Abstract: A problem observed in cloud environments is the assurance of Quality of Service (QoS) in the execution of applications. In the context of batch applications, a common goal is ensuring deadline compliance. However, estimating the required amount of resources to assure execution deadline may be difficult and prone to underallocations or superallocations. An alternative is modifying the amount of allocated resources in case the progress is not satisfactory, using horizontal or vertical scaling. Following this strategy, this work proposes a provisioning method based on PID controllers and vertical scaling for batch applications. To evaluate the proposed provisioning method on assuring QoS, we executed two microbenchmarks and one Big Data application on a real cloud infrastructure where the provisioning was controlled by our method. Results show that the provisioning method using the Proportional-Derivative controller is effective on ensuring QoS regarding deadline compliance, allocation smoothness and resource efficiency, though it requires additional adjusts when provisioning resources to applications with non-linear progress.
