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. This technology is production-proven, used by more than 150,000 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 and VMware 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.

On-Demand, Pay-As-You-Go Infrastructure as a Service

vCloud Express is an Infrastructure as a Service (IaaS) offering delivered by leading VMware service provider partners. It provides reliable, on-demand, pay-as-you-go infrastructure that ensures compatibility with internal VMware environments and with VMware Virtualized™ services.

This class of service allows IT to reduce both the capex and resource challenges associated with the fluctuating infrastructure requirements of development teams. Developers are able to use the vCloud Express service at their convenience to address various infrastructure and programming needs such as experimentation, prototyping and testing. The vCloud Express service retains the robustness, interoperability and reliability that VMware is known for.

Our vCloud Partner Ecosystem, which includes the ISV and open source community has taken note of our investment in vCloud and is integrating key solutions with the VMware vCloud API as part of innovative services from VMware vCloud Express providers. For example, we now have available both Java and Python software development kits (SDKs) for the vCloud API, making it easier for developers and ISVs to jumpstart their projects by flexibly leveraging private and public cloud services via the vCloud API.
