Infrastructure as Code with Terraform

Infrastructure as Code with Terraform enables you to define, provision, and manage cloud infrastructure using code, making deployments consistent, repeatable, and scalable.

Duration 3 Days – 21 hrs

 

Overview

The Infrastructure as Code with Terraform Training Course is designed to provide participants with practical knowledge and hands-on skills in automating infrastructure provisioning using Terraform.

This course introduces Infrastructure as Code concepts, Terraform architecture, configuration language, providers, resources, variables, outputs, modules, state management, workspaces, remote backends, and collaboration workflows. Participants will learn how Terraform can be used to provision and manage cloud and on-premises infrastructure in a consistent, repeatable, and controlled manner.

The course also covers Terraform best practices, version control integration, CI/CD pipeline concepts, security considerations, governance, and policy-as-code principles. It is suitable for technical teams involved in cloud infrastructure, DevOps, automation, platform engineering, and infrastructure operations.
