So I have been using this for the last week and I absolutely love it. This is the browser based Claude Code dev environment running on AWS Lambda MicroVMs with S3Files as persistence. There are two blogs and a repo. Start here, it link to the others. edjgeek.com/blog/claude-...

Lambda MicroVMs + S3 Files: My Claude Code Sandbox for iPad — edjgeek

A walkthrough of building a browser-based Claude Code shell that runs in an AWS Lambda MicroVM with a persistent S3 Files home. Signed in with Cognito, deployed with SAM.

Today is CVPR Denver with AWS/Amazon. And it's all about Computer Vision. Something I haven't spent a lot of time with but decided to see how I could apply #serverless. Here is what I came up with. Check it out & if you're at CVPR come see me at the Amazon booth after 2! edjgeek.com/blog/9-tiles...

From 9 Tiles to 900: Scaling Computer Vision Pipelines — edjgeek

Computer vision pipelines are scale problems disguised as orchestration problems. You can solve both with a single function.

I get the allure of local MCP servers. Simple, easy. But "reinstall for the latest updates"? That's a SaaS lesson we already learned. OX Security put numbers on it. 200K servers, no auth. Wrote up why serverless is a safer default. edjgeek.com/blog/mcp-ser...

200,000 MCP Servers Are Exposed. Here's Why Serverless Is Safer. — edjgeek

MCP's most popular transport has no authentication. AWS serverless removes the conditions that make that dangerous.

I often hear about Lambda functions that spend most of their time waiting on I/O. Built a demo on Lambda Managed Instances to test the cost math. Not as clear-cut as I expected. edjgeek.com/blog/lambda-managed-instances/

Lambda Managed Instances: A Working Demo and the Math Behind It — edjgeek

Lambda Managed Instances let multiple invocations share the same CPU while waiting on network calls. Here's a working demo, the cost math, and when LMI actually saves you money.

Fun weekend project. My brother runs a pipelaying crew. I built him a calculator app but every change went through me. So I built a Telegram bot that lets him describe what he wants in plain English. An AI agent handles the rest. edjgeek.com/blog/pipelayer-agent

My Brother Doesn't Code. Now He Ships Features. — edjgeek

How I built a Telegram bot with Amazon Bedrock AgentCore and Claude that lets a non-developer iterate on a production PWA using plain English.

S3 Files just launched. Lambda functions can mount S3 buckets as a file system now. I built AI code review agents on it with a full SAM template. Durable function orchestrator, two Strands agents, shared S3 Files workspace. Every IaC gotcha documented. edjgeek.com/blog/s3-file...

Lambda Just Got a File System. I Put AI Agents on It. — edjgeek

S3 Files mounts your S3 bucket as a local file system in Lambda. I built AI code review agents that share a workspace through it, orchestrated by a durable function.
