That we can access our data, even from remote locations with ease and in real time without any lag issues or delays at all! It's easy to use & it's very fast too! No more worries about server crashes since you don't have your hard disk space taken up by DB files.
You definitely need this app for every web developer/developer that builds websites using PHP frameworks which are hosted via Cloud providers like AWS, Google Apps etc.. I like that it's easy to spin up new servers, there are no long-term contracts or commitments so you can easily move them around if needed (which we do often). It takes some getting used too but once things start working they work pretty well without any issues at all! We've been able use this for years now with very little problems - our customers love how fast their apps launch compared other hosting providers in general which has made us more successful than ever before!!
