Ansible was created by Michael DeHaan in 2012 and acquired by Red Hat in October 2015 for $150 million. It’s headquartered in Raleigh, North Carolina as part of Red Hat’s portfolio, which itself became part of IBM in 2019.
What makes Ansible stand out is its agentless architecture. Unlike tools such as Puppet or Chef, it doesn’t require any software installed on the machines it manages. It connects over SSH and pushes configurations directly. This makes it incredibly easy to get started — you can automate your first server in minutes.
Ansible uses YAML-based files called playbooks to describe automation tasks. The syntax is straightforward enough that even people who aren’t developers can read and write them. It’s got over 75,000 GitHub stars, making it one of the most popular DevOps tools ever created.
The ecosystem includes Ansible Galaxy, a community hub with thousands of pre-built roles and collections. Ansible Automation Platform (formerly Ansible Tower) adds a web UI, role-based access control, job scheduling, and audit trails for enterprise teams. Red Hat reports that thousands of organizations worldwide rely on Ansible for everything from cloud provisioning to network automation. The tool supports modules for virtually every major platform, including AWS, Azure, VMware, Cisco, and hundreds more.
