What is Virtualization?

Today’s x86 computer hardware was designed to run a single operating system and a single application, leaving most machines vastly underutilized. Virtualization lets you run multiple virtual machines on a single physical machine, with each virtual machine sharing the resources of that one physical 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 vSphereto 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 machinethat 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 with VMware vSphere, a proven virtualization platform used 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.

Why Your Company Should Virtualize

Virtualizing your IT infrastructure lets you reduce IT costs while increasing the efficiency, utilization, and flexibility of your existing assets. Around the world, companies of every size benefit from VMware virtualization. Thousands of organizations—including all of the Fortune 100—use VMware virtualization solutions. See how virtualizing 100% of your IT infrastructure will benefit your organization.

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.
  1. 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.
  1. Increase availability of hardware and applicationsfor improved business continuity: Securely backup and migrate entire virtual environments with no interruption in service. Eliminate planned downtime and recover immediately from unplanned issues.
  1. Gain operational flexibility: Respond to market changes with dynamic resource management, faster server provisioning and improved desktop and application deployment.
  1. Improve desktop manageability and security: Deploy, manage and monitor secure desktop environmentsthat users can access locally or remotely, with or without a network connection, on almost any standard desktop, laptop or tablet PC.
  2. What is a Virtual Machine?
  3. A virtual machine is a tightly isolated software container that can run its own operating systems and applications as if it were a physical computer. A virtual machine behaves exactly like a physical computer and contains it own virtual (ie, software-based) CPU, RAM hard disk and network interface card (NIC).
    An operating system can’t tell the difference between a virtual machine and a physical machine, nor can applications or other computers on a network. Even the virtual machine thinks it is a “real” computer. Nevertheless, a virtual machine is composed entirely of software and contains no hardware components whatsoever. As a result, virtual machines offer a number of distinct advantages over physical hardware
Virtual Machines Benefits

In general, VMware virtual machines possess four key characteristics that benefit the user:

  • Compatibility: Virtual machines are compatible with all standard x86 computers
  • Isolation: Virtual machines are isolated from each other as if physically separated
  • Encapsulation: Virtual machines encapsulate a complete computing environment
  • Hardware independence: Virtual machines run independently of underlying hardware

Compatibility

Just like a physical computer, a virtual machine hosts its own guest operating system and applications, and has all the components found in a physical computer (motherboard, VGA card, network card controller, etc). As a result, virtual machines are completely compatible with all standard x86 operating systems, applications and device drivers, so you can use a virtual machine to run all the same software that you would run on a physical x86 computer.

Isolation

While virtual machines can share the physical resources of a single computer, they remain completely isolated from each other as if they were separate physical machines. If, for example, there are four virtual machines on a single physical server and one of the virtual machines crashes, the other three virtual machines remain available. Isolation is an important reason why the availability and security of applications running in a virtual environment is far superior to applications running in a traditional, non-virtualized system.

Encapsulation

A virtual machine is essentially a software container that bundles or “encapsulates” a complete set of virtual hardware resources, as well as an operating system and all its applications, inside a software package. Encapsulation makes virtual machines incredibly portable and easy to manage. For example, you can move and copy a virtual machine from one location to another just like any other software file, or save a virtual machine on any standard data storage medium, from a pocket-sized USB flash memory card to an enterprise storage area networks (SANs).

Hardware Independence

Virtual machines are completely independent from their underlying physical hardware. For example, you can configure a virtual machine with virtual components (eg, CPU, network card, SCSI controller) that are completely different from the physical components that are present on the underlying hardware. Virtual machines on the same physical server can even run different kinds of operating systems (Windows, Linux, etc).
When coupled with the properties of encapsulation and compatibility, hardware independence gives you the freedom to move a virtual machine from one type of x86 computer to another without making any changes to the device drivers, operating system, or applications. Hardware independence also means that you can run a heterogeneous mixture of operating systems and applications on a single physical computer.

Use Virtual Machines as the Building Blocks of your Virtual Infrastructure

Virtual machines are a fundamental building block of a much larger solution: the virtual infrastructure. While a virtual machine represents the hardware resources of an entire computer, a virtual infrastructure represents the interconnected hardware resources of an entire IT infrastructure—including computers, network devices and shared storage resources. Organizations of all sizes use VMware solutions to build virtual server and desktop infrastructures that improve the availability, security and manageability of mission-critical applications.

Reduce Costs with a Virtual Infrastructure

Lower your capital and operational costs and improve operational efficiency and flexibility. Go beyond server consolidation and deploy a standard virtualization platform to automate your entire IT infrastructure. VMware customers have harnessed the power of virtualization to better manage IT capacity, provide better service levels, and streamline IT processes. We coined a term for virtualizing the IT infrastructure–we call it the virtual infrastructure.

What is a Virtual Infrastructure?

