A wiki engine is the software that a wiki runs on for content and collaboration. A wiki engine operates in the cloud, so everything is done live, simultaneously, on the web. In short, the wiki engine powers the wiki to serve knowledge like an online encyclopedia. It's like a content management system for a website, but open to collaboration and knowledge sharing.

The wiki engine for SitesWiki is built on Google infrastructure. Google servers provide safe, reliable and fast performance, so they make perfect candidates for providing a wiki as a knowledge base. A wiki isn't complicated or cumbersome, so it takes virtually no space or bandwidth to run as a Google application.
