Benefits of Virtualization
Virtualization can increase IT agility, flexibility, and scalability while creating significant cost savings. Greater workload mobility, increased performance and availability of resources, automated operations — they’re all benefits of virtualization that make IT simpler to manage and less costly to own and operate.
- Reduced 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.
- Availability of a true Software-Defined Data Center.
Virtualization Explained
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.
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.
Virtual Machines Explained
A virtual computer system is known as a “virtual machine” (VM): a tightly isolated software container with an operating system and application inside. Each self-contained VM is completely independent. Putting multiple VMs on a single computer enables several operating systems and applications to run on just one physical server, or “host.”
A thin layer of software called a “hypervisor” decouples the virtual machines from the host and dynamically allocates computing resources to each virtual machine as needed.
Types of Virtualization
- Desktop Virtualization — Deliver virtual desktops to end users over a network.
- Server Virtualization — Run multiple virtual servers on a single physical machine.
- Network Virtualization — Combine hardware and software network resources into a single, software-based administrative entity.
