Powerful: Why Orchestration is the thing
“This is what Ansible was written to do: Manage complex multi-tier deployments.
We don’t just stop at configuration management or application deployment. To really do orchestration, you must do all of those well AND be an outstanding workflow engine. Real world app stacks involve lots of different classes of systems all working in concert.”
Michael DeHaan Ansible CTO and project founder

“I wrote Ansible because none of the existing tools fit my brain. I wanted a tool that I could not use for 6 months, come back later, and still remember how it worked.”
