VPN’s have traditionally been slow, complex and hard to set up and configure. That all changed several years ago when Wireguard was officially merged into the mainline Linux kernel ([src](https://arstechnica.com/gadgets/2020/03/wireguard-vpn-makes-it-to-1-0-0-and-into-the-next-linux-kernel/)). I won’t go over all the reasons for why you should want to use Wireguard in this article, instead I will be focusing on just how easy it is to set up and configure.
For this tutorial we will be using Terraform to stand up a Digital Ocean droplet and then install Wireguard onto that. The Digital Ocean droplet will be acting as our “server” in this example and we will be using our own computer as the “client”. Of course, you don’t have to use Terraform, you just need a Linux box to install Wireguard on. You can find the code for this tutorial on my personal Git server [here](https://git.hackanooga.com/mikeconrad/wireguard-terraform-digitalocean).
