Cloudy with a Chance of Load Spikes: Admission Control with Fuzzy Risk Assessments
2013 (English)In: 6th IEEE International Conference on Utility and Cloud Computing, 2013, 155-162 p.Conference paper (Refereed)
Elasticity is key for the cloud paradigm, wherethe pay-per use nature provides great flexibility for end-users.However, elasticity complicates long-term capacity planning forcloud providers as the exact amount of resources requiredover time becomes uncertain. Admission control techniques arethus needed to handle the trade-off between resource utilizationand potential overload. We define a set of admission controlalgorithms that combine risk assessment methods with a fuzzyaggregation framework. An experimental evaluation using amixture of bursty and steady applications demonstrate that ouralgorithms can increase resource utilization by a factor of twowhile limiting overload problems to a few percent.
