Customize an Azure Linux VM with Cloud-init

This hands-on lab will demonstrate how to create an automated startup configuration file to pass into VMs using cloud-init. **Cloud-init** is an open-source tool for Linux cloud VMs, which has native support in Azure. It is important to note that cloud-init configuration is NOT in the form of a shell script, but uses modules in YAML syntax, which can be a learning curve for those used to shell scripting. The lab's primary focus will concentrate on formatting our configuration file. Mastering cloud-init enables automation in VM configuration, which is essential for auto-scaling services such as VM Scale Sets.
