Infrastructure as Code (IaC): Terraform vs Ansible vs Pulumi

Infrastructure as Code (IaC) automates cloud environments using declarative or programmatic configuration. Terraform, Ansible, and Pulumi are the most widely used tools in modern DevOps workflows.

Tool Comparison

• Terraform: Declarative, cloud-agnostic, state-based provisioning
• Ansible: Agentless automation for configuration and orchestration
• Pulumi: IaC using real programming languages like TypeScript or Python

Which should you choose?

Terraform excels in multi-cloud provisioning, Ansible in configuration automation, and Pulumi in developer-centric workflows.
