I think its still useful to have both, although I have a feeling that
something like the 'AWSOME' conversion layer from EC2 might still be a
pretty useful project to have to allow for a robust EC2 api which has a
dedicated group of people to support it. Never was quite sure what
happened to that project.
I might even take this further and propose that the nova-api binary itself
should/could be this 'conversion layer' as a separate project and then
allowing nova (the rest of the binaries) to be everything under said API
(the MQ would then be more of nova's 'exposed' API). Then the exposed WS
api can be whatever is best at that layer, whether it be ec2 or the native
But as for which one should be supported, I think this is an evolutionary
thing, whichever is most used and supported will be what openstack uses;
if that¹s the ec2 api or the native nova-api then so be it. Perhaps this
is another good reason for nova-api as its own project, let that battle be
fought in said project instead of having the nova project deal with that
