Strategies for Data and Computation Movements in Fog Computing

Fog computing is a continuum of resources between the cloud provider and the edge of the network. Such resources can be used to host data and computation that can be moved from the cloud provider to near the consumer in order to increase the quality of the services provided. This tutorial presents a method to select the best data or computation movement to be enacted. The tutorial is divided in three sessions. The first session introduces the fog computing architecture. The second session introduces data and computation movement: their challenges and the available technologies used to enact them. The third session presents the actual method. In particular, how the method uses a goal-based modelling language to define the requirements of consumers, the impact of data and computation movements on their requirements and how it permits to choose the best movement.
