It is still very difficult for a traditional enterprise to find a path from current infrastructure deployment models to a pure cloud architecture. I have discussed many times before that a very tangible "Trigger Event" needs to be identified that will get the gears in motion. The recipe for this change, often needs a second ingredient which is readily accessible technology that allows IT to create solutions with minimal upfront investment (i.e ShadowIT). This "Trigger Event" cannot be described in abstract terms like "ROI" or "TCO" and definiely not business strategy terms like "agility" or "time-2-market". These are all good labels to frame the beginning of the discussion at executive levels, but where the rubber meets the road is real applications providing real intelligence or new services. The problem is most enterprises have a large legacy environment of applica... (more)

It’s War: Public vs. Private Cloud Computing

There is a common question that almost universally arises when people discuss cloud computing. The question came up in a webinar I did with Rackspace last week. It was featured in regular conversation at Cloud Connect and then again on Twitter from Adrian Cockcroft. The question was framed like; "There is no technical reason for private cloud, it's all $, FUD, and internal politics. Discuss." - Adrian Cockcroft, Do you think there is a need for private clouds (vs. public)? Important to note we are not talking whether they should run on a cloud. This argument only applies to applic... (more)

AWS and the Public Cloud Market

The public cloud market is dominated by a 800 pound gorilla. We assume its 800 pounds and not 2000 pounds. It could even be 100 pounds or maybe not a gorilla, but an elephant of a paler color. There is no public information indicating its true size, revenue or performance. Let’s assume based on the marketing information it's 800 pounds and a gorilla. The recent release of the dedicated instance feature within Amazon Web Services has shone a spotlight on a possible future of public cloud. A proof point that cloud and the traditional hosting model might exist on the same continuum... (more)

ROI: Justifying the Cloud

A classic use of ROI or its twin TCO is in the Microsoft Economics of the Cloud, Nov 2010 paper. The conclusion is you can improve TCO by up to 80% by using applications in public cloud versus on-premise deployment. The basics of the calculation being: improved utilization (10% to 90%) enabled by virtualization/consolidation & elasticity the economies (power, operations, HW purchase etc..) of scale of multi-tenant cloud scale hosting Given most costs in a DC are directly linked to the amount of infrastructure deployed, then improving utilization from 10% to 90% sounds like the pri...
