> Improvements to Autoscaling in Apache Stratos
> ---------------------------------------------
>
> Key: STRATOS-488
> URL: https://issues.apache.org/jira/browse/STRATOS-488
> Project: Stratos
> Issue Type: Improvement
> Components: Autoscaler
> Reporter: Lahiru Sandaruwan
> Labels: gsoc2014, mentor
>
> You can find some details about autoscaling from [1] and [2].
> 1. Improve Autoscaling to predict the number of instances required in the
> next time interval.
> Currently we predict the load for next time interval. Then we use a threshold
> to decide on scale up or down. Factors that we are considering are the
> requests in flight at load balancer and Load average and memory consumption
> of cartridge instance.
> Best approach would be to decide the number of instances that will be
> required to handle the load in next time interval.
> 2. Predict the load according to a schedule defined by end user
> This aspect will be needed to handle seasonal load expectations.
> E.g. High load on Christmas and new year period.
