This article discusses the Mobile Edge Computing (MEC) architecture. A broad overview of ready-made platforms for IoT systems is presented. Examples of real use of ready-made systems in various fields are considered. The problem of delays in data processing is identified. Nowadays reduction in delays require large computing resources. A solution is proposed based on the modification of the MEC architecture using fog computing environments and cloud computing. An approach for transferring computations to the cloud and fog has been developed. The proposed approach was tested and the results were obtained in relation to the processing of a large amount of data (video information). Specific examples are given.
