WOSP-C 2020: Workshop on Challenges and Opportunities in Large-Scale Performance: Welcoming Remarks

It is my great pleasure to welcome you to WOSP-C 2020, the Workshop on Challenges and Opportunities in Large Scale Performance. Our theme this year relates to the use of analytics to interpret system performance and resource usage measurements that can now be gathered rapidly on a large scale. Our four invited speakers hail from industry. All three presentations in the first session and the last presentation in the second session deal with modeling and measurement to automate the making of decisions about system configuration or the recognition of anomalies, especially for cloud-based systems. The other two papers in the second session address measurement and modeling issues at a granular level. These topics are highly relevant to the issues systems architects and other stakeholders face when deploying systems in the cloud, because doing so need not guarantee good performance. The recent emergence of the ability to gather vast numbers of performance and resource usage measurements facilitates the informed choice of target cloud platforms and their configurations. The presentations in this workshop deal with various aspects of how this can be achieved.
