Why should IT outsourcing services be implemented The server Virtualization?
With the significant improvement of server hardware performance, server virtualization has become the first choice for the operation and maintenance of IT outsourcing service departments. Server virtualization is the application of system virtualization to servers. Multiple virtual servers are used according to the hardware performance of a physical server.
The core of server virtualization is to virtualize CPU, memory, hard disk and I/O devices and distribute them to each virtual server. So why should enterprises implement server virtualization in IT outsourcing services?
1) Reduce operating costs
Server virtualization reduces the operating costs of IT infrastructure. Server virtualization has greatly reduced the number of physical servers, freeing system administrators from the heavy management of physical servers, OS, middleware and compatibility, reducing the cost of computer room space and server procurement costs. The overall operation and maintenance cost is reduced.
2) Improve application compatibility
Server virtualization Since the CPU, RAM, and HD virtualized by the software are standardized, the generated virtual server has great standardization and good compatibility. Just build an application version and publish it to different types of standard platforms after virtualization.
3) More convenient application deployment
With server virtualization technology, deployment can be completed by inputting configuration parameters, copying virtual machines, calling templates, starting virtual machines, and activating virtual machines, which greatly shortens deployment time, eliminates manual intervention, and reduces deployment costs.
4) Improve service availability
Users can easily backup virtual machines and configure clusters. After dynamic migration of virtual machines, it is convenient to restore backups or run backups on other physical machines, greatly improving service availability.
5) Improve the utilization rate of equipment resources
Through the integration of server virtualization, the utilization rate of CPU, memory, storage, network and other devices is improved, while the availability of the original services is guaranteed, which makes the devices get a great use.
6) Easy to manage on a large scale
In the server virtualization technology, the data center has changed from a traditional single server to a shared resource pool. Users can adjust the virtual machine resources in real time. At the same time, the data center manager and the data center administrator can flexibly allocate the resources adjusted to the virtual machine according to the use of the internal resources of the virtual machine, improving the management efficiency.
