The boss called, “What’s our PUE?”

Do you know your PUE?

PUE stands for Power Usage Effectiveness and it is rapidly becoming the number to know. In the past, datacenter managers were simply asked to provide enough space, power and cooling to support the IT equipment. Now, the same managers are being asked to do it efficiently. PUE can be a helpful benchmark.

Introduced by the Green Grid, PUE is a measure of efficiency. It is defined as: the total facility power consumed divided by the total IT equipment power consumed. The total facility power is measured...

Cloud-Oriented Architecture and the Internet of Things

Quick quiz for all you Cloud aficionados out there: what’s missing from the NIST definition of Cloud Computing? To make this challenge easy for you, here’s the definition: “Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management...

How WAN optimisation can improve your network stability

As data volumes continue to swell, organisations are continuously faced with the challenge of optimising their underlying network infrastructure in order to support the increasing flow of traffic.  Virtualisation, cloud computing, and Virtual Desktop Infrastructures (VDIs) deliver enormous management and costs savings, however, these benefits can easily be lost if application performance hampers end user productivity or backend processes, as often happens when applica­tions are delivered...

Hypothermic Cloud Infrastructure: Maintaining the Blood Flow to Tier 1 & 2 Apps

A particular sore spot since the beginning of the rise of cloud infrastructures, even the advent of utility computing is this: how do you forecast and pay for resources and justify costs for problems you don’t have yet? After all, the entire premise behind funding the acquisition of compute resources is that you are solving an already identified need (problem) which you then attach a cost and an ROIto in order to convince...

Using a cloud service to collect information on European cloud infrastructure services

The public cloud infrastructure as a service market is developing quickly, also in Europe. Over the past months we saw the number of international IaaS providers setting up shop in Europe increase, while also several European based providers launched new or upgraded offerings. To keep a finger on the pulse of developments we, started as part of the European Cloud IaaS coverage at Gartner surveying pan-European providers of Public Cloud Infrastructure as a Service . We are now extending the invite to participate in...

The Cloud’s Tipping Point

I always enjoy hearing from those of you who have come to the conclusion that Cloud computing will not work, and decided you will not be developing plans to shift your business to the Cloud.

Sometimes the analysis is sound. More often than not, it omits key variables.

Perhaps you relied too much on vendor input for key variables in your analysis, or on your own in-house staff that may not necessarily have the skills, experience, or vested interest in such analysis. After all, how often do they undertake such...

Microsoft’s Big Easy: An Easy Way to Earn Some Extra Money

Just as apple picking, raking leaves, and football are reminders of fall, Microsoft’s end-of-year Big Easy Promotion is a reminder about how to obtain some extra subsidy dollars to put aside for future purchases.   Yes that’s correct, the Big Easy is back for another go round, and I know you’re excited.  

You may be asking, what are you talking about?  Did you say Microsoft and promotion?  That’s like saying oil and vinegar, Athens and Sparta, Sox and...

Power Over Ethernet, PoE Plus and the Weather Channel

In light of the recent weather conditions, I thought I would write up a short take for Journey to the Cloud on Power over Ethernet (PoE).  Over the last decade there have been several variations of PoE – starting with the proprietary (heard this story before) and moving to a standards-based solution.  This doesn’t mean that the confusion has gone away.  

The original standards-based PoE was classified under the 802.3af specification.  These...

It’s Not a Disaster Recovery Plan If You Don’t Test It

There’s a fine story by Jacob Gsoedl over at SearchDisasterRecovery.com called, “Disaster recovery in the cloud explained” that makes for good reading.

Gsoedl provides a good overview of matters. I would like amplify one topic that I think deserves more emphasis than Gsoedl provides – testing.

As one of our customers recently put it to me, “You don’t actually have a DR plan if you...

China Telecom: cloud strategy set for 2012

China Telecom is the latest enterprise to announce its cloud strategy for 2012 with plans to launch esurfing cloud devices and storage products next year.

The telecom operator first established a cloud project team back in 2009 and has since completed testing in several major cities including Shanghai, Guangdong, Guangxi and Jiangxi and has a data centre as the core for the scale development of cloud computing. At the beginning of 2011, China Telecom launched a project to promote the access of optical fiber network...

Market Forecast: The Future is Already Here – It’s Just Not Evenly Distributed

The prescient quote by William Gibson aptly describes the worldwide Software as a Service (SaaS) market today, especially in the enterprise.

Global adoption and growth of SaaS within enterprises is unevenly distributed yet growing rapidly.  One...

VMworld and The Toughest Cloud Management Question

Last week at VMworld we asked a secret shopper to visit all the major cloud management vendors (BMC, CA, HP, IBM, and CA Nimsoft) and ask the Toughest Cloud Management Question.

VMworld is a great place to do this. Because the attendees are very smart and experienced and the people working the vendor demonstration stations know their products very well.
