 <p>Majority of PaaS providers only used http traffic to auto scale or dynamic resource provisioning. It gives limitation on scaling non-http based application. But Apache Stratos auto scaler can take http traffic and non-http health data to do intelligent dynamic resource provisioning. Also its capable of dealing with these multiple factors run through scaling algorithm simultaneously. Inflight request count on Load Balancers, Load average, Memory consumption are some of factors and its easy to extend (benefit from clean unified communication) to any factors need to take care of the auto scaling.</p>
 <h2>Predicting future loads</h2>
 <p>Another important capability of Apache Stratos is predicting immediate future load, based on current health statistics. All cartridges, Load balances, health monitors are publishing health status into CEP (Complex Event Processor) via real time event bus. CEP will aggregate all these events and calculate first derivative, second derivative for a given time window frame and paas resulting streams to Auto scaler via reliable message bus.</p>
