Terraform makes it extremely easy to deploy vm instances on multiple providers like CloudStack, OpenStack, AWS, Azure and more by describing your complete infrastructure as code. You describe you infrastructure in configuration files “*.tf” for a simple or complex applications or deployments. Terraform then takes that configuration and creates an execution plan so that you can see what it’s going to do before it does it. As the configuration changes, Terraform is able to determine what changed and create incremental execution plans which can be applied. And when you need to tear down the deployed services it’s as easy “terraform destroy”.
