 I... as Code (IaC)

• What is Infrastructure as Code? Infrastructure as Code (IaC) is a method of managing and provisioning computing infrastructure through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools.

• Why is IaC important? IaC brings a level of speed, consistency, and repeatability to infrastructure management that simply isn't possible with manual processes. It allows developers to automate the process of setting up and managing infrastructure, making it faster and more efficient to deploy and scale applications.

• Key Concepts in IaC: Some of the key concepts in IaC include idempotency (the ability to run the same code multiple times with the same result), immutability (once infrastructure is deployed, it is not modified, instead new infrastructure is built from code), and declarative vs imperative languages (declarative languages describe the desired state, while imperative languages describe how to achieve the desired state).

By understanding Infrastructure as Code, you're taking a significant step towards mastering modern Life Infrastructure management.
