When the request rate exceeds capacity limits at the resource‐constrained edge, some functions need to be offloaded toward the cloud. In this article, we present an auction‐inspired approach in which application developers bid on resources while fog nodes decide locally which functions to execute and which to offload in order to maximize revenue. Unlike many current approaches to function placement in the fog, our approach can work in an online and decentralized manner. We also present our proof‐of‐concept prototype AuctionWhisk that illustrates how such an approach can be implemented in a real FaaS platform. Through a number of simulation runs and system experiments, we show that revenue for overloaded nodes can be maximized without dropping function requests.en004 Datenverarbeitung; Informatikdistributed schedulingfog computingfunction‐as‐a‐serviceserverless computingArticle2022-06-141097-024X
