摘要

Auto-scaling systems help provisioning resources on demand which helps tap into the elastic nature of the cloud. Theapplications hosted on the cloud tend to face workload surges which causes the response to be slow or denied. To tackleprovisioning resources on demand there are reactive and proactive strategies in place. The topic of interest is the proactivestrategies which uses a quantified metric as an input to provision resources before the demand arises. The quantified metricis the prediction obtained as a result of analysing the historical data of a application. This paper focuses using historicaldata of requests served by a web application to obtain a forecast value. The forecast value is the quantified metric whichinfluences the scaling decisions. Conclusions are drawn about the accuracy of the metric based on prediction intervalsalong with the varied ways of forecast.
