A while ago I wrote a tool to convert flat disk images (which we commonly call dd images) to VMWare .vmdk disk images (the original blog post on the tool, called dd2vmdk is posted here). I have in the mean time ceased development of it, but despite its relatively archaic nature, some still find it of use.
Today I relocated hosting of it to Google's new cloud web application service, Google App Engine. My motivations to do this were to reduce adminitrative burden, to eliminate server costs, and to increase long term availability (the Java App Engine is Beta, so there might be some short term availability issues).
The relocation took roughly one hour of my time, was dead simple, and required no code modification, just the simple addition of a new text configuration file.
