Virtualization Technology
What is Virtualization?
Virtualization is a proven software technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute. Until recently, the most 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 across numerous environments. Different virtual machines can run different operating systems and many diverse applications on the same physical computer.
How Does Virtualization Work?
Software such as VMware's vSphere/ESXi and Microsoft's Hyper-V, 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.
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 at any time.
Flexible Architecture
Virtualizing a single physical computer is just the beginning. Virtualization can be performed across hundreds of interconnected physical computers and storage devices to form an entire virtual infrastructure. 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. This “internal cloud” means your highest priority applications will always have the resources they need without wasting money on excess hardware only needed for peak times. The internal cloud can connect to an external cloud as well, giving your business the flexibility, availability and scalability it needs to thrive.
Lower TCO
Virtualization allows for an increase in availability of core services while eliminating error-prone manual tasks. IT operations are more efficient and cost effective in virtualized environment because we can do more with less physical hardware. Through the use of virtualization technology, Infracore can deliver built-in availability, security, and performance across the board, from the desktop to the datacenter.
