Terraform vs. Ansible: Simple Comparison for Beginners
Choosing the right DevOps tool can be confusing. Terraform and Ansible are popular tools, but they do different jobs. Let's make it easy to understand!
🔎 What Are They Used For?
TERRAFOEM
ANSIBLE
✅ Helps you create and manage servers, networks, and storage in the cloud.
✅ Supports cloud platforms like AWS, Azure, and GCP.
✅ Best for setting up infrastructure from scratch or making large-scale changes.
✅ Helps you manage and configure servers.
✅ Installs software, applies updates, and handles tasks like restarting services.
✅ Best for automating day-to-day tasks and fixing problems.
➡️ Think of Terraform as a tool to build a house and Ansible as a tool to furnish and maintain it.
🧾 How They Keep Track of Changes
🟢 Keeps a record of all your infrastructure (called a state file).
🟢 Knows what has changed and what needs to be fixed.
🟢Doesn’t keep a record or maintain a state file. It just runs the tasks you tell it to
➡️ Use Terraform when you need to track and manage changes over time.
🛠 How They Work
⚙️Uses HCL (HashiCorp Configuration Language) to describe what your infrastructure should look like.
⚙️Declarative: You describe the result you want, and Terraform figures out how to make it happen.
⚙️Uses YAML for instructions, like a checklist of tasks.
⚙️Procedural: You give it step-by-step instructions on how to get things done.
🚀 What They’re Best At
🌟 Building and managing cloud infrastructure.
🌟 Handling large-scale environments.
🌟 Configuring servers and applications.
🌟 Automating tasks like updates and software installations.
➡️ Many companies use both tools together: Terraform to build, Ansible to manage.
