Infrastructure as Code (IaC) enables engineers to specify infrastructure using code rather than manual configuration or actual hardware installations.
IaC is transforming DevOps by providing speed, scalability, consistency across environments, version control, and enabling collaboration between development and operations teams.
The IaC toolset includes Terraform, AWS CloudFormation, and Ansible, each with its benefits and ideal use cases.
While there is a learning curve and potential challenges in adopting IaC, its advantages in cloud computing and containerized systems make it a necessity for the future.
