Infrastructure as Code (IaC) is a popular approach to handling developer operations in software development today. It involves managing and provisioning infrastructure using configuration written as code, allowing for faster deployments, improved productivity and accountability, consistent infrastructure configuration and setup, and reduced human error. Two common IaC tools are Terraform and AWS CDK, each with its own benefits and features. Terraform uses a declarative approach, where you specify the resources and properties of the infrastructure to be provisioned, while AWS CDK uses an imperative approach, requiring engineers to specify instructions to provision infrastructure resources using code. Adopting IaC practices can help organizations improve performance, easily provision and maintain infrastructure, and focus more time and resources on releasing high-quality applications.
