Server virtualization enables multiple operating systems to run on a single physical server as highly efficient virtual machines. Key benefits include:
Greater IT efficiencies
Reduced operating costs
Faster workload deployment
Increased application performance
Higher server availability
Eliminated server sprawl and complexity
Deploying desktops as a managed service enables IT organizations to respond faster to changing workplace needs and emerging opportunities. Virtualized desktops and applications can also be quickly and easily delivered to branch offices, outsourced and offshore employees, and mobile workers using iPad and Android tablets.
By completely reproducing a physical network, network virtualization allows applications to run on a virtual network as if they were running on a physical network — but with greater operational benefits and all the hardware independencies of virtualization. (Network virtualization presents logical networking devices and services — logical ports, switches, routers, firewalls, load balancers, VPNs and more — to connected workloads.)
Virtualization vs. Cloud Computing
Although equally buzz-worthy technologies, virtualization and cloud computing are not interchangeable. Virtualization is software that makes computing environments independent of physical infrastructure, while cloud computing is a service that delivers shared computing resources (software and/or data) on demand via the Internet. As complementary solutions, organizations can begin by virtualizing their servers and then moving to cloud computing for even greater agility and self-service.
