Characterizing, modeling, and generating workload spikes for stateful services

Peter Bodik, Armando Fox, Michael J. Franklin, Michael I. Jordan, David A. Patterson
2010 Proceedings of the 1st ACM symposium on Cloud computing - SoCC '10  
A popular approach is to create a workload model and generate synthetic workload, however, there exists no characterization and model of stateful spikes.  ...  Evaluating the resiliency of stateful Internet services to significant workload spikes and data hotspots requires realistic workload traces that are usually very difficult to obtain.  ...  This suggests that "stress testing for spikes" (especially for stateful services) is more subtle and involves more degrees of freedom than previously thought.  ...

Model-Switching: Dealing with Fluctuating Workloads in Machine-Learning-as-a-Service Systems

Jeff Zhang, Sameh Elnikety, Shuayb Zarar, Atul Gupta, Siddharth Garg
2020 USENIX Workshop on Hot Topics in Cloud Computing  
However, existing service ML serving systems have trouble dealing with fluctuating workloads and either drop requests or significantly expand hardware resources in response to load spikes.  ...  We implement Model-Switching within Clipper, a state-of-art DNN model serving system, and demonstrate its advantages over baseline approaches.  ...  Acknowledgements The authors would like to thank Jonathan Mace, as well as the anonymous reviewers for their time, suggestions, and valuable feedback.  ...

Evaluating Server Capacity for Streaming Media Services [chapter]

Beomjoo Seo, Michele Covell, Mirjana Spasojevic, Sumit Roy, Roger Zimmermann, Leonidas Kontothanassis, Nina Bhatti
2008 Lecture Notes in Business Information Processing  
In this study, we propose a more general, procedural methodology that characterizes a single system's streaming capacity and derives a prediction model that is applicable for any type of workload imposed  ...  Some of these goals conflict and motivate the development of precise and accurate models that predict the system states under extremely diverse workloads on-the-fly.  ...  While such generalized workload model helps to understand the average behavior of a streaming server, it usually fails to detect whether the server is saturated.  ...
