Going Green with Virtual Desktops

Everyone is talking about Green IT these days, and virtualization is a popular way to save money and reduce your environmental impact at the same time. Many companies have already discovered the benefits of virtualizing their servers, so the natural progression is to begin looking at virtualizing their desktops, as well.

There are several environmental benefits to using virtual desktops, but it all depends on the type of approach—whether you’re using server-based (VDI) or client-based virtual desktops. In the past, we have blogged about the shortcomings of VDI, such as cost and lack of offline support. From a Green angle, the problem with VDI is the huge datacenter infrastructure it requires, and more servers mean more space, increased power consumption, and increased cooling costs. The additional servers required by VDI more than offset any green savings you might see, and as a result, VDI is actually less Earth-friendly than traditional desktops. In contrast, a client-based solution (like MokaFive) requires no additional datacenter infrastructure.

Let’s compare the green impact of MokaFive vs. VDI. Gartner predicts that 49 million endpoints will be virtualized by 2013. Let's assume 30% will be laptops and remaining will be desktops. Based on those assumptions if all of those desktops were virtualized using MokaFive (instead of VDI), we would prevent 7.8 million metric tons of CO2 emissions each year—that’s the equivalent of taking 1.4 million cars off the road per year!

Another environmental benefit of client-based virtual desktops is the need for fewer machines. Virtualization allows you to use existing machines for multiple purposes: for example, an employee can use the same laptop for home and work. As a result, you can avoid the carbon footprint of an additional machine, including the energy and cooling it requires.

In addition, telecommuting is growing in popularity, and virtual desktops are helping to drive that trend. With centralized management, IT can easily support remote workers’ desktops, and employees have the flexibility of accessing their corporate desktop anytime, from any machine. Remote workers are environmentally friendly, too: they take cars off the road, and they save on office emissions (consider the space, energy, and cooling that each cubicle requires).

Desktop virtualization is a great way to reduce your IT costs and help save the environment at the same time. Just keep in mind that the type of virtualization approach makes a big difference, and client-based virtual desktops are by far the greenest option.

Learnings from our CIO Summit

Last month, we hosted our first quarterly CIO summit session that was attended by several CIOs representing some of the largest organizations in the US. The goal of this session was to investigate the priorities and the associated drivers for end-user computing within these large organizations. Over the course of a terrific power packed discussion, several themes emerged - one of which struck us as very distinctive.

We were expecting the usual themes around cost and control to emerge when, right at the beginning, one of the CIOs of a leading services firm said, “Look, it is not about control. IT doesn’t want to control; we just want to deliver enterprise value at the lowest possible cost, ensuring that every user is productive.” Quite a profound statement. Which brings us to the question, “Why are IT conversations always peppered with the word control?”

Upon further discussion, the answer became clear. The CIOs want to enable user productivity at the lowest cost and risk to the business. In the past, the only way to achieve a reliable, secure desktop was through lockdown and control. But over the years in many organizations, “control” has become the primary objective which, in turn, has lead to myopic decision making.

A number of influences seem to be changing this trend. One reason is that IT is required to support new business initiatives, which cannot be supported using traditional models. As the CIO for a large healthcare firm put it, “I have to enable new work models including teleworking and outsourcing. We hire talent where we get it and do not worry whether it is in the corporate location or not. These users need a secure, reliable working environment at their home, on the go, right at their fingertips at all times.” Second, there are finally a number of solutions now that can enable an IT organization to provide user flexibility without additional cost or risk penalty, so you don’t need to control and lockdown the user. In fact, client- based virtual desktop management solutions like MokaFive can significantly drive the cost and the risks down by enabling single image management across corporate and employee owned assets. (More elaboration in subsequent blog posts).

Another alternative that is commonly considered is VDI. Almost all the CIOs had investigated or were investigating VDI. But they found VDI to be too expensive, too complex, and most importantly, too restrictive for their users. This seems to be a growing sentiment and is reflected well in this article by Randy Eckel . We will explore more of the CIO comments and feedback in upcoming blogs.
