Open Source Summit Europe 2024

IT infrastructure is all over the place: Cloud VPC's, edge servers, data centers, office networks, and more. Much of it exists on private networks or behind routers and firewalls. IT administrators are often tasked with making these resources available over the internet to employees or remote servers that are elsewhere on earth. In this tutorial, we'll use just a couple of VM's running Linux and WireGuard to set up a minimal, secure, and easily-maintainable remote access system. We'll demonstrate with a fictional business that has a physical office, uses the cloud, and has remote IT staff, an extremely common scenario. We'll walk attendees through: 1. How to set up secure access to the office network from the remote staffs' workstations. 2. How to establish access to a cloud VPC from servers in the office network. 3. How to account for corporate firewalls and other common networking challenges. By the end of this tutorial, attendees will have a good understanding of how they can use Linux and WireGuard in common IT networking scenarios.
