Following are the key features of Terraform:

• Infrastructure as Code: Terraform's high-level configuration language is used to describe your infrastructure in declarative configuration files that are human-readable. You may now generate a blueprint that you can edit, SHARE, and reuse.
• Execution Strategies: Before making any infrastructure modifications, Terraform develops an execution plan that describes what it will do and asks for your agreement. Before Terraform produces, upgrades, or DESTROYS infrastructure, you can evaluate the changes.
• Graph of Resources: Terraform develops or alters non-dependent resources while simultaneously building a resource graph. This allows Terraform to CONSTRUCT resources as quickly as possible while also providing you with more information about your infrastructure.
• Automation of Change: Terraform can automate the APPLICATION of COMPLEX changesets to your infrastructure with little to no human intervention. Terraform identifies what happened when you update configuration files and provides incremental execution plans that take dependencies into account.
