Infrastructure as Code in Terraform

The course will focus on culture and principles that form a foundation for reliable processes of configuring, maintaining, and deploying various environments with Terraform. Practical tasks are combined with resource deployment in the AWS cloud. Hashicorp Terraform will be reviewed in detail: setting boundaries for its application, problems, and ways to solve it in various situations, as well as initial steps in building infrastructure and purposes of automation for its successful operation.

Each step in this course is supported by real-life cases, which allows trainees to immediately apply new knowledge and skills to real projects at any stage.

Upon completions of the course, trainees will be able to:

• Understand different models of infrastructure management;
• Create and support an infrastructure using code written in Terraform;
• Understand the benefits of automation;
• Test their solutions and guarantee successful implementation;
• Identify problems at any design stage.
