The object of Deltacloud is to open up competition and choice in the cloud market, just as Red Hat Linux did in the hardware market, eliminating the switching cost of investing in a new stack of proprietary offerings and allowing cloud users to invest the savings into conducting application development that truly differentiates them.
Thirdly, converged infrastructures for cloud could get a boost through tighter integration between the hardware and OS, thanks to performance optimizations, better resource automation, and fault management throughout the stack.
