also when you watch this make sure you look at all the patches on my jacket - IMO the best one is either 'friend to rats' or 'crudite creation'

My favourite pre:Invent launch so far - AWS just launched an AWS emulator, and it's built & maintained by thousands of AI agents! Get started at: aws.amazon.com/products/deve…

New AWS Emulator: test AWS code locally

A free emulator that runs on your machine and answers AWS calls the way AWS would. You point your SDK or CLI at it instead of AWS, and the source code is public under CC0

Every pod on an EKS node shares 1 kernel, so an agent running code nobody read is sitting right next to your other workloads. Nitro Sandboxes for EKS put that pod in its own VM, on a regular EC2 instance! I will put the launch blog and docs in the replies 🧵

New AWS Nitro Sandboxes on Amazon EKS: Hardware isolated pods

Nitro sandboxes for EKS give one pod its own VM, on a regular EC2 instance. Running your own lightweight VMs on EC2 has usually meant bare metal, but on Auto Mode its 1 line in the pod spec!

hello @fatjoe did you know there is a programming language called Lean? If you want me to teach you so you can make some good 'Lean Back' jokes please have your people call my people 🤝 (this is all I could think about every time you were sitting opposite me at NY Liberty Games)
