Optimal Aggregation Policy for Reducing Tail Latency of Web Search

Jeong-Min Yun, Yuxiong He, Sameh Elnikety, Shaolei Ren
2015 Proceedings of the 38th International ACM SIGIR Conference on Research and Development in Information Retrieval - SIGIR '15  
Beginning with a single aggregator, we formally prove the optimality of our policy: It achieves the offline optimal result without knowing future responses of ISNs.  ...  Designing an aggregation policy is, however, challenging: Response latency among queries and among ISNs varies significantly, and aggregators lack of knowledge about when ISNs will respond.  ...  This is a common objective in many prior studies [11, 20, 22] as well as in real systems.  ...

Hedge Your Bets: Optimizing Long-term Cloud Costs by Mixing VM Purchasing Options [article]

Pradeep Ambati, Noman Bashir, David Irwin, Mohammad Hajiesmaili, Prashant Shenoy
2020 arXiv   pre-print
To address the problem, we design policies to optimize long-term cloud costs by selecting a mix of VM purchasing options based on short- and long-term expectations of workload utilization.  ...  Our results show that our policies incur a cost within 41% of an optimistic optimal offline approach, and 50% less than solely using on-demand VMs.  ...  IMPLEMENTATION We implemented both the optimistic offline approach ( §III-A) and practical online approach ( §III-B) in Python.  ...
