11 11 Virtualization

12 12 Virtualization Virtualization is a proven software technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute. 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.

13 13 How Virtualization works? Virtualization lets you transform hardware into software. Use software such as VMware 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.

14 14 How Virtualization works? 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.

15 15 What is a Virtual Machine? 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). 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 or applications can’t tell the difference between a virtual machine and a physical machine. Even the virtual machine thinks it is a “real” computer. An operating system or applications can’t tell the difference between a virtual machine and a physical machine. 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.

16 16 VMware approach 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.

17 17 Benefits Virtualization (1) 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 let you host multiple operating systems and multiple applications locally and in remote locations, freeing you from physical and geographical limitations.

18 18 Benefits Virtualization (2) 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

19 19 Virtual Infrastructure 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. a virtual infrastructure is a dynamic mapping of physical resources to business needs.

20 20 Benefits of Virtual Infrastructure 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.
