This course is designed to help learners obtain the Terraform Associate certification from HashiCorp. 

You’ve likely picked up this course because you dabbled in Terraform as a hobbyist or in a
development environment, and you’re excited about the possibilities of deploying Infrastructure 
as Code (IaC). It will enable you to sharpen your skills and prove your knowledge with a certification from HashiCorp. Terraform is an amazing tool to deploy Infrastructure as Code in a cloud-agnostic way. We’re excited to share our accumulated knowledge with you through this course.

# Purpose of the `ter`aform apply` command
The `terraform apply` command executes changes to the actual environment to align it with the desired state expressed by the configuration or from the execution plan generated by `terraform plan`.



# Creation of an execution plan

By default, `terraform apply` looks for a Terraform configuration in the current working directory and creates an execution plan based on the desired state and the actual environment. The execution plan is presented to the user for approval. Once the user approves the execution plan, the changes are applied to the actual environment, and the state data is updated.

If a saved execution plan is submitted to `terraform apply`, it skips the execution plan generation and approval steps and moves directly to changing the actual environment and state data.

Strictly speaking, we don’t have to run `terraform plan` before `terraform apply`. Skipping the planning stage might be justified when running Terraform manually outside of a team setting. If we start to automate Terraform runs or collaborate with a team, then it’s advised to always run `terraform plan` first and save the execution plan to a file.
