Terraform is an open-source Infrastructure as Code (IaC) tool used to create, manage, and update cloud infrastructure using code instead of manual steps.
With Terraform, you write configuration files to automatically create resources like virtual machines, networks, storage, databases, and load balancers on cloud platforms such as AWS, Azure, and Google Cloud.
In simple words, Terraform automates cloud infrastructure creation, making deployments faster, consistent, and easy to manage.
