A Fog-Based Technique For Optimized Distributed Cloud Cache

Cloud data centers can face many challenges at certain times due to the huge number of requests to access and download specific data sets or files for software, games, movies, and several other types of data as they are released. Here we propose the use of distributed cloud cache, to help solve this problem. This distributed cloud cache uses small cache nodes and dual direction parallel transfer techniques to reduce the overload on the cloud data centers. This involves creating multiple small cache nodes that will help a data center partition the requested data set or file across these nodes and the data center itself. These small cache nodes can be distributed over multiple locations on the Internet to balance the ongoing download rates and to reduce the overhead on the cloud data center. The distributed cache nodes can be mounted over some dedicated servers or on fog platforms. We implemented and evaluated the proposed distributed cloud cache, and the results show considerable performance gains.
