Creating and managing infrastructure resources in Terraform involves several key steps:

1. Define the resource: The first step is to define the resource you want to create. You do this in your Terraform configuration file. This involves specifying the resource type, configuration parameters, and any dependencies on other resources.
2. Plan the changes: Once the resource is defined, you can use the terraform plan command to generate an execution plan that shows the changes that Terraform will make to the infrastructure to create or update the resource. Terraform takes the current state of the infrastructure into account. Terraform evaluates any existing resources that the changes may affect when it generates the plan.
3. Apply the changes: After reviewing the execution plan, you can use the terraform apply command to apply the changes and create or update the resource. Terraform automatically manages dependencies between resources and ensures it creates or updates them in the correct order.
4. Manage the state: As you create and update resources, Terraform maintains a state file. Specifically, this file tracks the current state of your infrastructure. Furthermore, Terraform uses this state file to manage resources over time and ensure they remain in the desired state.
5. Destroy resources: If you no longer need a resource, you can use the terraform destroy command to remove it from the infrastructure. Terraform automatically manages the dependencies between resources and removes them in the correct order.

Together, these steps form the basic workflow for creating and managing infrastructure resources in Terraform. As you continue working with Terraform, you’ll gradually start using advanced features such as variables, modules, and outputs. In turn, these tools help you create and manage complex infrastructure resources more efficiently and effectively.
