Virtualization is technology that lets you create useful IT services using resources that are traditionally bound to hardware. It allows you to use a physical machine’s full capacity by distributing its capabilities among many users or environments.
Virtualization is the process of creating a software-based, or virtual, representation of something, such as virtual applications, servers, storage and networks. It is the single most effective way to reduce IT expenses while boosting efficiency and agility for all size businesses. Devices, applications and human users are able to interact with the virtual resource as if it were a real single logical resource.
In other words, Virtualization is a technique, which allows to share a single physical instance of a resource or an application among multiple customers and organizations. It does by assigning a logical name to a physical storage and providing a pointer to that physical resource when demanded.
Due to the limitations of x86 servers, many IT organizations must deploy multiple servers, each operating at a fraction of their capacity, to keep pace with today’s high storage and processing demands. The result: huge inefficiencies and excessive operating costs.
Enter virtualization. Virtualization relies on software to simulate hardware functionality and create a virtual computer system. This enables IT organizations to run more than one virtual system – and multiple operating systems and applications – on a single server. The resulting benefits include economies of scale and greater efficiency.
Virtualization increases IT agility, flexibility and scalability while creating significant cost savings. Greater workload mobility, increased performance and availability of resources, automated operations – all these benefits of virtualization makes IT simpler to manage and less costly to own and operate. Other benefits include the reduction of capital and operating costs, minimized or eliminated downtime, increased IT productivity, efficiency, agility and responsiveness, faster provisioning of applications and resources, greater business continuity and disaster recovery, simplified data center management, and availability of a true Software-Defined Data Center.
