AWS (Amazon Web Service) including S3 and EC2 had downed again (See here)

We may have a need of balancing our services over the several EC2 clones.
Fortunately, there have already been several computing clouds on the Internet.
But there are no compatibilities between them.
Their interfaces should be standardized.
I think that the spec would become similar to EC2 because of its accumulated experiences.

BTW, I can't stop recalling the story of Permutation City of Egan.
