Iac - Terraform
Terraform is an open-source tool for defining, provisioning, and managing infrastructure as code. It works with various infrastructure providers, including popular cloud providers like AWS, Azure, and Google Cloud, as well as on-premises providers like VMware and OpenStack.
Terraform’s core feature is its ability to create and manage infrastructure resources predictably. By defining infrastructure as code, users can version, review, collaborate on changes, and easily track changes and roll back to a previous state.
Terraform also offers advanced features like remote state management, workspaces, and modules, which organize and reuse code and manage infrastructure state.
Terraform has a large, active community that creates and shares custom modules and providers, making it easy to manage additional resources and services without writing custom code.
In the process of initializing the project, Terraform will parse the *.tf files in the directory and load the relevant

You may now begin working with Terraform. Try running "terraform plan" to see any changes that are required for your infrastructure. All Terraform commands should now work. If you ever set or change modules or backend configuration for Terraform, rerun this command to reinitialize your working directory. If you forget, other commands will detect it and remind you to do so if necessary.

Overall, Terraform is a powerful tool for teams looking to automate and manage their infrastructure consistently and predictably across multiple providers.
