Course Description:

This course will provide an in-depth understanding of Terraform, a popular open-source infrastructure as code tool. DevOps engineers will learn how to use Terraform to create, manage and update infrastructure in a repeatable and scalable way. This course covers the core concepts of Terraform, including resource types, variables, modules, state management, and best practices.
