EnerNOC takes an integrated approach to energy management

I've written about energy management company EnerNOC in the demand response sense, based on the work that it is doing to help companies with generating capacity reduce their grid dependency in peak demand situations. (As a reminder, here's my post about how EnerNOC is working with a New York-based data center operator to help it make the most of situations where it could benefit financially from turning on its generators.

Improved insights and analysis from IT systems logs helps reduce complexity risks from virtualization

We seem to be at a tipping point in terms of everyone doing virtualization, or wanting to do it, or wanting to do even more. IT managers experimenting with virtualization are seeking to reduce costs, to improve the efficiency in use of their assets, or for using virtualization to address the issues they might have with energy cost, energy capacity or sometimes even space capacity in the data center. But the paybacks from virtualization can be lost or mitigated when management and complexity are not matched. Poorly run or mismanaged virtualized environments are a huge missed opportunity.

About that London Stock Exchange IT failure

The obvious lesson from the correlation between Microsoft's eagerness to brag about the performance and reliability of the system installed at the London Stock Exchange and it's actual performance and unreliability is that pride goeth before a fall - but the deeper lesson is that top management didn't do its job and should be held accountable.

No Government rules on packet throttling, blocking, colleague says on Capitol Hill

Colleague George Ou, who is not a proponent of most net neutrality regulations, stated his opinions before a Congressional staffer-panel on Network Management sponsored by iGrowthGlobal.That outfit, whose board is full of board members who have served in a similar capacity on the Pox on consumer rights that is the Progress & Freedom Foundation, a group that declares as part of its goal that:governments resist the temptation to regulate, tax and control.

Virtual labs and education

Yesterday, I asked for people to share their thoughts via a guest blog on virtualization in Ed Tech.   Guest blogger Erik Josowitz provided us with the following (thanks, Erik).  Feel free to talk back or submit your own guest blog with some specific experiences or implementation details. Virtualization is great tool but, like any Swiss-Army knife, success with it depends on the task at hand. One of the places that people get into trouble with virtualization is when they try to use out-of-the-box virtual infrastructure with non-technical audiences. Virtualization is a great solution but often is not a complete solution.In education we've frequently seen challenges that look like appropriate places to implement a virtualization solution, only to find that the end-result is not fully usable by the intended audience. One example is providing hands-on lab environments to support application training. Success in the workforce today depends on high-level application skills and there is no better way for students to attain those skills than through hands-on use of the software applications. Many educational institutions provide computer lab environments to help support their student population and provide access to necessary software applications. Many of these lab environments have become the source of IT management problems as they become virus-ridden, get subverted as distribution sites for pirated software or music, or just plain have the normal IT management issues associated with a shared resource in a public environment. For many institutions their student population brings with them their own PCs which solves one problem but creates another. The lab issues diminish but the problems of providing secure access to software (and software licenses) often takes its place.The answer, we've found, is virtual lab management - using virtualization to deliver secure computing environments as a shared resource. Virtual labs allow administrators to serve up a clean and unchangeable environment for each student - in the lab or on their own PC - on-demand. This makes it easy to provide access to applications that students either can't afford individually or that their home PCs cannot support. It makes it simple to track and monitor lab usage and to control the use of resources so that systems are not subverted into file servers. Virtual lab management sits on top of virtualization (from Microsoft or VMware) and tells it what to deliver and to who. It makes it easy for non-technical users to select the types of applications they need from a menu and to gain access to those environments without needing to understand virtualization, networking, hosts systems or anything about how it gets delivered. Best of all, virtual labs make it easy to manage capacity. By scheduling time in the lab environment the shared resource is managed for maximum utilization. If more capacity is needed it is simple to add additional resources to the system. The end-users simply see an increase in availability.Virtualization may not be a panacea for educational institutions, but for a subset of problems, a centralized virtual lab may enable technology administrators to focus their time and attention on enabling learning rather than administering systems.
