Infrastructure as Code (IaC) is a methodology that automates the provisioning and management of infrastructure resources, such as servers, networking components, and security settings, using machine-readable configuration files rather than manual processes. This approach allows for consistent, repeatable, and scalable deployments across various environments, reducing errors and accelerating delivery times. IaC practices are integral to software development operations (DevOps) as they facilitate collaboration between development and operations teams, ensure infrastructure consistency, and promote version control for infrastructure components similar to that of application code. By treating infrastructure as a part of the application stack managed through code, organizations can streamline their IT operations, improve security and compliance posture, and foster innovation by enabling rapid experimentation and deployment of new services. IaC tools, such as Terraform, Ansible, Chef, Puppet, and AWS CloudFormation, provide the necessary capabilities to declaratively define, version control, and manage infrastructure resources, bringing a higher level of automation, predictability, and efficiency to IT operations within the Software DevOps context.
