How much is that app you run in Azure? Or Amazon Web Services, Google, Rackspace or other cloud computing platform? As cloud app solutions fragment, with compute, storage, analytics and other services running in clouds from various providers with different pricing structures, getting a grip on the actual cost of cloud computing is no easy task. Yet, it can be done. Combine carefully chosen services with a long-term commitment and it's possible to achieve savings of as much as 74%. Like the 55-year-old song says, you better shop around.
