Integration: Ansible can easily integrate with other tools and platforms, such as Git, Jenkins, and Docker, allowing you to create a complete automation pipeline.

Security: Ansible uses SSH for communication, which is a secure protocol. It also supports encryption of sensitive data using Ansible Vault.

Cost-effective: Ansible is an open-source tool, which means that it can be used without any licensing costs. It also doesn't require any additional infrastructure, making it a cost-effective solution for automation.
