Research on the Application Cluster Architecture for the New Computing Environment

Abstract

Driven by the 'nuclear high base' project, the autonomous new key software and hardware technology has made great breakthroughs. After adaptation, testing and evaluation, there are already some basic software and hardware computing environments with high availability, but the performance and reliability are far from the traditional computing environments. In order to make the application system effective and reliable in the autonomic controllable computing environment, this paper studies the application cluster architecture in the autonomic controllable computing environment, and proposes a cluster architecture that can extend the application nodes on demand. It breaks through the key technical issues of session sharing, transaction processing, task execution and service distribution involved in the architecture, realizes the load balancing of user requests, improves the overall response speed of the application, and users can access the application as long as any application service is not down, thus improving the overall reliability of the application. After the cluster validation of the electronic conference system, the performance and reliability of the system are improved obviously, and the application service nodes can be extended freely according to the number of users and handling capacity.
