jfruh writes "Practically since OpenStack was started there has been discussion about whether it should fully support Amazon Web Services' APIs. Doing so would make it easy to port applications between an OpenStack cloud and AWS. It would also let businesses easily build hybrid apps that run internally on an OpenStack cloud and on AWS. Cloudscaling's Randy Bias has been vocal about his support of fidelity with AWS. He argues that there's no hope for OpenStack in the public cloud market so it would do well to support interoperability with AWS and Google Compute Engine if it wants to hold on to the private cloud market. It's true that interoperability with AWS would be good for OpenStack in the private cloud market. But it's easier said than done."
