Course Description:

Hashicorp's Terraform is one of the most popular infrastructure provisioning tools in the market, supporting multiple cloud providers (AWS, Azure, GCP, Oracle, etc.). This course enables students to use Terraform for defining infrastructure as code and automating infrastructure deployment - improving operational efficiency, lowering administrative overhead, and reducing the chance of human error.

What will you learn:

At the end of the course, students will have a firm understanding of Terraform basics and will be able to:

• Write Terraform configuration files
• Understand how Terraform integrates infrastructure sources
• Manage infrastructure environments

Target audience:

This course is for system administrators wishing to use Terraform to automate cloud-based infrastructure deployment.

Note: Every student has assigned to him his own virtual lab environment setup.

Prerequisites:

• familiarity with the Linux command line (commands, arguments, variables, working with files and directories, using text editors)
• basic TCP/IP networking (IP addressing, subnets, etc.)
