What are configuration management tools like Ansible, Puppet, Chef, or Salt used for?

Configuration management tools such as Ansible, Puppet, Chef, or Salt are used for:

• Deployment and configuration automation: They enable automatic installation of software, configuration of operating systems, and management of files and services across a large number of servers.
• Ensuring consistency: They guarantee that all servers in the infrastructure are in the desired, standardized state, reducing the risk of configuration discrepancies.
• Change management: They simplify and control the process of making changes to server configurations, allowing rollback to previous versions if necessary.
• Increasing efficiency: They reduce the need for manual operations, freeing up time for system administrators and DevOps engineers.
• Improving fault tolerance: Rapid deployment and restoration of configurations help reduce downtime during failures.
• Ensuring security: They allow centralized application of security policies and updates, reducing the attack surface.
• Infrastructure documentation: Configuration code serves as living documentation of the current system state.
