I'm thrilled to welcome Retool as a Gold sponsor on the AWS News Feed! Go check out their AI Governance report, which found 93% of security leaders worry about vibe-coded tools in production, and only 8% call their governance strong. Link: buff.ly/IySnqYt

I replaced my GitHub runners with Lambda MicroVMs, and maybe you should too - new blog post on the Lambda MicroVMs released last week. They're really great! In the article and corresponding GitHub repo I outline the good, the bad, and the how-to use of MicroVMs as GitHub runners. Links below 👇

Damn, a ton of releases today! 1️⃣ CloudFormation Express mode - buff.ly/0oW6iGv 2️⃣ ACME support in AWS Certificate Manager - buff.ly/eAQCcOJ 3️⃣ Claude Sonnet 5 - buff.ly/7Ite0ot 4️⃣ AWS WAF support AgentCore Gateway - buff.ly/YxF9htr Find all of this and much more on the AWS news feed.

New AWS service deprecations, including Bedrock Agents Classic, Cognito Sync, Kendra, Q Business, and Simple AD 👇 aws-news.com/article/2026...

Last week I hosted a workshop session "build your first AI agent" at PostNL Engineering Day 2026. The workshop materials are now freely available on GitHub 👇 buff.ly/0kW7uX0 🐙 In a few steps you will learn how to add memory, tools, and an agentic loop. Feedback is welcome!

HUGE launch! AWS Lambda MicroVMs - Isolated virtual machines which can run tasks or sessions up to 8 hours. It’s like Lambda and Fargate had a baby, and it inherited the best genes of both. aws-news.com/article/2026...

"Grok 4.3 from xAI now available in Amazon Bedrock" aws-news.com/article/2026...

Claude's new model, Fable 5, is now on Amazon Bedrock. It is the same model as Mythos, but with additional safeguards in place. It's twice as expensive as Opus, at $10.00 per million input tokens and $50.00 per million output tokens 💸 aws-news.com/article/2026...

Have you seen the new popup to go ad-free on The AWS News Feed? Probably not, because I only show it once you've been active on the site for a while (2.2% of all cases). I haven't got many members yet, but 15% of people who saw the popup (17/109) clicked maybe later, which is a very good stat!

Did you see the new Ad-Free option in the AWS News Weekly Digest? It's a great way to support the feed and get a better experience in one go! Your membership keeps the feed alive and funds its development. Go check it out in the email or on the site!

Multi-Region Cognito User Pools! This has been a major request for the longest time. Also glad to see continued investment in Cognito - it’s a pretty cool service. aws-news.com/article/2026...

I was wrong. GPT-5.5 on Bedrock (left) is even more expensive than on Github (right).

They’re here! GPT-5.5 and GPT-5.4 are now available on Bedrock. Pricing isn’t live yet, but it will probably be cheaper than GitHub pricing 😬 aws-news.com/article/2026...

I had high hopes for Opus 4.8. It did not live up to them. (`echo hello world`, seriously?)

OpenSearch Serverless is finally truly Serverless, as opposed to its previous minimal commitment of $700/month! Very nice and long overdue improvement ❤️ aws-news.com/article/2026...

AWS now offers Claude Opus 4.8, Anthropic's most capable model, available through Amazon Bedrock and Claude Platform on AWS for advanced coding, autonomous tasks, and knowledge work applications.

Opus 4.8 has been released on AWS Bedrock, less than 6 weeks after the 4.7 release. Let’s hope this release is more willing to do work than the last one 😬 aws-news.com/article/2026...

I will give a PostNL-internal workshop "how to build your first AI agent" soon. The participants will learn about interacting with local data and external systems through tools and an agentic loop. To get them started quickly, I built a simple interface and display to interface with. Pretty nice!

Yesterday I released community voting on The AWS News Feed. But did you know your votes directly influence which articles make it to the daily digest email? So if you think everyone needs to know about a release, give it an upvote!

A long overdue update! AWS finally updates their SDKs retry policy from “insane” to “sensible”, including shorter retry delays for transient errors and limited retry attempts. aws-news.com/article/2026...

Did.. the AWS News Feed just get social? Yes it did! You can now vote articles up and down, Reddit-style. Let the world know what you think. And this is just the first step. I have many ideas to add more community insights to AWS News. Stay tuned!

Something's brewing at The AWS News Feed 👀

Anthropic has signed a deal to use "all of the compute capacity at [the SpaceX / xAI] Colossus 1 data center" which allows them to immediately raise session limits by 2x. Awesome news for Claude Code users, who have been in a serious compute crunch the past few weeks. buff.ly/86JDZSB

Woah some of the oldest AWS limits have been broken - IAM now supports 10k roles, 8k character trust policies, and 10k customer managed policies per account! aws-news.com/article/2026...

