Keynote: IoT in Edge and Fog Environments
Janick Edinger · 2021
Over the past decade, cloud computing has demonstrated its potential to provide powerful and reliable resources at the core of the network. Many applications can benefit from the wide range of centrally managed cloud services. However, as Internet of Things (IoT) applications proliferate, the requirements for distributed computing environments are changing. Timecritical applications that need to spontaneously transfer large amounts of data would suffer from centralized infrastructures. These developments have led to new concepts of distributed environments such as edge computing, where computational resources are located in close proximity. Applications can leverage powerful computing devices that offer lower latency, higher bandwidth, and higher levels of trust. Since many applications in the IoT collect large amounts of sensor data, often containing sensitive information, these applications benefit most from less centralized infrastructures at the edge of the network. However, edge computing reaches its limits when peak workloads require large amounts of reliable computing resources. Ultimately, fog computing combines the benefits of nearby edge resources on one side and high-performance, centralized cloud resources on the other [1]. In this talk, I will summarize the current discussion on edge and Fog architectures and discuss how they differ from established cloud computing infrastructures. I will present multiple use cases in the IoT domain and evaluate how these applications have contributed to the paradigm shift in distributed computing.
