4.2.19 Cloud vs fog computing
Cloud computing solutions will create substantial increases in bandwidth needs as data and services are moved and processed in the Cloud, promoting organisational flexibility and agility.
However, some data and service solutions are more appropriate closer to the source. For example, smart light traffic systems require real-time processing. The selected computing model must enable the level of resiliency, scale, speed, and mobility that is required to efficiently use the data.
To deliver the best value, system designers must consider the distribution of data and account for different computing models. As a result, some services and applications may need to move from the cloud into the fog. This can help manage escalating bandwidth needs.
