Partner with AWS Fundamentals

Most people I know worry about their AWS accounts' security. With no spending cap, this is a valid concern. Today, with LLMs & MCP servers, security becomes even harder. I love using MCP servers for AWS tasks, especially with the large set of official ones provided by AWS. The problem: if you run them locally via your own assumed role, or even remotely in some instance or Lambda function, you always have the issue of sticky long-term credentials...

I was thinking about the last big incident I was involved in. It wasn't the technical fix that was hard. It was the coordination. Who knows what? Who's doing what right now? What did we already try? incident.io solves exactly that...

S3 is rather cheap (~$0.02/GB/m) but what if you need a file system? Yes, EFS works but costs 15x more (~$0.30/GB/m). 💸 AWS sums down to: S3: 🟢 Cheap and unlimited scale ❌ Object storage API only EFS: 🟢 Works with whatever needs a file system ❌ Expensive as hell So if you look at 50TB, it's $1,000 vs. $15,000 per month...

Your $400/month S3 bucket just became $100,000/month. Here's what happened: You store all your files in S3 You connect your application (i.e. video editing, HPC, etc.) to S3 and do lots of I/O ops Your bill explodes because of S3 API costs What was the mistake? You've used S3 as a typical file system instead of only storing files. This can get expensive 💸...

honeycomb.io published a blog post called "The End of Observability as We Know It." I've been using observability tools for years now. Heck, I wrote a book about CloudWatch. And honestly? I like the take of this post. Let's see a typical daily observability issue: - You have 5 AWS accounts. - Each account runs different services that interact with each other. To be able to find issues you use tools that observability providers have built for you like: 📕 Logs 📊 Dashboards 🔮 Traces...

S3 wasn't designed to be a file system. But we keep using it as one. Here's what happens: Your app needs to read a 100GB file 📁 It makes 50,000 LIST requests. 200,000 GET requests. 30,000 HEAD requests. S3 charges per API call. Your $400/month storage bill? It becomes $100,000/month in API costs 💸 The real problem: S3 is an object store, not a file system...

We're using MCP servers with Teleport for secure data access. This lets team members request sensitive data through an internal LLM without direct permissions. The benefits: - Simplified onboarding - Fine-grained permissions for everything the LLM can do - Audits for everything Setup takes minutes to connect Teleport to AWS...
