It's time to have some fun. Sure, tell your colleagues or your family that you're doing research, experimenting with some new tech—because that is what we'll be doing—but just don't let them see you playing Minecraft!
Here's the scenario: You're organizing a full-day Minecraft class for local STEM students. You need to run your own Minecraft servers to ensure a kid-friendly multiplayer environment, restricted only to your students. One server won't be enough, so you'll run two servers simultaneously, expecting your load balancer to handle sending students to Server A or Server B, depending on the load.
