Server virtualization is the partitioning of a physical server into smaller virtual servers to help maximize your server resources. Without server virtualization, servers only use a small part of their processing power. Each virtual server can run its own applications and operating system. With small or midsized loads, you may be able to virtualize the database server and the Web server. Server virtualization can be viewed as a part of overall virtualization trend in the IT companies that include network virtualization, storage virtualization & management of workload. Reduced costs Server virtualization is a cost-effective way to provide web hosting services and effectively utilize existing resources in IT infrastructure. These are running on another operating system known as host operating system. This is in contrast to dedicating one server to a single application or task. This hypervisor sits over server hardware and regulates resources of each VM. Data centers become overcrowded with underutilized servers, causing a waste of resources and power. This technique is mainly used in web-servers which reduces the cost of web-hosting services. With a dynamic Web site, there are additional challenges for Web server virtualization: Database server performance is disk-bound, because there is a lot of disk I/O on a database server. Server virtualization attempts to address both of these issues in one fell swoop. ProArt So you can host more applications and data, more cost-effectively than ever. This division of one physical server into multiple isolated virtual servers is done by server administrator using software. By having each physical server divided into multiple virtual servers, server virtualization allows each virtual server to act as a unique physical device. It is the division of physical server into several virtual servers and this division is mainly done to improvise the utility of server resource. In other word it is the masking of resources that are located in server which includes the number & identity of processors, physical servers & the operating system. According to Market Research Future, the server virtualization market is expected to grow at approximately $8 billion by 2023, at 7% of CAGR between 2017 and 2023. Server virtualization can also be used in web servers as a low-cost way to host web services. Instead of having separate system for each web-server, multiple virtual servers can run on the same system/computer. By using specially designed software, an administrator can convert one physical server into multiple virtual machines. Server virtualization can also used to eliminate server sprawl (Server sprawl is a situation in which many under-utilized servers utilize more space or consume more resources than can be justified by their workload) & uses server resources efficiently. Before server virtualization became mainstream, each individual operating system required a physical platform, typically a server with CPU, Disk, Memory and other associated hardware to host the operating system.
