A virtualized IT Infrastructure: Simpler to manage, with an increased agility and flexibility.
Infrastructure virtualization makes the organization servers, workstations, storage and other systems, independent of the physical hardware layer, separating compute environments from the actual physical infrastructure. Thus server resources become virtual, including the number and identity of individual physical servers, processors, and operating systems. The Infrastructure administrator uses a software application to manage the resources, and divide physical servers into multiple isolated virtual environments.
Server virtualization can increase IT agility, flexibility, and scalability while creating significant cost savings. Workloads get deployed faster, performance and availability increase, and operations become automated, resulting in IT that's simpler to manage and less costly to own and operate.
- Isolation: Lets each virtual server run its own operating system, and each virtual server can be independently rebooted
- Optimization: Reduces costs because less hardware is required
- Efficiency: Conserves space through consolidation, as several machines can be consolidated into one server running multiple virtual environments
- Utilization: Utilizes resources to the fullest so it can also save on operational costs (e.g. using a lower number of physical servers reduces hardware maintenance)
- Flexibility: Services and applications are no longer locked to specific hardware resources, which now act as a dynamic pool that can even be over-provisioned if temporarily needed
- Availability: Virtual environments offer embedded high-availability features that help protect running services without the cost and complexity of service-level protection
- Simplicity: Although virtualization adds a layer to the infrastructure, this layer considerably simplifies management and deployments, and allows for quickly provisioning new services without the need to go through lengthy procurement cycles
