> what is ansible* ?
“Ansible is a configuration management,
application deployment and
IT Orchestration tool ”
"infrastructure as code"
synthesis of;
- configuration management, automation tools (Puppet, Chef, cfengine)
- deployment tools (Capistrano, Fabric)
- ad-hoc task execution tools (Func, pssh, etc)

- packaging software product (software | software+system)
- remote command execution
- auto scalability (system base, auto)
- be able to create same systems in case of emergency
- create different environments (dev, stating, load test)
