Abstract: With the development of wireless communication technology and the Internet of things, the Internet of everything is becoming a reality and the number of connected devices is growing exponentially. Traditional cloud computing has powerful computation, storage, and network resources, but uncontrollable service delays will occur in the face of surges in data traffic. Edge computing places resources closer to the terminal, but the storage capacity of edge devices is small, and the processors equipped with them usually have weak computing power, so edge computing has low latency but limited resources. By combining the advantages of both cloud computing and edge computing, cloud-edge collaboration can effectively improve resource service capacity and service quality. It has a broad development prospect. Resource collaboration is an important aspect of cloud-edge collaborative service capabilities. Task offloading technology is one of the key technologies of cloud-edge resource collaboration. To promote the future development of this field and inspire researchers, the task offloading technology in cloud-edge resource collaboration is analyzed. Firstly, this paper sorts out the development history of cloud-edge collaboration and introduces the concept connotation of cloud-edge resource collaboration and task offloading, as well as the application scenarios of cloud-edge resource collaboration. Then, this paper summarizes the development of this technology at home and abroad from three aspects: uninstall objects, uninstall granularity, and service quality evaluation indicators. Finally, this paper proposes future development directions of task offloading technology in cloud-edge resource collaboration.

Key words: cloud-edge collaboration, resource collaboration, cloud computing, edge computing
