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 applications and workloads that have already been determined to be a good fit for cloud. The second question is more easily answered as it alludes to diverse organizational requirements that are unable to be serviced by a commodity service, or the natural inertia of organizations to adopt new meth...

Big Data: Cloud's Killer App For the Internet of Things

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 "a... (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...

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...

The Importance of Many Clouds

Looking forward to the Redhat Summit this week in Boston with a theme of “Platform, Middleware, Virtualization, Cloud”. The cloud market is dominated by a lot of startups, with some goliath-size companies still waiting in the wings. Depending your point of view, they are either lumbering dinosaurs unaware of the next evolutionary shift, or if you are like me, I think they are poised to strike. If you believe enterprise adoption is the next wave of cloud adoption, then these organizations have huge salesforces with deep customer relationships and services organizations capable of ... (more)
