What tools for automating server and infrastructure configuration with code are you familiar with?

I am familiar with several tools for automating server and infrastructure configuration through code:

• Ansible — a simple SSH-based tool that allows describing configurations in YAML (playbooks). Suitable for configuration management and deployment.
• Terraform — a tool for declarative infrastructure description (Infrastructure as Code), supporting many providers (AWS, GCP, Azure, etc.). It enables creating, modifying, and versioning infrastructure.
• Puppet and Chef — more complex configuration management systems that use their own DSL or Ruby, well-suited for large infrastructures.

Mostly, I have used Ansible for server setup and Terraform for managing cloud infrastructure, which allows maintaining infrastructure as code, easily scaling, and reusing configurations.
