This paper aims to provide a clearer view of container technology, such as its advantages and disadvantages, how it can cooperate with Openstack, and document the improvements made by this cooperation. In terms of containerization technology, this paper will illustrate the components of Docker and the impact it has compared to the already classic technology of virtual machines. Another element to be addressed in this paper is the importance of moving some of the computing power to the periphery of networks. This can be done using existing peripheral devices to the extent that the computing resources on this equipment allow. This move is necessary to provide an infrastructure capable of supporting services with low latency needs, minimal delay (traffic sensor, vehicle sensors) and at the same time an infrastructure that will free the core of networks from a large volume of data. This paper will follow the comparison of household equipment that can play an active role in computing at the periphery of networks to highlight what types of applications or calculations can be performed on them.
