Benefits of Server Virtualization
Virtual servers have the well-known advantage of cutting hardware and service costs because a single physical machine can take the place of multiple systems without the expense associated with purchasing, provisioning, and housing extra equipment. But virtual server technology can also enhance the manageability and fault-tolerance of line-of-business servers, vastly reduce recovery time in case of a catastrophic failure, and improve overall network stability by isolating servers used for testing, development, or legacy applications.
The rapid pace of server hardware evolution makes it almost impossible for businesses to standardize on a specific computer brand and model. Equipment may be purchased from a single manufacturer over a 2-3 year timeframe, but individual models quickly become obsolete and unavailable for purchase. The result is often a hodgepodge of equipment that precludes the use of efficient server replication techniques such as template operating system installations. Consequently, most servers must be configured manually from scratch, which is time-consuming and expensive. Advanced configurations such as clustering or redundant servers are also more difficult to manage when servers lack interchangeable components.
A great advantage of server virtualization is that virtual host software such as Microsoft Hyper-V, VMware vSphere, and Citrix XenServer can create standardized environments from a patchwork of computer models and configurations. This dramatically simplifies server provisioning, deployment, and management. New servers can often be deployed in minutes instead of hours. The flexibility of moving virtual servers between physical servers makes it easy to realign server infrastructure to match varying application demands. As the need for application computing power increases, additional virtual host servers can be deployed rapidly, and existing virtual servers can be load balanced across the array of physical servers.
Benefits of Desktop Virtualization
Major improvements to VDI technology have been incorporated into virtual desktop platforms such as Microsoftís Remote Desktop Services, Web Apps, and Remote Desktop Connection for Mac as well as by XenApp from Citrix. Virtual desktops streamline desktop provisioning and administration, enforce security policies, reduce recovery time, and provide a powerful framework for collaboration. Progent offers expert support for designing, managing, and troubleshooting state-of-the-art desktop virtualization solutions from Microsoft and Citrix and for maintaining or upgrading legacy environments.
How Progent Can Help Businesses Benefit from Virtualization
Progent can help businesses design their network infrastructure to take full advantage of virtualization technology, help install and configure virtual servers and desktops to maximize performance, dependability, and manageability, propose and test business recovery plans that use virtualization to minimize downtown in case of a catastrophic failure, and provide support, troubleshooting, and consulting for virtual environments. Progent also offers a virtual server hosting service that allows small businesses to get the benefits of enterprise-class IT infrastructure and world-class support services at a fraction of the cost of creating and managing an in-house data center and an internal IT support group.
