Abstract: The fast adoption and success of IoT and 5G related technology, accompanied by the ever-increasing critical demand for better QoS, revolutionized the paradigm shift from centralized cloud computing to some combination of distributed edge computing and traditional cloud computing. There are sub- stantial researches and reviews on edge computing, and several industry-specific frameworks were proposed, but general purpose frameworks that could enable speedy utilization of millions of innovated business/IT services worldwide across the entire spectrum of the current computing paradigm is not yet properly addressed. We first proposed a generalized and service-oriented edge computing framework, based on a relatively complete survey of recent publications, then we conducted an in-depth analysis of selected works from both academia and industry aimed to access the maturity, and the gaps in this arena. Finally, we summarize the challenges and opportunities in edge computing, and we hope that this paper can inspire significant future improvements.
