Analyze the main functions of server virtualization Architecture Technology

Virtualization architecture, the most popular technology in the IT field in recent years, it has evolved from a simple PC virtual machine to a complete enterprise-level virtualization architecture from server virtualization to user interface virtualization, network virtualization, and storage virtualization. server virtualization is the core of the entire technology. The concept of server virtualization has different definitions in the industry, but its core is the same, that is, it is a method that can integrate multiple application services while, by prioritizing application services, server resources are allocated to the workloads that require them most to simplify management and improve efficiency. Its main functions include the following four aspects:

Integration Functions.A virtualized server is mainly composed of physical servers and virtualization programs. By dividing a physical server into multiple virtual machines, or virtualizing several scattered physical servers into a logical server, in this way, multiple operating systems and application services are integrated into a powerful virtualization architecture.

Dynamic migration.The dynamic migration mentioned here mainly refers to V2V (migration from virtual machines to virtual machines) technology. Specifically, when a server is shut down due to a fault, the virtual machines it hosts can be automatically switched to another virtual server, and the application service will not be interrupted throughout the process, enables online migration without system downtime.

Resource allocation function.Dynamic resource scheduling technology is introduced in the virtualization architecture technology. The system manages all virtual servers as a whole and automatically allocates dynamic resources as needed, maximize resource utilization while ensuring stable system operation.

Powerful management and control interface. You can monitor the running status of physical servers and virtual machines in real time through a visual interface to manage, maintain, and deploy all virtual resources.

Benefits of server virtualization

The benefits of using server virtualization technology are mainly manifested in the following aspects:

Reduced procurement costs.The integration of Application Servers through virtualization technology can greatly reduce enterprises' spending on procurement and save enterprises 34% ~ in hardware ~ 80% of procurement costs. At the same time, it can save software procurement costs. Software license cost is an important expense that enterprises cannot ignore. With the addition of software giants such as Microsoft and RedHat, the advantages of virtualization architecture technology in software costs have gradually been reflected.

Reduce system operation and maintenance costs.Virtualization integrates servers with better management tools, reducing the workload of management and maintenance personnel in terms of network, line, hardware and software maintenance, the information department has been freed from the traditional maintenance and management work and used more time and energy to promote innovation and business growth, which has also brought benefits to enterprises. Virtualization technology can reduce the number of physical servers, which means that the power consumption and heat dissipation of enterprise data centers are reduced, while saving enterprises the cost for transformation and upgrade of air conditioners and auxiliary equipment in data centers.

Improve resource utilization.Ensuring the rapid deployment of business systems is an important indicator of informatization. In traditional models, purchasing and installing servers takes a long period of time, which limits the system deployment efficiency to a certain extent. By using virtualization technology, you can quickly build a virtual system platform, greatly reducing deployment preparation time and improving work efficiency. Because the virtualization server has the dynamic resource allocation function, when the application load of a virtual machine is saturated, the system automatically allocates resources according to the previously defined allocation rules. According to the data indicators provided by most virtualization technology vendors, the average resource utilization can range from 5% ~ 15% to 60% ~ 80%.

Improve system security.Traditional server hardware maintenance usually requires several days of preparation and several hours of maintenance periods. In the virtualization architecture technology environment, server migration takes only a few seconds. Because the service is not interrupted during the migration process, the Administrator does not need to apply for system downtime. This reduces the management and maintenance workload and improves the system operation continuity. Currently, mainstream virtualization technology vendors have introduced security mechanisms such as data snapshots and virtual storage in their virtualization platforms. Therefore, in terms of data security levels and system Disaster Tolerance capabilities, compared with the original standalone running mode.

To sum up, the virtualization Architecture Technology Integration Server can provide a broader development space for the rapid development of information technology in the industry, this has brought significant effects to enterprises in terms of reducing procurement costs, saving operation and maintenance costs, improving usage efficiency, and enhancing system security. However, the realization of the virtual server architecture is not the end of the industry's IT architecture change, but a new starting point. We firmly believe that in the near future, green, energy-saving, efficient, and secure virtualization architecture technologies will provide a more solid guarantee for promoting the informatization of the industry.
