Virtualization is the process of creating a software-based (or virtual) representation of something rather than a physical one. Virtualization can apply to applications, servers, storage, and networks and is the single most effective way to reduce IT expenses while boosting efficiency and agility for all size businesses. Virtualization slashes IT costs by making more efficient use of computing resources – improving the performance of hardware, software, operating systems, applications and, ultimately, your entire IT infrastructure. Where once you had to have very costly hardware for separating messaging, databases, file sharing, printing, and other network services, with Virtualization, you can leverage more capital by reducing the physical hardware requirements.
Servers, storage and desktops can be virtualized to simplify IT operations, reduce costs and improve performance. You can eliminate the traditional “one server, one application” IT approach and optimize your computing environment. Our team of technologists has the physical-to-virtual experience and tools required to develop an optimal computing environment to meet your unique needs and make the most out of your IT environment.
Reduce number of servers
Partitioning and isolation, the characteristics of server virtualization, enable simple and safe server consolidation.
Through consolidating, the number of physical servers can be greatly reduced. This alone brings benefits such as reduced floor space, power consumption and air conditioning costs. However, it is essential to note that even though the number of physical servers is greatly reduced, the number of virtual servers to be managed does not change. Therefore, when virtualizing servers, installation of operation management tools for efficient server management is recommended.
Server consolidation with virtualization reduces costs of hardware, maintenance, power, and air conditioning. In addition, it lowers the Total Cost of Ownership (TCO) by increasing the efficiency of server resources and operational changes, as well as virtualization-specific features. As a result of today’s improved server CPU performance, a few servers have high resource-usage rates but most are often underutilized. Virtualization can eliminate such ineffective use of CPU resources, plus optimize resources throughout the server environment. Furthermore, because servers managed by each business division’s staff can be centrally managed by a single administrator, operation management costs can be greatly reduced.
Improve availability and business continuity
One beneficial feature of virtualized servers not available in physical server environments is live migration. With live migration, virtual servers can be migrated to another physical server for tasks such as performing maintenance on the physical servers without shutting them down. Thus there is no impact on the end user. Another great advantage of virtualization technology is that its encapsulation and hardware-independence features enhance availability and business continuity.
Increase efficiency for development and test environments
At system development sites, servers are often used inefficiently. When different physical servers are used by each business division’s development team, the number of servers can easily increase. Conversely, when physical servers are shared by teams, reconfiguring development and test environments can be time and labor consuming.
Such issues can be resolved by using server virtualization to simultaneously run various operating system environments on one physical server, thereby enabling concurrent development and test of multiple environments. In addition, because development and test environments can be encapsulated and saved, reconfiguration is extremely simple.
