SUMMARY:The Hidden Cost of the Edge: A Performance Comparison of Edge and 
 Cloud Latencies
DESCRIPTION:Paper\n\nThe Hidden Cost of the Edge: A Performance Comparison
  of Edge and Cloud Latencies\n\nAli-Eldin, Wang, Shenoy\n\nEdge computing 
 has emerged as a popular paradigm due to its ability to offer lower networ
 k latencies to end-users. In this paper, we argue that despite its lower n
 etwork latency, the resource-constrained nature of the edge can result in 
 higher end-to-end latency, especially at higher utilizations, compared to 
 cloud data centers. We study this edge performance inversion problem throu
 gh an analytic comparison of edge and cloud latencies and analyze conditio
 ns under which the edge can yield worse performance than the cloud. For ve
 rification we conduct experimental comparisons of the edge and the cloud l
 atencies using a realistic application and real cloud workloads. Our resul
 ts show that the edge queuing delays can offset the benefits of lower netw
 ork latencies, and even result in performance inversion. We finally discus
 s practical implications of our results and provide insights into how appl
 ication designers/service providers should design edge applications and sy
 stems to avoid these pitfalls.\n\nTag: Reproducibility Badge, Resource Man
