The Design And Implementation Of A High-Availability System Platform For Uninterrupted Service

With the rapid development of server technology and the continuous expansion of its applications, the reliability and stability of the server systems also face more severe challenges. The critical services provided by application servers must be24hours online and keep providing uninterrupted online services. For example, in the sectors such as government agencies, financial industry, mobile Internet, energy transportation, the server system, as a core device, must handle a large number of critical information and services. Once the server is down, it would bring inestimable loss. Therefore, the high availability system platform will play an important role in the applications of uninterrupted service and core data protection. The uninterrupted service-oriented system platform is designed exactly to provide a complete protection system for online services and disaster recovery. A complete high-availability system platform can automatically migrate and take over the application services and database services, so as to keep the continuity of information online services.Through analysis and research, this thesis proposes the design of the high-availability system platform for uninterrupted services, and solves the key problems in the implementation of the core software based on the investigation and study of the current high-availability system research and development status. After that, the high-availability system platform for uninterrupted services is implemented. The main work completed by this thesis is as follows:1. Study and analyze the current status of the high-availability system, and give the architecture design of the high-availability system platform for uninterrupted services.2. Based on the mainstream cluster technologies and application software design strategies, give the implementation schemes for the uninterrupted service-oriented high-availability system platform and the specific implementation for the core business process.3. Aim at the requirements of the uninterrupted service applications, the test and comparative analysis are performed for the implemented high-availability system platform, and finally a practical application case is also given.The high-availability system platform studied and implemented in this thesis can be used by the users who have key businesses running on the servers, and achieve uninterrupted services and disaster recovery protection for the online systems.
