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 based on demand, and only pay for what is provisioned. The issue is not the technology you implement. The technology that powers the public cloud is the same technology available to power the private cloud at every level in the stack.  You can create a private cloud using all the same building ...

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)

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)

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...

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)
