AWS Systems Manager
Central operational hub — Parameter Store, Patch Manager, Session Manager — for automating OS patching, config management, and SSH/RDP-less access. Most-used open-source equivalent is Ansible for patching/configuration automation, paired with Teleport (already in your vault) for the Session Manager-style credential-less, audited access piece — the two together cover most of Systems Manager's scope.
