The disclosed technology is generally directed to communications in an IoT environment. In one example of the technology, a plurality of module twins that respectively correspond to a plurality of modules of edge applications on a plurality of edge devices are stored. The plurality of module twins individually include metadata associated with the corresponding module of the plurality of modules. A plurality of services is executed, such that the services of the plurality of services are configured to communicate with the modules of the plurality of modules. At least one service to be executed as a further module on at least one edge device of the plurality of edge devices is determined. The further module is caused to be deployed to the at least one edge device of the plurality of edge devices. Execution of the determined at least one service is ceased.
