ECS Managed Instances for Containerized Applications
Renato Losio pointed out that besides trouble managing DNS, AWS also may have flopped with their new ECS Managed Instances release.

LLMs are the End of Serverless
Anuj Tomar makes a valid point. Claude and OpenAI likely have a much better understanding of containers than they do serverless. Then again, anyone building anything serious on AWS shouldn't be one-shotting an app with a vibe-coding tool.

AWS just reminded everyone what a single point of failure looks like
Yes, the AWS outage took a lot of sites and services down, but I'm willing to trade a few hours of downtime every year or so to get all the other benefits. Also, I thought the blog image was quite clever. 🙂

Thoughts from Social

Earlier this year, a heart condition almost took everything from me. ❤️‍🩹

Years of stress and burnout had finally caught up, then life threw more at me.

It’s been the hardest year of my life. This is a deeply personal story of how I found my rhythm again.https://t.co/usgUeOj8Jk

Final Thoughts 🤔

My personal essay above says it all this week. I hope you are well and taking care of yourself physically and mentally. There is nothing more important.

Until next time,
