The fishing problem for public cloud companies


The fishing problem for public cloud companies

What is a public cloud really?It’s a modern virtualized data center paid for “as a service.” It’s really nothing technologically different. Amazon, Google and others offer the same thing that an internal modern virtualized data center could offer, but just as OPEX (operating costs) instead of CAPEX (capital costs). The theory is that the economies of scale of those public cloud companies will drive down costs that can be passed on to customers. I take issue with this theory for large enterprise customers.

There may or may not be some savings to be had for large enterprise customers in the public cloud, but if there is, it won’t be much. Here’s my version of the cost curve at a per-user basis:

Cost Curve

That big dot in my opinion is about 2,500 users. So the cost per user is high when the user count is low, but is driven down as the user count grows and the economies of scale kick in. Granted, this is my theory. But in my experience in architecting solutions, at about 2,500 users, you have the ability to really use virtualization in a modern data center and anything above that is more about designing management controls, which don’t bear nearly the cost savings that virtualization achieves.

In fact, most data centers could see an uptick in cost as their user counts get higher and higher. Anyone will tell you that too big can become just as bad as too small. Why do we think for a minute that public cloud companies are going to avoid this while trying to manage mega-data centers? 

It’s crazy to focus on the big fish anyway. There are many smaller companies and organizations out there that will see tremendous cost savings and become hardcore believers in cloud computing as the adoption rate climbs. I looked up via the census the percentage of companies that have fewer than 2,500 employees and the number was a staggering 97 percent of all companies. That’s a cash cow for public cloud companies, and we haven’t even talked about individuals who don’t have to be employed to want to use public cloud services.

In fact, I think that it’s not only a mistake to not focus on smaller companies and government agencies, I think it is a mistake to even allow the larger IT organizations to become customers. It’s more likely that they will become disgruntled customers over time as they realize they aren’t saving as much as advertised and have lost control of their own IT, adding security and information assurance problems to boot. Why risk the public black eye like Google got when NOAA Cloud Computing Program Manager Stephan Leeb slammed them for not working with the agency to resolve ongoing security and information assurance issues on NOAA’s Gmail contract?
