AWS Systems Manager
#64 · Level 2 · Scaling and resilience · Monitoring and operationsConcept
Section titled “Concept”AWS Systems Manager is a center for managing many servers together. Both kinds of machines — EC2 and servers in your own data center — can be connected to it (managed nodes). A small program called SSM Agent runs on each machine, and Systems Manager works there through it. Inside it are parts such as Patch Manager (applying updates), Session Manager (getting in safely without SSH keys), Run Command and Parameter Store. So you don’t have to log in to each server separately.

Why it’s needed
