Improve your ROI with Virtualization
Virtualization essentially lets one computer do the job of multiple computers, by sharing the resources of a single computer across multiple environments. Virtual servers and virtual desktops lets you host multiple operating systems and multiple applications locally and in remote locations, freeing you from physical and geographical limitations. In addition to energy savings and lower capital expenses due to more efficient use of your hardware resources, you get high availability of resources, better desktop management, increased security, and improved disaster recovery processes when you build a virtual infrastructure.
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 originally designed to run only a single operating system and a single application, but virtualization breaks that bond, making it possible to run multiple operating systems and multiple applications on the same computer at the same time, increasing the utilization and flexibility of hardware.
Virtualization is a technology that can benefit anyone who uses a computer, from IT professionals and Mac enthusiasts to commercial businesses and government organizations. Join the millions of people around the world who use virtualization to save time, money and energy while achieving more with the computer hardware they already own.
How Does Virtualization Work?
In essence, virtualization lets you transform hardware into software. Use software such as VMware ESX Server 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.
Multiple virtual machines share hardware resources without interfering with each other so that you can safely run several operating systems and applications at the same time on a single computer.
The VMware Approach to Virtualization
The VMware approach to virtualization inserts a thin layer of software directly on the computer hardware or on a host operating system. This software layer creates virtual machines and contains a virtual machine monitor or “hypervisor” that allocates hardware resources dynamically and transparently so that multiple operating systems can run concurrently on a single physical computer without even knowing it.
However, virtualizing a single physical computer is just the beginning. VMware offers a robust virtualization platform that can scale across hundreds of interconnected physical computers and storage devices to form an entire virtual infrastructure.
The introduction of virtualization technology presents a number of opportunities for driving capital and operational efficiency above and beyond the simple benefit of safe partitioning. VMware's customers have harnessed the power of virtualization to better manage IT capacity, to provide better service levels, and to streamline IT processes. We have coined a term for virtualizing the IT infrastructure–we call it the virtual infrastructure.
What is a Virtual Infrastructure?
In essence, a virtual infrastructure is a dynamic mapping of physical resources to business needs. While a virtual machine represents the physical resources of a single computer, a virtual infrastructure represents the physical resources of the entire IT environment, aggregating x86 computers and their attached network and storage into a unified pool of IT resources.
Structurally, a virtual infrastructure consists of the following components:
Single-node hypervisors to enable full virtualization of each x86 computer.
A set of virtualization-based distributed system infrastructure services such as resource management to optimize available resources among virtual machines.
Automation solutions that provide special capabilities to optimize a particular IT process such as provisioning or disaster recovery.
By decoupling the entire software environment from its underlying hardware infrastructure, virtualization enables the aggregation of multiple servers, storage infrastructure and networks into shared pools of resources that can be delivered dynamically, securely and reliably to applications as needed. This pioneering approach enables organizations to build a computing infrastructure with high levels of utilization, availability, automation and flexibility using building blocks of inexpensive industry-standard servers.
Virtual Infrastructure Benefits
VMware has made it possible to fully realize the enormous benefits of virtualization in production-scale IT environments by building virtual infrastructure automation and management capabilities around a best-in-class hypervisor. In fact, 86% of VMware customers use virtualization in production and 43% deploy most new production applications in virtual machines.
VMware virtual infrastructure solutions are ideal for production environments in part because they run on industry-standard servers and desktops and support a wide range of operating system and application environments, as well as networking and storage infrastructure. We have designed our solutions to function independently of the hardware and operating system to provide customers with a broad platform choice. As a result, our solutions provide a key integration point for hardware and infrastructure management vendors to deliver differentiated value that can be applied uniformly across all application and operating system environments.
VMware customers who have adopted our virtual infrastructure solutions have reported dramatic results, including:
60-80% utilization rates for x86 servers (up from 5-15% in non-virtualized PCs)
Cost savings of more than $3,000 annually for every workload virtualized
Ability to provision new applications in minutes instead of days or weeks
85% improvement in recovery time from unplanned downtime
