Approaches for multi-tier cloud structure management

The number of IoT devices is constantly increasing every year. The volume of generated traffic is also increasing. Therefore, the new generation of 5G networks uses technology to reduce load and reverse delays-MEC. The MEC architecture is based on a multi-tier cloud structure, but official international documents do not define the principle at which architecture level a cloud computing is selected to manage the processing of user data. Therefore, in this article, we propose comparing three architectures for managing the choice of a cloud computing. It is proposed to implement a multi-tier cloud structure on the OpenStack platform. © 2019 IEEE
