Virtualization Drives Higher IT Efficiency and Lower Maintenance There is an ever increasing demand to boost IT efficiency and reduce costs which has led to much innovation in this field. Perhaps the single most important breakthrough in this regard has been the widespread availability and adoption of virtualization technology. Virtualization refers to the provision of IT resources – hardware platform, operating system, storage, networking etc. that are ‘virtual’ rather than actual physical devices. Instead of weeks, new virtual resources can be up and running within minutes resulting in huge savings in time. Further, these virtual resources enable huge savings in costs while simplifying IT operations and maintenance.

Cloud Computing: Determining The Cost Of The Cloud – Part 3 Infrastructure as a Service (IaaS) This service model enables user organizations to forgo deployment of new datacenter equipment to handle growing operational needs. Rather, the business obtains needed IT infrastructure – servers, security, storage, networks, etc. – from a cloud services provider, often via a self-service catalog. While a user company can run applications, databases, operating systems and other software on top of its selected infrastructure, it has no direct control over or access to those machines. The cloud service provider manages the infrastructure, including any scaling up or

Types of Cloud and their relevance Continued From Part 1… There are three relevant types of clouds: Private (internal or vendor-hosted), Public (external), and Hybrid (mixed). Each cloud infrastructure has unique characteristics that can meet business objectives. Enterprise Private Cloud A private cloud enables enterprises to implement cloud computing solution at either their own site or at service provider’s datacenter. Enterprises are implementing a private cloud within areas of their infrastructure in which a cloud model makes the most sense. A private cloud provides many of the benefits of cloud computing without the loss of control and security risks associated
Virtualization and the emergence of private cloud computing provide today’s organizations with powerful new ways to provide business groups with the computing and infrastructure resources they need—more quickly and cost-effectively than ever before. For many business groups, virtual machines (VMs) can provide precisely the resources they require without those groups having to jump through the hoops associated with gaining access to the same resources delivered through a physical infrastructure. Both the IT team and the business organization benefit from the absence of physical infrastructure, the elimination of long approval and purchasing cycles, and the speed with which virtual resources can
