How to benchmark data center energy costs

How to benchmark data center energy costs: "One such method of measuring energy efficiency, developed recently by the Uptime Institute, a data center research organization, is corporate average data center efficiency (CADE). This calculation multiplies the efficiency of an organization's technology by the efficiency of the physical facility."

8 Predictions for Enterprise Web 2.0 in 2009 | Enterprise Web 2.0 | ZDNet.com

8 Predictions for Enterprise Web 2.0 in 2009 | Enterprise Web 2.0 | ZDNet.com: "3. Cloud computing will remain one of the biggest new Internet developments. The cloud computing story, as compelling as it is today for many situations, will only get larger in 2009. While the some of the bloom may be lost off the rose as some of the complexities and risks surface in early pilot projects, the cloud computing industry as a whole will grow in leaps and bounds as organizations seek to cut costs, manage growth/shrinkage, and shorten time to market. Expect major new products from the big existing players such as Amazon and Force.com as well as new entries from big firms and startups alike."

Possible Cloud Monitoring Tools | IT Management and Cloud Blog

Possible Cloud Monitoring Tools | IT Management and Cloud Blog: "Nagios
Most prevalent open source monitoring product.
Hyperic
At this point they are leading the pack with the most work done with (Amazon, Rackspace, and Mosso).
Zenoss
Not many cloud stories yet. Very sound monitoring tool.
Zabbix
I have used this product before and it is a solid tool. I am not sure if it’s a good play in the clouds. However it is written in C and might be better suited for performance (ala clouds).
OpenNMS
I need to research.
Ganglia
Very prevalent in the grid space. Might make a great candidate for cloud monitoring.
Collectd
Rightscale uses it as their monitoring tool. They seem to be making all the right moves, who am I to argue.
Ntop
Written in C. Might be a good tool for the cloud.

Finding distinction in 'infrastructure as a service' | The Wisdom of Clouds - CNET News

Finding distinction in 'infrastructure as a service' | The Wisdom of Clouds - CNET News

To briefly recap the cloud market for context, commercial cloud computing has traditionally been seen as consisting of three distinct offerings:


software as a service (SaaS): Complete application systems delivered over the Internet on some form of "on-demand" billing system. Examples include Salesforce.com, WebEx, and Workday.
platform as a service (PaaS): Development platforms and middleware systems hosted by the vendor, allowing developers to simply code and deploy without directly interacting with underlying infrastructure. Examples include Google AppEngine, Microsoft Azure, and Force.com.
infrastructure as a service (IaaS): Raw infrastructure, such as servers and storage, is provided from the vendor premises directly as an on-demand service. Examples include Amazon Web Services, GoGrid, and Flexiscale.

What Randy is arguing, however, is that there is a clear distinction between the service ecosystem approach of Amazon Web Services (which he calls an infrastructure Web service) and a more utilitarian infrastructure-focused cloud service such as the ones many of the hosting companies-turned-cloud providers have produced, including GoGrid, Flexiscale, and Rackspace CloudServers. He calls those companies providers of "cloud centers."

Engineering Windows 7 : Windows 7 Energy Efficiency

Engineering Windows 7 : Windows 7 Energy Efficiency: "The base hardware platform is really dictated by the system manufacturer. The customer gets the ultimate choice when they buy a system—the customer can buy a system with ultra-efficient hardware components or can buy a system with components that favor performance over power consumption. There are desktop and mobile PCs in all kinds of form factors, with varying capabilities and power consumption levels. Some mobile PCs have a normal 3 or 6-cell battery, while others have an extended 9-cell battery or another external battery that can be added to the computer. The challenge for Windows is to be energy efficient across the wide range of hardware in the Windows ecosystem. Looking at a modern laptop, here is where the power goes:

Frequently Asked Questions - Mininova

Frequently Asked Questions - Mininova: "Mininova is entirely written by us (the admins) in PHP. It doesn't use any template or other system, because they are all too slow. Mininova is running on 4 webservers, 4 database servers, 2 search servers, one NFS server, and one load balancer (plus 5 additional servers for the forum, blog and the ads).

We use LightTPD as webserver because with a lot of hits it's just faster than Apache (which we used to run). Mininova makes heavy use of XCache to cache compiled PHP scripts. XCache is also used to cache blocks of HTML which are generated using information from the database that doesn't change very often or which are requested very often. As DBMS we use MySQL because it's free and fast."

The systems provide business intelligence and allow executives to make better decisions based on events analysis. IBM was interested in taking over ILOG as IBM felt the merger would allow businesses to process and monitor more complex events with the ILOG systems. More companies are beginning to enter the events planning space, including Oracle and Streambase."

Multivariate normal distribution - Wikipedia, the free encyclopedia

Multivariate normal distribution - Wikipedia, the free encyclopedia: "Multivariate normality tests

Multivariate normality tests check a given set of data for similarity to the multivariate normal distribution. The null hypothesis is that the data set is similar to the normal distribution, therefore a sufficiently small p-value indicates non-normal data. Multivariate normality tests include the Cox-Small test [3] and Smith and Jain's adaptation [4] of the Friedman-Rafsky test."
