A MMDB Cluster Based Cloud Platform for Query-Intensive Web Information Systems

In recent years, with the rapid development of Internet, those Query-Intensive web information systems can not meet the requirement of high performance, which mainly comes from the following two aspects. First, most database systems that web information systems use store the related data in disks, which causes the slow data access. Second, it is hard to support large numbers of users accessing in parallel due to the limitation of single server´s physical resources, which causes the server overload. For solving the problems, this paper proposes a MMDB (Main-Memory Database) cluster based cloud platform for Query-Intensive web information systems. First, we design a MMDB cluster based web information system according to the current technology. Second, we develop a model-based cloud platform, which provides support for the MMDB cluster based web information system at an architecture level. The experiment on a real-world cloud demonstrates the feasibility, effectiveness and benefits of the new approach to improving the performance of those Query-Intensive web information systems.
