Technical Requirements

In practice, you'll need at least one VM as a control machine, or you can use your workstation running Linux or Windows Subsystem for Linux (WSL). Along with this, we need a node, which needs to be an Azure VM. However, in order to provide a better explanation, we've deployed three nodes. If you have budget constraints in your Azure subscription, feel free to proceed with one node. It doesn't matter which Linux distribution you're using. The examples in this section, to orchestrate the node, are for an Ubuntu node, but it's easy to translate them to other distributions.

In this chapter, multiple orchestration tools are explored. For every tool, you'll need a clean environment. So, when you are finished with the Ansible section in this chapter, remove the VMs and deploy new ones before going into Terraform.
