Why is it important to have an infrastructure description in the form of code?

Infrastructure as Code (IaC) is important for several reasons:

• Repeatability and consistency: you can create identical environments without errors related to manual configuration.
• Automation: simplifies deployment and updating of infrastructure.
• Versioning: changes to infrastructure can be tracked and rolled back if necessary.
• Documentation: code serves as living documentation for the infrastructure.
• Speed and scalability: quickly scale and modify infrastructure to meet project needs.

Example using Terraform:

resource "aws_instance" "example" {
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "t2.micro"
}

This code describes a virtual machine that can be created and modified programmatically.
