Such as grid computing distributed computing parallel computing utility computing network storage virtualization and load balancing. To perform integrating multiple relative low-cost computing entities into one perfect system with powerful computing ability via the network and with the help of the SaaS PaaS IaaS MSP and other advanced business models distributing this powerful computing ability to the hands of the end user. Cloud computing system mainly uses MapReduce model. The core design idea of MapReduce is to divide and conquer the problem and calculate on data rather than push data to calculate which effectively avoids many communication costs generated during data transmission., International Journal of Scientific Research in Computer Science Engineering and Information Technology, 2018, CSEIT184305
