Ansible is an open-source automation platform that simplifies IT infrastructure configuration, application deployment, and orchestration through human-readable YAML playbooks. Unlike other configuration management tools, Ansible is agentless and communicates with managed nodes over SSH, requiring no software installation on target systems. Developed by Red Hat, it enables teams to automate repetitive tasks across servers, networking equipment, cloud services, and containers from a single control point.
The platform uses a declarative approach where desired system state is described in playbooks, and Ansible ensures idempotent execution that safely converges systems to the defined state. Red Hat Ansible Automation Platform extends the open-source project with enterprise features including Automation Controller for centralized job scheduling, Event-Driven Ansible for reactive automation, and Ansible Lightspeed with generative AI assistance for writing playbooks. Over 140 Certified Content Collections provide pre-built automation modules across 60 or more technology partners.
Ansible targets system administrators, DevOps engineers, and platform teams who need to automate infrastructure provisioning, configuration management, and application deployment at scale. It excels in managing hybrid environments spanning on-premises data centers, public clouds, and edge locations. Ansible integrates with Terraform for infrastructure provisioning, Docker and Kubernetes for container orchestration, and CI/CD platforms for deployment automation, serving as a versatile glue layer across the entire operations toolchain.
