Optimal load balancing for heterogeneous clusters
(January 2015 - present)
Large-scale cluster deployments are common in today's cloud-hosted application environments. Online service providers such as Amazon, Facebook and Google often employ clusters of thousands of nodes for serving web requests.
These online services often handle thousands of customer requests per second.
However, developing efficient load balancers for large, distributed
clusters is challenging for several reasons: (i) large clusters
require numerous scheduling decisions per second, (ii) such
clusters typically consist of heterogeneous servers that widely
differ in their computing power, and (iii) such clusters often
experience significant changes in load.
The goal of this project is to develop scalable, heterogeneity-aware load balancers. We will employ queueing-theoretic ideas to design simple yet adaptive load balancers that provide near-optimal performance.
