Ansible is a simple IT automation system. It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. Ansible makes complex changes like zero-downtime rolling updates with load balancers easy.
I use ansible I various ways, like provisioning LXC or VM, installing apps and setuping environments in those, keeping my devices up to date etc..
