Internet of Things, Edge computing, Cloud computing, and Multi-edge computing are booming in the education and business. MEC, or mobile edge computing, is a critical technology that can maximize mobile resources by hosting compute-intensive applications, processing massive data before transferring it to the cloud, and providing user with cloud computing capabilities. A straightforward and concise overview of these computing paradigms and their relationships and each paradigm like cloud computing evolution from edge computing is addressed with its key points and relationships. This survey provides a holistic description of MEC technology and its possible applications along with different computing paradigms.
