Discovering (or rediscovering) ssh tips and tricks we can use with (and without) Ansible
While a lot of people are using Ansible for easy ad-hoc tasks, using it in production to manage a fleet of servers spread all around the world can be challenging.
In this talk we'll cover how , for the CentOS.org infra, we tried to optimize the playbook execution and we'll mainly dive into ssh itself (so the presented options can also be used outside of Ansible).
We'll cover things like :
- SSH CA and certificates,
- how to use bastion/jump hosts , etc.
- Multi DC configurations

He then found the CentOS Project and quickly tried to be part of that community. Actually sysadmin for the CentOS.org infra
