Description: A resource plan in Terraform is a crucial document that outlines the resources to be created, modified, or destroyed during the execution of an ‘apply’ command. This plan serves as a roadmap that allows users to visualize the changes to be made to the infrastructure before they are executed. By running the ‘terraform plan’ command, a summary is generated that shows the differences between the current state of the infrastructure and the desired state defined in the Terraform configuration files. This includes the creation of new virtual machine instances, modifications to existing configurations, or the deletion of resources that are no longer needed. The resource plan not only helps prevent costly errors by providing a preview of the changes but also enables development and operations teams to collaborate more effectively by having a clear understanding of what will be implemented. Additionally, the plan can be reviewed and shared with other team members, fostering transparency and communication in the infrastructure management process.
