A few months back I started to look for hosting solutions for Unity Asset Server. I looked at a bunch of the top tier providers of Virtual Private Servers and eventually discovered that Amazon is running a special where you can run a micro instance EC2 for a year for free. I’ve been using it for over two months now and I’m super happy. There were a few gotchas in the otherwise simple setup process so I made a tutorial to help others navigate the process.

After the first year you are charged hourly, which still ends up being super reasonable, especially if you don’t leave it on 24/7. It would be sweet if someone could write an editor extension that interfaces with Amazon’s API so that users could start and suspend the server with a click of a button in Unity.
