AWS Systems Manager

ELI5 — The Vibe Check

Systems Manager is AWS's Swiss Army knife for managing your infrastructure. Need to SSH into a server without opening port 22? Run a script on 500 instances at once? Patch all your servers? Systems Manager does it all. It's the ops team's best friend — like having a remote control for every server in your fleet.
