Terraform

Terraform is an open-source Infrastructure as Code (IaC) tool developed by HashiCorp. It allows you to safely create, modify, and stop infrastructure, and version these operations just like any other code. Terraform can manage multiple cloud service providers (such as AWS, Azure, Google Cloud Platform, etc.), network devices, and other resources.

TrueWatch provides a Terraform Provider for managing TrueWatch resources. Users can define and write TrueWatch related resources through the Provider and manage them using the Terraform command-line tool.
