**Edge Computing: Vision and Challenges** The paper introduces the concept of a new computing paradigm, _edge computing_ brought on by the proliferation of Internet of Things (IoT) devices. The authors list the need for fast and efficient processing of data closer to the source rather than the traditional cloud computing paradigm. The paper then goes on to showcase the potential benefits of edge computing, providing case studies and listing present challenges. The paper describes edge computing as the solution to bringing data processing to the end user, overcoming the limitations of, the more traditional, cloud computing. The idea laid out in the paper especially benefits scenarios involving IoT devices. Some of the benefits ascribed to cloud computing are enhanced response times, reducing bandwidth, and enhancing the security posture. These benefits are directly linked to the inadequacies of cloud computing in the field of real-time data processing specifically for applications involving autonomous vehicles, smart cities and smart homes (an example cited throughout the paper). The authors were quick to note that while edge computing sounds promising there are lots of challenges regarding interoperability and standardization. The authors specifically call out data abstraction as one pain point given the multitude of sources available at the edge. Using IoT sensors as an example, there could be hundreds of thousands of IoT devices, how can we standardize the data model to address the needs for all those devices? The authors end with recommending more research in the field specifically noting the difference in computing power in the cloud versus the edge. The paper does an excellent job of curating a comprehensive list of case studies. Use cases such as smart homes, smart cities, and cloud offloading are both practical and generate tangible benefits of edge computing. Additionally, the paper is upfront about the key challenges edge computing faces including data abstraction and security/privacy. All these play into the clarity of the paper itself. The authors present a concise and clear vision for the paper, outlining the role edge computing will play in the future for IoT. I wish the paper addressed the security/privacy concerns in a bit more detail. They’re addressed as key areas needing improvement, but no solution is proposed. The paper has somehow tied itself to the IoT use cases while ignoring other possible use cases such as disaster recovery, manufacturing, etc. Another topic that roughly covered was the savings on bandwidth and cost, the authors don’t follow it up with a discussion on how the edge computing paradigm would affect the economy specifically for business and service providers.
