Monitoring Users in Cloud Computing: Evaluating the Centralized Approach

So far, monitoring in cloud computing mostly tends to focus only on QoS and Service Level Agreements. However, if we tend to monitor user activities on clouds we have to look at a centralized approach. Having a centralized monitoring system in cloud computing is becoming more and more necessary, it is worthwhile to address this kind of monitoring in the cost and performance angles also. The performance and cost studies will not be appropriate without a tight comparison of various implementation and architectural possibilities. A Simulation is made so as to reveal the best options based on cost and performance.
