Q&A

What is the difference between Terraform and Ansible?

Terraform is mainly used for infrastructure provisioning, while Ansible is a configuration management and automation tool. Terraform focuses on creating and managing the infrastructure, while Ansible handles configuration and deployment.

Can Terraform be used with cloud providers other than AWS?

Yes, Terraform supports over a hundred providers, including other cloud providers like Azure and Google Cloud. You can use the same Terraform configuration files to provision infrastructure on different platforms.

How does Terraform ensure infrastructure changes are applied correctly?

Terraform uses a state file to keep track of the current infrastructure state. When you make changes to the configuration files, Terraform compares the desired state with the current state and executes the necessary actions to reach the desired state, ensuring changes are applied correctly.

Can Terraform be used for managing existing infrastructure?

Yes, Terraform can also be used to manage existing infrastructure. By importing the current infrastructure state into Terraform, you can make changes, update configurations, and track the state of your infrastructure in a consistent and automated manner.

Is Terraform suitable for large-scale deployments?

Yes, Terraform is designed to handle large-scale deployments. It provides scalability, reliability, and automation capabilities that make it suitable for managing infrastructure at any scale, from small projects to enterprise-level deployments.
