In this talk, we will first discuss "Adaptive Overload Control for
Busy Internet Services" by Matt Welsh, then I will talk about some
ideas for our related ongoing work on "VM-friendly Adaptive Resource
Management". In Matt's paper, they present an adaptive admission
control mechanism for managing overload in Internet services. Through
monitoring the 90th-percentile response time of the requests and
controlling the rate of their admission, the service can manage
overload by filtering those requests that lead to resource
bottleneck. They evaluate their mechanism using a web-based email
service and a simple web server benchmark. Related to Matt's work, we
address efficiency and fairness issues related to resource
allocation. We propose an application-level adaptive resource
management framework based on its threading model. We capitalize on
this through developing a Friendly Virtual Machine framework
(VM-Friendly). Through adjusting the current executing thread number
and their sleeping times, each VM can share resources efficiently and
fairly. Performance evaluation is on progress.