Dear diary, today I found my AWS News Frontend repo was missing push restrictions on the main branch. How did I found out? Because Claude Code committed straight to main, triggering an untested production deployment. In other news, The AWS News Feed now has infinite scroll. Oh well.

Pages might have a memory leak. Maybe.

Amazon is sunsetting their worst named service (impressive in itself) in favor of Kiro (one of their better products); Q Developer is now dead. aws-news.com/article/2026...

Ooooh this is a breakthrough: OpenAI GPT-5.5 and GPT-5.4 models are now on Bedrock! Limited preview for now, but I'm sure they will go GA soon. Perfect for review-by-different-model-family use cases! buff.ly/dEmsMh5

VPC Egress is a nice addition to Bedrock AgentCore Gateway. If every API is a tool, private APIs should definitely be in the mix! Amazon Bedrock AgentCore Gateway and Identity support VPC egress aws-news.com/article/2026...

There are times The AWS News Feed daily digest surprises me… and I built the darn thing! There are just so many releases, it’s too easy to miss some. But on AWS News the crowd determines the most popular articles, they end up in my inbox every day, and I never miss an important announcement ❤️

I've followed the hype and tried Caveman. After a few hours, I'm convinced it's a bad idea. By reducing everything to caveman talk, context, nuance and details are lost. LLMs match the output to the input style, so hooga-booga in is hooga-booga out. We all want to save tokens, but this ain't it.

This is how it starts - Claude Code now denies Opus 4.6 ever even existed. It was all just a fever dream 🤨

Opus 4.7 is now available in Amazon Bedrock! Let’s hope the Claude limits for Opus 4.6 and Sonnet go back to normal now 😅

Working on some diagrams for a doc on AI SDLC and I accidentally created this, which might turn out to be prescient..

I built a sponsor dashboard for The AWS News Feed. It's still insane to me how easy this has become for side projects. This was about an hour of work!

Do you think The AWS News Feed looks like crap? Personally, I do. And I don't have the skills to do better - so now I'm talking to a design agency to create a proper UI/UX design! But real quality costs real money, and the feed is (and will remain!) free to use. So I'm looking for sponsors! [cont]

More goodies from AWS: regional capabilities (services, APIs, CloudFormation support) are now programmatically accessible through S3, at no cost! aws-news.com/article/2026...

AWS now provides programmatic access to Regional availability data for services, APIs, and CloudFormation resources through Amazon S3, enabling organizations to automate deployment validation and multi-region planning workflows.

This is useful: AWS AgentCore Agent Registry to keep track of all agents (A2A and MCP) in your organization, promoting reuse and preventing duplication. aws-news.com/article/2026...

I guess it was inevitable - S3 is a filesystem now. It has full NFS compatibility, and uses an actual EFS storage layer for active files. Does this finally settle the question “is it a file or is it an object”? aws-news.com/article/2026...

Excuse me? Claude Ultraplan? Big Power Rangers vibes.

A few days ago I wrote a blog about semantic search, embeddings, and S3 vector buckets. Today I ran into this beautiful trace which captures the entire process. I just love a well-instrumented distributed system ❤️

Ooh native OTel ingestion support for CloudWatch Metrics 👀 This is both very cool and potentially very expensive for high-cardinality metrics 😬 aws-news.com/article/2026...

New blog post! Introducing semantic search to AWS News - a deep dive into embeddings, vector buckets, and more. lucvandonkersgoed.com/2026/03/31/i...

It's official now - App Runner is out. As is CloudTrail Lake 😢 Check out the full list of service deprecations below 👇 aws-news.com/article/2026...

Lol yeah no lie detected

MAJOR update 🚀 The AWS News Feed now supports Content Search! You can now search for any term and the AWS News Feed will find instantly find any article discussing it. And it's super fast - powered by S3 Vector buckets. Go try it out now! Link in the comments 👇️

Amazon S3 now supports account regional namespaces for general purpose buckets, allowing you to create uniquely named buckets within your account and region with automatic suffix protection and simplified management across multiple AWS Regions.

AWS finally found a way to allow "duplicate" S3 bucket names.. by adding an account / region suffix 😅 aws-news.com/article/2026...

I am immensely happy to welcome local hero Cloudar as a 5-month silver sponsor on The AWS News feed! Go check out their AWS consulting and MSP services. Thanks for your support, Cloudar!
