What are the popular Devops tools used for configuration management?

There are several popular DevOps tools used for configuration management. Some of the widely used ones are:

1. Ansible: Ansible is an open-source automation tool that allows for easy configuration management, application deployment, and orchestration. It uses a simple YAML-based language to define configurations and can be used for both server and network automation.

2. Chef: Chef is a powerful configuration management tool that uses a declarative approach to define infrastructure as code. It allows for the automation of infrastructure provisioning, configuration, and application deployment across multiple platforms.

3. Puppet: Puppet is another widely used configuration management tool that provides a declarative language to define infrastructure configurations. It allows for the automation of infrastructure provisioning, configuration, and application deployment across various operating systems and cloud platforms.

4. SaltStack: SaltStack, also known as Salt, is an open-source configuration management and orchestration tool. It uses a master-minion architecture to manage and control infrastructure configurations and can be used for both server and network automation.

5. Terraform: While not strictly a configuration management tool, Terraform is widely used for infrastructure provisioning and management. It allows for the definition of infrastructure as code using a declarative language and supports multiple cloud providers.

These tools provide various features and capabilities for managing and automating configuration changes, ensuring consistency, scalability, and efficiency in DevOps practices. The choice of tool depends on specific requirements, preferences, and the existing technology stack of an organization.
