Google Appengine

I thought I just had to upload a few log files to the server & then have some awesome graphs appear almost magically out of the box! Servers : "How do I get a server up and running?" There is a free trial for cloud based elastic stack. I signed up and got a 14 day free trial with 4 instance running on Google Clo
