Infrastructure as code(IaC) is a way to use source code, or formatted scripts, to define and manage the process of deploying and managing computer networks. The two popular camps for realizing this vision are imperative and declarative camps.

IaC is often mentioned in the automation practices in the context of DevOps. It is also known as a CCA, which stands for Continuous configuration automation.

Notable CCA Implementations

The two camps have their popular implementations. For imperative IaC, many uses Ansible as an example. For declarative IaC,Terraform is often mentioned.

Notable CCA tools include:
