If you have done any work with Azure VMs or have gone through some of our Microsoft Learn content, you may be familiar with some of the options you have to connect to your Linux VM and we cover a few of the options in the lab. One of the easiest ways to get started is to assign a public IP, open inbound access to port 22 on your VM, and access the VM using SSH. This will certainly get the job done, but what if you needed to securely connect to your VM without exposing it to the internet?

Tailscale has excellent documentation on what it is and how it works. I highly recommend you visit their website to learn about what makes them special. At a high-level, Tailscale provides a peer-to-peer mesh VPN network that allows your devices to be added to a private network and be accessible from anywhere in the world. The devices that you add to your private network communicate with each other over an encrypted point-to-point connection which uses the open source WireGuard protocol. Their solution offers a "coordination" server (managed by Tailscale) which acts as a control plane that allows nodes (your devices) on your private network to share metadata needed to establish network connections.
With the application installed, open it and go through the configuration wizard and proceed to "Sign in to your network" which is essentially signing into tailscale.com via web browser.
