Serverless computing provides a small run-time container to execute lines of codes; relieving developers from the management of the underlying infrastructure. In a serverless computing architecture, all administration operations are handled by cloud service providers. Thanks to its lightweight nature, ease of management, and ability to scale quickly, serverless computing is becoming a top choice for application development in the Internet of Things (IoT) community. However, like every new technology, there are limitations as well as advantages. For example, the highly-distributed, loosely coupled nature of Serverless applications can cause latency issues. Therefore, the advantages of a serverless architecture may come with a performance cost. To clear up this suspicion, this paper examines the performance implications of deploying IoT applications using a serverless infrastructure in comparison to deployments …
