Cloud computing uses very large scalable and virtualized resources to provide services based on different requirement via computer network in any time and at any place. As a crucial factor affecting cloud services, task scheduling was researched by many experts and scholars. In this paper, the author studied some new characteristics of the task scheduling algorithm in cloud computing, and how to reduce use cost and the energy consumption of data centers, realize objectives such as maximization between efficiency and fairness and security.
