What is Infrastructure as Code (IaC) and what are its main benefits?

Infrastructure as Code means managing and provisioning infrastructure through machine-readable configuration files instead of manual processes.

Key benefits:

• Reproducibility: Spin up identical environments on demand.
• Version control: Track all infrastructure changes in Git. Know who changed what and when.
• Auditability: Compliance teams can review what infrastructure is being provisioned.
• Self-documentation: The code is the documentation.
• Disaster recovery: Re-create an entire environment from scratch in minutes.
