Create an Amazon AWS Account

LightSail is a very affordable (almost free depending on usage) cloud computing platform that is great for running TikiWiki for personal projects or small collaboration groups.
Another aspect of LightSail is that it is geared for easy to setup and maintenance with just the bare amount of features that you need to run a professional looking TikiWiki.
