The course is prepared for anyone who manages cloud infrastructure and does not want to prepare it manually. Terraform is a tool for unified infrastructure management in cloud services. It can prepare, modify, or drop a cloud or local infrastructure - including dependencies between components. One universal tool can be used to manage the infrastructure in different cloud environments. Packer is a tool used to prepare images of virtual machines for Terraform - again for different cloud providers and using various configuration tools - from Ansible to Zsh scripts. We will use Terraform and Packer during the training on practical examples.

Audience

Cloud administrators which want to move forward to their automation even more cloud environments.

We went to the course with basic knowledge of Terraform, Jirka adapted perfectly to our level of knowledge and we did not waste time with complete basics. I liked that most of the course was purely practical in perfectly prepared labs. We received answers to all our questions beyond the course. I definitely recommend it to anyone who wants to penetrate more into IaC. Daniel Vašek, Mall.cz
