Implementing Infrastructure as Code (IaC) in a cloud environment involves leveraging prominent tools and frameworks like Terraform, AWS CloudFormation, Google Cloud Deployment Manager, and Azure Resource Manager. These platforms provide the means to define and manage infrastructure using code, enabling automated provisioning, scaling, and management of cloud resources. By employing IaC tools, organizations can achieve consistent infrastructure deployment, version control, and rapid, repeatable updates, enhancing operational efficiency and agility in the cloud.
