I have written a relatively simple Java App Engine application which I would like to be able to port to another cloud provider.

I am using the JDO datastore API so I think my data handling should be portable to other backends as listed here: http://www.datanucleus.org/products/accessplatform/index.html

I would ideally like to deploy my application onto EC2 with minimal code changes. What is my best approach?

Note: I am aware of the http://code.google.com/p/appscale/ project but I want to avoid using this as it doesn’t look like they are updating very often.

    I managed to get my application working on EC2 using the following components.

    • Tomcat 7
    • Datanucelus
    • HBase

    I had to manually create a table in HBase for each of my data classes but was able to configure Datanucleus to auto create the columns.

    I also had to change my primary key value generation strategy from identity to increment as per this table of supported features.
