  • It is an automation and configuration management technology.
  • It is used to provision, deploy, and manage compute infrastructure across cloud, virtual, and physical environments.
  • Easy remote execution and low barrier to entry.
  • Suitable for environments designed to scale rapidly.
  • Shares facts between multiple servers, so they can query each other.
  • Powerful orchestration engine. Strong focus on areas where others lack, such as zero- downtime rolling updates to multi-tier applications across the cloud.
  • Easy installation and initial setup.
  • Syntax and workflow is fairly easy to learn for new users.
  • Sequential execution order.
  • Supports both push and pull models.
  • Lack of master eliminates failure points and performance issues. 
  • Agent-less deployment and communication is faster than the master-agent model.
  • High security with SSH.

@Features:

  • Configuration Management
  • Security and Compliance
  • Application Deployment
  • Orchestration
  • Continuous Delivery
  • Provisioning
