Could EMC Become The Amdahl of Cloud Storage?

There is no doubt that EMC has shipped some Atmos storage since its introduction. Yes, EMC has Atmos. And the company claims that Atmos is specifically designed for the cloud. However, I believe that there are fundamental issues with the way EMC sells Atmos to customers. First of all, if Atmos is cloud storage, then it should be sold on a usage basis. Customers should be charged only for what they use–not for petabytes of capacity up front. After all, isn’t that the whole premise of cloud? Lowering your capital expenditures and shifting to a utility model? It makes me wonder if EMC is slowly becoming the Amdahl of Cloud Storage.
