Stop asking: “Which EC2 instance should I use?” … and ask instead: “What does one unit of my work cost, at the latency my users need?”
That was the idea behind today’s EC2 performance workshop at SREcon EMEA ;-)

🧵 I rebuilt my Python AI tools in Rust and got 10x+ performance gains.
But the real revelation wasn't about speed—it was about safety in an era where AI writes code.
Here's why Rust might be the AI language of the future 🦀
