Infrastructure as Code (IaC)

Definition and Benefits

• Infrastructure as Code (IaC) is the practice of managing and provisioning computing infrastructure through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools.
• Benefits: IaC enables version control for infrastructure, ensures consistency across environments, and allows for automated, repeatable infrastructure setups.

Tools and Practices

• Popular Tools: Terraform, Ansible, Puppet, Chef, AWS CloudFormation.
• Best Practices: Modular and reusable code, version control for infrastructure code, automated testing of infrastructure configurations, and continuous integration for infrastructure changes.

How DevOps Accelerates Development
