1. Datacenter Virtualization: Towards A Greener Computing Environment
The technological innovations, advent of cloud process and global business environment has together
given rise to the concept of virtualization. Hence, organizations in their attempt to go green look forward
to methods to enable virtualization across network, applications and systems.
Customers with their aspirations for a more technologically innovative environment demands that
enterprises are ready with the best of the breed application and the related IT infrastructure. This has led
to the development and deployment of data centers which cater the clients with top of the line
infrastructure, networked with security features, updated software applications with anywhere anytime
access. Dynamic market environments, competitive business objectives, the need for higher service levels
and budgetary limitations have paved way for datacenter virtualization.
Virtualization of data centers includes a range of activities that are aimed at creating a virtualized
computing environment. Implemented initially for better utilization of the available physical resources,
the focus today is on developing data centers that are dynamic, agile with services-oriented architectures.
Gartner estimates that data centers are accountable for nearly 0.5% of all global carbon emissions.
Further, with the growth in the demand for cloud solutions, will only see an increase in the amount of
energy required to power data centers. Datacenter virtualization will not only facilitate significant savings
on floor space and power, but also enable efficient sharing of server, storage and network resources while
reducing operating expenses. It empowers the IT department with tools for resource scheduling, data
protection, and disaster recovery.
Leading enterprises that provide datacenter hosting solutions work through a phased methodology to
provide cost-effective green datacenter solutions, which would also lend sustainability to the business
operations. As the first phase, these service providers assess energy usage and carbon footprint of the
existing datacenter environment. Further, through Gap analysis and feasibility study, they work towards
identification of transformational activities. With a detailed roadmap for green IT initiatives like
procurement, optimisation, recycling and resource planning the service providers completes the design
phase and enters the implementation phase wherein they implement specific technologies for datacenter
virtualization and IT infrastructure management.
