Virtualization is a method of running multiple independent virtual servers and operating systems on a single physical computer. It is a way of maximizing physical resources to maximize the investment in hardware. Virtualization technology is a way of achieving higher server density. However, it does not actually increase total computing power; it decreases it slightly because of overhead. This slashes the majority of hardware acquisition and maintenance costs that can result in significant savings for any organization or company and maximize the ROI.

Virtualization is the perfect solution for applications that are meant for small-to medium-scale usage. Virtualization should not be used for high-performance critical applications where one or more servers need to be clustered together to meet performance requirements of a single application.

It is not at all advisable to put all of your critical servers into a single physical server. The easiest way to avoid this risk is to make sure that a single service isn't only residing on a single server rather they are available in 2 physical servers to gain complete redundancy. ...
... When a single physical server fails or needs servicing, the other virtual server on the other physical server would automatically pick up the slack. By straddling multiple physical servers, these critical services never need to be down because of a single hardware failure.

There are many players offering solution on virtualization and Cisco is the leader in server virtualizations who uses Cisco UCS (Unified Computing System). Cisco has different technologies achieve virtualization at different levels. This solution simplifies server virtualization through comprehensive, end-to-end management, including Applications, Operating system, Physical and virtual servers, Network and storage resources.

•The joint Cisco-VMware solution supports faster adoption of server virtualization across a broad range of applications.
•Cisco VN-Link and Red Hat Enterprise Virtualization (RHEV) technologies provide hardware-accelerated virtualized I/O benefits.
•Cisco Unified Computing System (UCS), running Microsoft Windows Server 2008 R2 Hyper-V, virtualizes Microsoft enterprise applications.

Using Cisco service profiles, each organization can deploy an infrastructure much more quickly, eliminating time-consuming and error-prone manual provisioning tasks. This solution leads to reduced total cost of ownership (TCO) and an increased return on investment (ROI).

The joint solution between Cisco and VMware is highly flexible, cost effective with optimum performance of the hardware platform. This uses a flexible resource pool to speedup the application deployment. Resource pools are also used for securing applications and improving its availability with fewer points of management thereby reducing the cost and eliminating barriers to virtualizing mission-critical applications. The Role- and policy-based management used by this solution manages better communication between administrative domains. This also automates and streamlines the application and infrastructure deployment.

Cisco VN-Link in combination with VMware Dynamic Resource Scheduler (DRS), balances the workloads across a pool of resources with enhanced mobility and security. The throughput increased by up to 30 percent for reduced cost by using the Cisco VN-Link hardware-accelerated implementation that allows you to manage security and quality of service (QoS) on a per-virtual-machine basis. It can work as an effective for the companies
