FA2ST: Fog as a Service Technology

Fog computing has emerged as a promising solution for the Internet of Things (IoT) and next generation mobile networks. As an extension to cloud computing, it enables service provisioning along the continuum from the cloud to things for reducing latency and bandwidth demands, and for empowering end users in their vicinity. Specifically, fog computing can pool resources anywhere along this continuum and can deploy its service anywhere in this range, including in the cloud, at the edge or on the things. This new computing model will change the way we deliver services to customers and inspire new business models. It liberates the market from only the large organizations who can afford to build and operate powerful servers and huge data centers to also allow small companies and even an individual person to deploy and operate computing, storage, and control services at different scales in an IoT environment. To achieve the full potential of fog computing, we must address challenges from service providers' perspectives. We propose Fog As A Service Technology (FA2ST) and its architecture - a multi-level fog computing system for end-to-end service enablement in IoT.
