Terraform is an open-source tool mostly used by DevOps, as it provides the facility to build, manage, and update resources on cloud platforms by coding, AWS is an advanced network partner of Terraform. Terraform’s state allows its users to track the changes in their resources through the development process.
This post will provide a procedural guide to install Terraform in the EC2 instance, even including the steps to create an EC2 instance first.
