@Steve_Yegge Your next reply to Ernie should tell him to ignore any calendar conflicts and prioritize your meeting!

[Brooke Jamieson @brooke_jamieson]

Jeff is the whole reason I am a developer advocate!
I had no idea this was a job until I saw him speak in Melbourne, then I realised I was born to do this job and made it my mission to get hired by aws (which also meant moving to the other side of the planet)
Thank you @jeffbarr

[AWS Developers @awsdevelopers]

we just dropped an MCP server, have you set it up it yet?

→ full AWS API coverage
→ sandboxed script execution
→ real-time documentation access

[Claude @claudeai]

The Claude Platform on AWS is now generally available.

AWS customers get the full set of Claude API features, with AWS authentication, billing, and commitment retirement.

[AWS Open Source @AWSOpen]

Open source maintainers shouldn't have to absorb the cost of AI finding bugs at scale.

$12.5M from AWS, Anthropic, Google, Microsoft, and OpenAI → tools, automation, and resources through Alpha Omega to help projects validate, triage, and fix faster.

@brooke_jamieson Or they will make you take some train-ing.

[Tobias Schmidt @tpschmidt_]

Anthropic just launched an AWS Serverless plugin for Claude Code 👾
It knows serverless patterns!

• Lambda, API Gateway, EventBridge, Step Functions
• Scaffolds with SAM or CDK (defaults to TypeScript + CDK 💪)

Amazon Quick has Google Gemini beat!

HyperFRAME Research is homogeneous in our deployment of Google Workspace, we don't use Slack, Teams, or Zoom, we are 100% Google. You could say we are all-in on Google.

Stephanie Walter and I have been playing with Google Studio and the various Gemini features for weeks now, trying to do one simple thing:

"Go through all of my emails and find every email with the term "sow" or "statement of work" and then create a Google sheet with all of that info arranged into the following columns: name | email address | Company | short summary of the discussion | date of last interaction.

Google has spectacularly failed, after hours of trying, to perform what I think is a simple task. Especially since it has access to all of the data and has one of the best frontier models in Gemini. Epic fail, and even asking Gemini to help was an epic fail. Gave up...

Amazon Quick has gone from downloading, giving it permissions, to task completed in 25 minutes! And that is with me stumbling around with a new UI and not really knowing what I am doing.

The process was not one and done, and it took about 10 interactions to give permissions and review output, but 25 minutes later, the task was done.

Mind blown 🤯

@seeedstudio This looks cool but you don't have the right S3 permissions on the PDF and I cannot download it.

@seattlestorm @ClimateArena See you all tomorrow!

@PrintPerspec I have the same blower. Where can I find the STL?

[Jeff Barr ☁️ @jeffbarr]

@PrintPerspec That really sucks!

[Jeff Barr ☁️ @jeffbarr]

We had a lot of fun reviewing my old photos and creating some fresh content for this video that recaps my many visits to Japan on behalf of AWS.

[Amazon Web Services @awscloud]

In the 80s, @jeffbarr got lost in Japan.

He never really left.

He’s been back to JAWS-UG 10 times.

Amazon #S3Files went GA on April 7th, and while there are plenty of setup guides floating around, the article below takes a more architectural lens. It digs into what layers in your stack become unnecessary when S3 buckets can be mounted as NFS file systems from EC2, Lambda, EKS, and ECS.

There is a good discussion included on the tradeoffs involved. The ~60 second commit interval, rename costs, the 50 million object threshold, VPC requirements. It maps out where S3 Files genuinely removes friction and where you still need to design carefully around its constraints. Check out this really good article from Kento Ikeda! #s3 #aws
