  Multi-access edge computing (MEC) is an emerging paradigm that pushes
resources for sensing, communications, computing, storage and intelligence
(SCCSI) to the premises closer to the end users, i.e., the edge, so that they
could leverage the nearby rich resources to improve their quality of experience
(QoE). Due to the growing emerging applications targeting at intelligentizing
life-sustaining cyber-physical systems, this paradigm has become a hot research
topic, particularly when MEC is utilized to provide edge intelligence and
real-time processing and control. This article is to elaborate the research
issues along this line, including basic concepts and performance metrics,
killer applications, architectural design, modeling approaches and solutions,
and future research directions. It is hoped that this article provides a quick
introduction to this fruitful research area particularly for beginning
researchers.
