What is Virtualization?

Virtualization is a proven software technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute. Today’s powerful x86 computer hardware was designed to run a single operating system and a single application. This leaves most machines vastly underutilized. Virtualization lets you run multiple virtual machines on a single physical machine, sharing the resources of that single computer across multiple environments. Different virtual machines can run different operating systems and multiple applications on the same physical computer. While others are leaping aboard the virtualization bandwagon now, VMware is the market leader in virtualization. Our technology is production-proven, used by more than 170,000 customers, including 100% of the Fortune 100.

How Does Virtualization Work?

The VMware virtualization platform is built on a business-ready architecture. Use software such as VMware vSphere andVMware ESXi (a free download) to transform or “virtualize” the hardware resources of an x86-based computer—including the CPU, RAM, hard disk and network controller—to create a fully functional virtual machine that can run its own operating system and applications just like a “real” computer. Each virtual machine contains a complete system, eliminating potential conflicts. VMware virtualization works by inserting a thin layer of software directly on the computer hardware or on a host operating system. This contains a virtual machine monitor or “hypervisor” that allocates hardware resources dynamically and transparently. Multiple operating systems run concurrently on a single physical computer and share hardware resources with each other. By encapsulating an entire machine, including CPU, memory, operating system, and network devices, a virtual machine is completely compatible with all standard x86 operating systems, applications, and device drivers. You can safely run several operating systems and applications at the same time on a single computer, with each having access to the resources it needs when it needs them.

Build your Datacenter on a Flexible Architecture

Virtualizing a single physical computer is just the beginning. You can build an entire virtual infrastructure, scaling across hundreds of interconnected physical computers and storage devices withVMware vSphere, a proven virtualization platform uses as the foundation for building private and public clouds. You don’t need to assign servers, storage, or network bandwidth permanently to each application. Instead, your hardware resources are dynamically allocated when and where they’re needed within your private cloud. Your highest priority applications always have the necessary resources without wasting money on excess hardware only used at peak times. Connect this private cloud to a public cloud to create a hybrid cloud, giving your business the flexibility, availability and scalability it needs to thrive.

Manage your Resources with the Lowest TCO

It’s not just virtualization that’s important. You need the management tools to run those machines and the ability to run the wide selection of applications and infrastructure services your business depends on. VMware lets you increase service availability while eliminating error-prone manual tasks. IT operations are more efficient and effective with VMware virtualization. Your staff will handle double or triple the number of servers, giving users access to the services they need while retaining centralized control. Deliver built-in availability, security, and performance across the board, from the desktop to the datacenter.

Top 5 Reasons to Adopt Virtualization Software

  1. Get more out of your existing resources: Pool common infrastructure resources and break the legacy “one application to one server” model with server consolidation.
  2. Reduce datacenter costs by reducing your physical infrastructure and improving your server to admin ratio: Fewer servers and related IT hardware means reduced real estate and reduced power and cooling requirements. Better management tools let you improve your server to admin ratio so personnel requirements are reduced as well.
  3. Increase availability of hardware and applications for improved business continuity: Securely backup and migrate entire virtual environments with no interruption in service. Eliminate planned downtime and recover immediately from unplanned issues.
  4. Gain operational flexibility: Respond to market changes with dynamic resource management, faster server provisioning and improved desktop and application deployment.
  5. Improve desktop manageability and security: Deploy, manage and monitor secure desktop environments that users can access locally or remotely, with or without a network connection, on almost any standard desktop, laptop or tablet PC.