A virtual infrastructure lets you share your physical resources of multiple machines across your entire infrastructure. A virtual machinelets you share the resources of a single physical computer across multiple virtual machines for maximum efficiency. Resources are shared across multiple virtual machines and applications. Your business needs are the driving force behind dynamically mapping the physical resources of your infrastructure to applications—even as those needs evolve and change. Aggregate your x86 servers along with network and storage into a unified pool of IT resources that can be utilized by the applications when and where they’re needed. This resource optimization drives greater flexibility in the organization and results in lower capital and operational costs.

A virtual infrastructure consists of the following components:

  • Bare-metal hypervisorsto enable full virtualization of each x86 computer.
  • Virtual infrastructure services such as resource managementand consolidated backupto optimize available resources among virtual machines
  • Automation solutions that provide special capabilities to optimize a particular IT process such as provisioning or disaster recovery.

Decouple your software environment from its underlying hardware infrastructure so you can aggregate multiple servers, storage infrastructure and networks into shared pools of resources. Then dynamically deliver those resources, securely and reliably, to applications as needed. This pioneering approach lets our customers use building blocks of inexpensive industry-standard servers to build a self-optimizing datacenter and deliver high levels of utilization, availability, automation and flexibility.

History of Virtualization

Virtualization was first developed in the 1960s to partition large, mainframe hardware for better hardware utilization. Today, computers based on x86 architecture are faced with the same problems of rigidity and underutilization that mainframes faced in the 1960s. VMware invented virtualization for the x86 platform in the 1990s to address underutilization and other issues, overcoming many challenges in the process. Today, VMware is the global leader in x86 virtualization, with over 250,000customers, including 100% of the Fortune 100.

In the Beginning: Mainframe Virtualization

Virtualization was first implemented more than 30 years ago by IBM as a way to logically partition mainframe computers into separate virtual machines. These partitions allowed mainframes to “multitask”: run multiple applications and processes at the same time. Since mainframes were expensive resources at the time, they were designed for partitioning as a way to fully leverage the investment.

The Need for x86 Virtualization

Virtualization was effectively abandoned during the 1980s and 1990s when client-server applications and inexpensive x86 servers and desktops led to distributed computing. The broad adoption of Windows and the emergence of Linux as server operating systems in the 1990s established x86 servers as the industry standard. The growth in x86 server and desktop deployments led to new IT infrastructure and operational challenges. These challenges include:

  • Low Infrastructure Utilization. Typical x86 server deployments achieve an average utilization of only 10% to 15% of total capacity, according to International Data Corporation (IDC), a market research firm. Organizations typically run one application per server to avoid the risk of vulnerabilities in one application affecting the availability of another application on the same server.
  • Increasing Physical Infrastructure Costs. The operational costs to support growing physical infrastructure have steadily increased. Most computing infrastructure must remain operational at all times, resulting in power consumption, cooling and facilities costs that do not vary with utilization levels.
  • Increasing IT Management Costs. As computing environments become more complex, the level of specialized education and experience required for infrastructure management personnel and the associated costs of such personnel have increased. Organizations spend disproportionate time and resources on manual tasks associated with server maintenance, and thus require more personnel to complete these tasks.
  • Insufficient Failover and Disaster Protection. Organizations are increasingly affected by the downtime of critical server applications and inaccessibility of critical end user desktops. The threat of security attacks, natural disasters, health pandemics and terrorism has elevated the importance of business continuity planning for both desktops and servers.
  • High Maintenance end-user desktops. Managing and securing enterprise desktops present numerous challenges. Controlling a distributed desktop environment and enforcing management, access and security policies without impairing users’ ability to work effectively is complex and expensive. Numerous patches and upgrades must be continually applied to desktop environments to eliminate security vulnerabilities.

The VMware Solution: Full Virtualization of x86 Hardware

In 1999, VMware introduced virtualization to x86 systems to address many of these challenges and transform x86 systems into a general purpose, shared hardware infrastructure that offers full isolation, mobility and operating system choice for application environments.

Challenges & Obstacles to x86 Virtualization

Unlike mainframes, x86 machines were not designed to support full virtualization, and VMware had to overcome formidable challenges to create virtual machines out of x86 computers.
The basic function of most CPUs, both in mainframes and in PCs, is to execute a sequence of stored instructions (ie, a software program). In x86 processors, there are 17 specific instructions that create problems when virtualized, causing the operating system to display a warning, terminate the application, or simply crash altogether. As a result, these 17 instructions were a significant obstacle to the initial implementation of virtualization on x86 computers.
To handle the problematic instructions in the x86 architecture, VMware developed an adaptive virtualization technique that “traps” these instructions as they are generated and converts them into safe instructions that can be virtualized, while allowing all other instructions to be executed without intervention. The result is a high-performance virtual machinethat matches the host hardware and maintains total software compatibility. VMware pioneered this technique and is today the undisputed leader in virtualization technology.
