Infrastructure as code (IaC) is the ability to provision and support your computing infrastructure using code instead of manual processes and settings1. IaC can be used to achieve automation, environment consistency, and standardization of computer resources in a cloud environment, as it eliminates the need for developers to manually configure and manage servers, operating systems, database connections, storage, and other infrastructure elements every time they want to develop, test, or deploy a software application2. IaC also enables developers to easily duplicate, track, and version their infrastructure, and to avoid configuration errors and drifts that can cause deployment failures2. IaC is an essential DevOps practice, as it enables faster and more reliable software delivery lifecycles2. References: 1: AWS, What is Infrastructure as Code? - IaC Explained; 2: IBM, Infrastructure as Code | IBM
