One of the hottest concepts in the IT world, virtualization is a revolutionary software technology that is changing the way users all around the world compute. The powerful computers of today are designed to run a single operating system, leaving most of the hardware underutilized and unable to reach its full potential. Virtualization enables you to enjoy the full power of a computer by creating multiple virtual machines with a single physical machine. These virtual computers share the physical resources but can run their own operating systems and applications on the same piece of hardware. The virtualization market has exploded, evident in the plethora of VPS web hosting solutions and products specifically designed for the desktop environment. Thanks to this technology, you can now run a copy of Microsoft Windows on your Mac computer.
Virtualization Software in Action
Virtualization software products take hardware resources such as RAM, CPU and hard disk space to establish a fully functioning virtual machine that runs just like a single computer. Because these virtual machines have their own complete systems, potential conflicts with neighboring environments are virtually eliminated. Most virtualization programs works by applying a thin application layer on the host machine or operating system. This layer includes a VMM (virtual machine monitor) more commonly known as a hypervisor, which allocates hardware resources in a dynamic and transparent manner. After encapsulating the entire machine and its resources, a virtual computer is made completely compatible with all standard x86 operating systems and the applications that support them. Each machine has access to vital resources on an as needed basis.
Advanced Virtualization Technology
Virtualization technology has evolved so rapidly that some view the partitioning of a single computer as a thing of the past. Software developer Vmware, one of the virtualization pioneers, helped the technology climb to new heights with its vSphere product, the first cloud computing operating system to hit the market. vSphere is capable of scaling across numerous physical networked computers and storage devices to create a complete virtual IT infrastructure. This means there is no need to permanently allocate servers, storage and bandwidth to each individual application. Instead, these network resources are dynamically allocated when needed. vSphere offers an internal cloud that ensures your most critical applications will always be able to access the resources they need without shelling out extra money on hardware that is generally only needed during peak times. Because it can also be connected with an external cloud, vSphere can provide organizations with the flexibility, scalability and availability they need to flourish in today’s fast-paced IT world. These are just a few examples of how virtualization is quickly growing right before are very eyes.
Conclusion
Aside from the cloud, virtualization is perhaps the most talked about computing technology today. Ironically, these two concepts compliment each other well and make a perfect match when combined together. Virtualization allows your IT staff to efficiently handle multiple servers, providing users with access to the resources and services the need all while maintaining centralized authority. This technology has become the perfect way to deliver the security, performance and availability a thriving organization demands from the desktop to the data center environment.
