Research and Application on Distributed Multi-Level Cache Architecture

With the rapid development of Internet technology, caching technology has become a key technology of various large and medium-sized websites. The quality of cache design is directly related to the speed of website access and the number of servers purchased., and even affects the user experience. With the increase of user access and concurrency, the design of traditional small Internet architecture can not meet the needs of business., and cache technology is particularly important. How to design a cache architecture that can resist high concurrency and large amount of data is a problem worthy of in-depth research. This paper first introduces the commonly used cache technology, then puts forward a scheme of multi-layer cache architecture, analyzes the problems existing in high concurrency., and puts forward the corresponding countermeasures. The cache architecture is further optimized. Finally., the cache architecture is applied to the actual scene of the palm life shopping mall module of the bank app, design the whole architecture and describe the related technology., and then the group experiment is carried out., the pressure test is verified. According to the experimental results., the cache architecture has the characteristics of high availability, anti high concurrency and ensuring data accuracy and stability.
