Why should we virtualize?
Every time we look at a virtualization opportunity within a data center, customers are often exposed to fear, uncertainty, and doubt. It is a new technology; it aggregates everything and poses a challenge, not only to the siloed environment but also the siloed mentality. As the convergence takes place inside the cores, the "people and process convergence" needs to happen as well. The benefits of virtualization are simply irresistible.
Virtualization is a golden opportunity for organizations to do a technology refresh, providing a means to deliver IT in variety of ways to a highly aspirational consumer. Another major opportunity is towards Corporate Social Environmental Responsibility (CSER), especially energy, which helps organizations reduce their carbon footprints. But still the biggest advantage is—it saves a lot of money!
It helps organizations to:
Smart meter power and energy consumption as against the siloed approach where everything is always "turned on"
Redeploy resources as and when the demand is generated
Reduce and even contain the risk and cost of legacy applications on legacy hardware, which can now run seamlessly on state-of-the-art hardware
Always be available—there is a growing demand for continuous availability without increasing costs, and virtualization can adequately address both, the pain and the pleasure here
There are a lot more arguments, but keeping the focus simple we can safely say that with virtualization you can increase your productivity while reducing costs of operations.
