The Computing Landscape of the 21st Century


The 4 tiers of future computing

At the recent International Workshop on Mobile Computing Systems and Applications (HotMobile 2019), held in Santa Cruz, California in February, Carnegie-Mellon Prof. Mahadev Satyanaryanan gave a keynote presentation on how future computing will be organized.

He emphasized that although computing technology is changing, the computing landscape is likely to be organized around 4 tiers, each with its own characteristic scale and power budget. The top tier comprises cloud computing in data centers, followed by a second tier of edge computers linked to the network. The third tier comprises small mobile devices, including the Internet of Things (IoT), powered by batteries. The final tier comprises networks of sensors, either passive or powered by energy harvesting.
