Design And Implementation Of SNS Photo Sharing System Based On Cache Cluster

With the rapid development of the modern Internet, especially the vigorous development of the SNS (Social Network Service), the Internet technology has greatly enriched the human dynamics. Which also brings a situation that the users’ relationship network become more and more complex and the amount of users’ data rapidly accumulate. With the massive data and high concurrent requests, data cache and cluster technology has become a major way to enhance the response ability of WEB system.In the design of SNS photo sharing system, the performance problem caused by data access has become an urgent problem to solve. Although the database cluster technology can support the explosive growth volume of data, but as long as this technique is based on the relational database, it’s still unable to shake off the performance loss of SQL statement parsing and disk IO, which also means it’s cannot satisfy the high concurrent of requests. In order to improve the processing and response capability of the server, the data cache is one of the essential system component. This paper reference some internet companies now commonly used:cluster server +cache architecture, trying to solve the performance bottleneck caused by data access.The main work of this paper includes:designed and implemented a simple and easy use SNS photo sharing system, whose WEB server supporting cluster structure and cache; Combined the cluster technology and cache technology, this paper implemented a high performance, high reliability, extendible and application independent cache cluster system and its access middleware. After sufficient testing, the cache cluster system is used in the SNS photo sharing system.
