Can you name systems designed for automating configuration management in infrastructure?

Configuration management automation systems help centrally manage server and infrastructure settings, ensuring repeatability and scalability. Popular tools:

• Ansible — agentless, uses SSH, easy to learn.
• Puppet — client-server architecture, declarative configuration language.
• Chef — uses Ruby DSL, focused on programmability.
• SaltStack — fast, scalable, supports both push and pull models.
• Terraform — more for infrastructure as code, but also manages configurations.

These tools enable automation of deployment, updates, and maintenance of infrastructure in the desired state.
