I m looking to write a Java (Groovy actually) web application that will need to talk to both AWS and Eucalyptus clouds for both compute and storage. So we re looking for a Java library that can talk to both.

I know that Eucalyptus is supposed to be AWS API compatible so anything that talks to AWS should be able to talk to Eucalyptus but that has not been my experience. I ve found some of the ec2 command line apps that should work with Eucalyptus but simply crash.

Here s what I m considering so far:

Do anyone have experience using any of these to talk to AWS and Eucalyptus? Are there any other similar APIs out there worth looking at?

Thanks

Answer 1

Since your doing Java/Groovy (Grails?) I would suggest adding CloudFoundry to your short list.

Answer 2

You might want to take a look at libcloud s Java version (original version is in Python): https://svn.apache.org/viewvc/incubator/libcloud/sandbox/java/trunk/. Its development seems to go quite fast and the whole thing looks quite promising.

Answer 3

I would suggest that you write up an API for your cloud engines for your needs, and then use a separate implementation for each backend you want. The reason for this - makes it mockable (hence testable).
