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)

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...

Will the Channel Disrupt the Cloud?

James Urquhart wrote an interesting article today in his Wisdom in the Clouds blog on CNET about how cloud changes the customer, vendor relationship. In the article he states: "In cloud, your traditional technology suppliers are now interfacing directly with the customer, and the channel's "value add" of customer relationship management, technology delivery, and solutions development is being seriously threatened." Having worked for enterprise customers and vendors for the last 20 years, I have to say many companies have a direct relationship with their technology providers.  I ... (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...
