Computing as a service pattern based on edge computing

Abstract

Edge computing is a computational model for all terminal devices from cloud to edge path, which emerges in the era of interconnection of all things. The existing server pattern under cloud computing model cannot satisfy the application requirements of edge computing model. It mainly embodies in the limitation of edge device resources, the real-time nature of edge device services and the intelligence of edge device decision-making. Aiming at the characteristics of application requirements of edge computing model, this paper proposes a service pattern suitable for edge computing model—computing as a server pattern(CaaS)，and abstracts the task model, computing model and service model provided by this pattern.
