Multi-access Edge Computing (MEC) relies on the combination of various cutting-edge technologies  such as cloud computing and virtualization, a concept deployed near the end user (UE) proximity, instead of a central location. Furthermore, utilizing network function virtualization (NFV), software defined networks (SDN) and network slicing (NS) attributes, crucial requirements such as flexibility and multitenancy support are enabled.
