The main features of the Analysis Server virtualization Architecture Technology

In recent years it has been the most popular technology---virtualization architecture technology, which has been developed from the initial simple PC virtual machine to the server virtualization to user interface virtualization, network virtualization and storage virtualization of a set of enterprise-level virtualization architecture, and server virtualization is the core of the entire technology. With regard to the concept of server virtualization, the industry has a different definition, but its core is consistent, that is, it is a way to streamline management and improve efficiency by assigning server resources to the workloads that are most needed by differentiating application services, while consolidating multiple application services. Its main functions include the following four aspects:

Integrated integration capabilities. Virtualized servers are primarily composed of physical servers and virtualization programs that integrate multiple operating systems and application services into a powerful virtualization architecture by dividing one physical server into multiple virtual machines or by virtual a number of decentralized physical servers into a single logical server.

Dynamic migration function. The dynamic migration mentioned here refers to the technology of WebPart (the migration of virtual machine to virtual machine). Specifically, when a server due to downtime, its hosted virtual machine can automatically switch to another virtual server, while the entire process of application services will not be interrupted, the system 0 downtime online migration.

Resource allocation function. In the virtualization architecture technology, dynamic resource scheduling technology is introduced, all virtual servers are managed as a whole resource, and dynamic resources are allocated automatically according to the actual demand, and the resource utilization is maximized under the premise of guaranteeing the stable operation of the system.

Powerful management control interface. Through the visual interface real-time monitoring physical server and the operation of each virtual machine, to achieve all the virtual resources management, maintenance and deployment operations.

Benefits of Server Virtualization

The benefits of using server virtualization technology are mainly shown in the following aspects.

Save on purchasing cost. Through the virtualization technology to the application server integration, can greatly reduce the enterprise in the purchase link expenditure, in the hardware link can save the 34%~80% purchase cost for the enterprise. At the same time, can also save software procurement costs. Software licensing cost is an important expense that enterprises can not ignore. With the addition of Microsoft, Red Hat and other software giants, the advantage of virtualization architecture technology in software cost is gradually embodied.

Reduce system operation and maintenance costs. As virtualization integrates servers with better management tools, reduces the workload of management maintainers in the areas of networking, wiring, and hardware and software maintenance, freeing the information sector from traditional maintenance management efforts, and more time and effort to drive innovation and business growth, This also brings benefits to the enterprise. Through virtualization technology can reduce the number of physical servers, which means that the enterprise room power consumption, the reduction of heat dissipation, but also for the enterprise to save air-conditioning, computer room equipment upgrades upgrade costs.

Increase resource utilization. To ensure the rapid deployment of business system is an important index of information work, while the traditional mode of server procurement and installation cycle is long, to some extent, limited the efficiency of the system deployment. Using virtualization technology, we can quickly build virtual system platform, greatly reduce the deployment lead time and improve work efficiency. Because virtualized servers have dynamic resource allocation capabilities, when the application load of a virtual machine becomes saturated, provisioning is automated based on previously defined allocation rules. According to the data metrics provided by most of the virtualization technology vendors, the average utilization of resources can be increased from 5%~15% to 60%~80% after virtualization consolidates the servers.

Improve the security of the system. Traditional server hardware maintenance usually takes several days of preparation and hours of maintenance window periods. In the Virtualization Architecture technology environment, server migration takes only a few seconds. As the service is not interrupted during the migration process, administrators need not apply for system downtime and improve the continuity of system operation while reducing the workload of management maintenance. At present, the virtualization mainstream technology vendors in their virtualization platform to introduce data snapshots and virtual storage and other security mechanisms, so in the data security level and system capacity for disaster tolerance, compared to the original stand-alone operating mode has been greatly improved.

To sum up, virtualization Architecture Technology Integration Server for the rapid development of industry information construction to provide a broader development space for the enterprise in reducing procurement costs, save operation and maintenance costs, improve the use of efficiency, enhance the security of the system to bring obvious results. But the implementation of the virtual server architecture is not the end of the industry it architecture change, but a new starting point. We firmly believe that in the near future, the green, energy-saving, efficient and safe virtualization architecture technology will provide a more solid guarantee for the construction of information industry.
