The drastic trend of DevOps or cloud-native technologies has necessitated the implementation of Infrastructure as Code (IaC) to streamline the infrastructure provisioning and management of the firms. IaC provides repeatable and consistent environments, reduces errors that are introduced manually to configure systems, and increases the scale and maintainability of infrastructure. As the best practice, the incorporation of IaC in the pipeline of Continuous Integration and Continuous Deployment (CI/CD) has become a part of delivering highly agile and robust deployment systems. This paper presents a detailed discussion on the automation of infrastructure provisioning tools (using Terraform, Ansible, and AWS CloudFormation) within the CI/CD cycle of events. We present the layered architectural pattern, which incorporates IaC into various pipelines of CI/CD. We also examine the mathematical models on resource dependency management and workflow optimization. To make the approach valid, different case studies and benchmarking outcomes are shown. It is estimated that the use of IaC substantially decreases deployment duration by as much as 65 percent, lowers configuration drift and improves fault recovery duration by 80 percent. To summarize, IaC has become the epitome of current DevOps approaches, and it allows achieving dynamic, scalable, and even secure infrastructures
