No matter what the complexity of the tasks, it all boils down to running an Ansible

module, which makes playbooks easy to write and easy to review later.


• All you need is Python + a playground server with SSHD • Ansible is agentless, so setup can be done in minutes • Playbooks are intuitive • Ansible is rich with built-in modules for trivial to complex tasks

Simplicity1

15


• Idempotence enables Ansible to be declarative & also reliable • We can run multiple times without changing the result beyond the

initial execution

IDEMPOTENCE2

16


• Every script we write is used two times • once, when deploying a new version • and again when provisioning a new server

• Using tags we run or skip tasks or plays as needed.

REUSABLE3

17

./playbook.yml -i hosts -- --tags infra


• Ansible can be easily extended with JSON • Correlating monitoring alerts with application deployments

significantly reduces MTTR

EXTENSIBLE4
