An Effective Framework To Monitor Service Level Agreements In Cloud Computing Environment

Abstract

Cloud computing is a new technology that most of the big organizations are adopting today all over the world. This technology is very important for service consumers to save their time, cost minimization, save human power and they can get services being anywhere at any time and pay per use as well. However there are different kinds of problems in cloud computing environment like service level agreement is violated in most of the service providers when services are delivered. How to consider SLA in a general way for different cloud environments and SLA monitoring problems. In this research we had solved the problems we specified in our scope of the research. We have developed SLA Monitoring framework to solve the identified problems. The framework contains SLA fetcher, Running SLA, Monitoring agent, cloud provider and consumer and cloud services delivery models. We have implemented our prototype using CloudSim on java net beans, MySQL database for creating necessary databases and tables for our research, E_Draw max for destining purposes. We have used three scenarios to evaluate our prototype. The first scenario is giving the resources the same with SLA. The second scenario is we gave less resources than the SLA and in the third scenario we gave more resources than SLA. In the first case there is no violation, but there is violation in the second and third scenario.
