Infrastructure as Code (IaC) can be defined as the process of provisioning and managing resources through definition files that are machine-readable, instead of physical hardware configuration or interactive configuration tools. In simple words, IaC can be referred to as the process of automating manual tasks required for IT resource management and provisioning, just through simple lines of code.
The Infrastructure as Code process involves the following 3 steps:
Step 1: The developers define and write the infrastructure specifications in a language that is domain-specific.
Step 2: The files that are created are then sent either to a management API, master server, or a code repository.
Step 3: The platform then takes all the necessary actions to create and configure the computing resources.
