Performance Analysis of Aspect Oriented Programming for Cloud Service Monitoring

Monitoring is an important task in managing a Cloud Computing environment. But its implementation may result in added software complexity and altering of the offered cloud services. In this paper we demonstrate a monitoring approach called AOP4CSM (Aspect Oriented Programming for Cloud Service Monitoring) which monitors the qualityof-service parameters and provides fault tolerance to the Software-as-a Service Layer. It is based on aspect oriented programming (AOP) and it modifies neither the server-side implementation nor the client-side implementation of the service. We demonstrate the efficiency of AOP by comparing the results obtained from three services – one without AOP, one with AOP and one with the monitoring built into the source code.
