Design and performance analysis of web caching with integrated file system on FPGA

In the cloud computing era, internet resources are becoming ample and abundant; hence the rising gap between remote application users and the virtualization resources. Considerable efforts have been invested in distributed file system and web caching with different optimizing strategies to shrink and ultimately eliminate the gap, but few existing studies have combined the two together to enhance the performance of the web server systems. In this paper, we make a solid effort to reveal the feasibility of the integration. After challenging ourselves with significant difficulties in design, we manage to prototype an evaluation system which could bring higher throughput, lower response delay as well as integrated functionalities of file system, web caching mechanism and web services. Our experience in exploring the method of web accelerations will be taken as useful reference for researchers working on high performance web services and FPGA applications.
