Ansible vs Terraform

Terraform and Ansible are both infrastructure automation tools but they operate at different layers. Terraform provisions infrastructure — creating VMs, networks, databases, and cloud resources. Ansible configures what's already running — installing packages, managing files, deploying applications, and orchestrating multi-server operations.

Terraform is declarative and stateful. You describe the desired infrastructure state in HCL, and Terraform figures out what to create, modify, or destroy to reach that state. It tracks everything in a state file. This makes infrastructure reproducible and version-controlled.

Ansible is procedural and agentless. You write playbooks that describe steps to execute on servers via SSH. No agent installation needed — if you can SSH to a server, Ansible can manage it. This simplicity makes Ansible excellent for ad-hoc tasks, configuration management, and application deployment.

Product Overview

Ansible

Description: Ansible, an open-source automation tool for configuration management, application deployment, and task orchestration. Using a simple, human-readable language, Ansible enables efficient automation of IT infrastructure. It streamlines complex tasks, promotes consistency, and empowers teams to manage infrastructure as code.

Terraform

Description: Terraform, an Infrastructure as Code (IaC) tool by HashiCorp. Streamline and automate the provisioning of infrastructure across cloud providers. With a declarative configuration language, Terraform enables users to define, manage, and version infrastructure as code, promoting consistency and scalability.
