Due to the cost hike introduced yesterday for Application Engine, it's gone from becoming an basically free hosting choice to a potentially too expensive one.

Consequently I must consider what my choices are for moving my Java/JDO application off Application Engine with a other hosting provider.

Because JDO abstracts the actual database layer, am i right that the couple of SQL (GQL) changes plus some minor configuration changes (appengine-web.xml) are that might be needed to maneuver with a other Java hosting platform?

And, next, the other Java hosting platforms provide a similar degree of performance for any lower cost compared to new Application Engine cost structure?

You can opt for a minimal or mid cost Xen VPS.
