Abstract: With the commercialization of 5G network,and the development of IoT and AI, the scale and complexity of edge computing have increased significantly. New services such as edge real-time computing, edge real-time analysis and edge intelligence are emerging, which require higher efficiency, reliability and resource utilization of edge infrastructure. How to adapt to the development trend of cloud computing and build Mobile Edge Computing (MEC)
infrastructure has become a new topic. This paper reviews the development status of MEC, including the scale of MEC industry and the pilot work results of international and domestic telecom operators in MEC, and discusses the impact of the multi-cloud and hybrid cloud on MEC. Afterwards, the issues and challenges of MEC are analyzed and some suggestions based on the telecom operators’ practices are proposed.

Key words: Mobile Edge Computing, cloud computing, hybrid cloud, edge infrastructure
