Infrastructure as Code (IaC) is a modern approach to managing and provisioning computer infrastructure through code instead of manual processes. This method allows developers and system administrators to define and manage infrastructure using configuration files, which can be version-controlled and reused. By treating infrastructure like software, teams can automate the setup and maintenance of servers, networks, and other resources, leading to increased efficiency and reduced errors. With IaC, changes to infrastructure can be made quickly and consistently, enabling faster deployment of applications. Tools like Terraform and Ansible are commonly used to implement IaC, allowing teams to create, update, and manage infrastructure in a reliable and repeatable manner. This practice enhances collaboration and streamlines workflows in software development and operations.
