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)

Private Cloud: Elastic or a Hair Ball of Rubber?

Is your private cloud elastic, or just a tightly wrapped ball of rubber. One of the essential characteristics defined by NIST for cloud computing is “Rapid Elasticity.”  I blogged about Workload Elasticity Profiles in a previous post , but in the war between private and public cloud, people question whether you can actually unleash the elasticity from that ball of rubber bands. “Can a private cloud can be elastic?” To answer the question first need to understand elasticity in the cloud. A simple definition is the ability to “scale-up”  & “scale down” capacity automatically base...

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)
