The Infrastructure as Code (IaC) has become a necessity in the managing of cloud-native and hybrid environments. This paper compares the large-scale implementation with Terraform, AWS CloudFormation, Azure Resource Manager and VMware vRealize Automation. A decentralized automation system was unveiled, which focused on template reuse, policy-as-code, CI/CD, and environment drift. Quantitative performance in systems using multiple clouds assessed the provisioning time, configuration, and deployment errors, success, and overheads. Findings indicate that Terraform and CloudFormation are more efficient than the alternative, as they are faster to provision, have reduced error rates, are more mature in automation, and result in a high cut in costs. This study offers a viable roadmap that enterprises may use to expand IaC, without losing governance, compliance, and effectiveness of operations
