Since posting this question, I have been reading through a few presentation and youtube videos. So far I have gathered the following: Option 1: Use a customized solution stack from a cloud vendor like Amazon, Azure. To quickly bootstrap, there are also consulting firms that specialize in one of these cloud solutions. Option 2: Build using open-source stacks. Couple of interesting architectures are : SMACK , Lambda. Any help that you could provide in pointing to the right links or just notes from which I could derive an reference architecture will be greatly appreciated.
