Abstract	With the cloud-native applications era, microservices architecture is now the de facto standard because it is scalable, flexible, and modular. However, it's extremely challenging to orchestrate the underlying infrastructure for such a distributed system, such as complexity, consistency, and governance at scale. To address these, automation through Infrastructure as Code (IaC) has emerged as a front-runner, allowing for declarative provisioning of infrastructure, while Policy as Code (PaC) enforces security, compliance, and operational policy governance through codified policies. This study tries to provide a holistic model that combines IaC and PaC to automate infrastructure provisioning and policy enforcement in a consistent way throughout the deployment pipeline. Through the use of solutions like Terraform for infrastructure and Open Policy Agent (OPA) to enforce policy, the model is proposed to enhance the speed of deployment, reduce human error, and achieve policy compliance.
Keywords	Infrastructure as Code, Policy as Code, Terraform, Open Policy Agent and Cloud-native Applications.
