Terraform is an open-source Infrastructure as Code (IaC) tool developed by HashiCorp that allows you to define and provision infrastructure using declarative configuration files. Unlike imperative tools that require you to specify step-by-step instructions, Terraform uses a declarative approach where you describe the desired end state.
Key differences from other IaC tools:
Provider-agnostic: Works with multiple cloud providers (AWS, Azure, GCP, etc.)
State management: Maintains a state file to track real-world resources
Plan and apply workflow: Shows changes before applying them
Immutable infrastructure: Replaces resources rather than modifying them in place
