Cloud monitoring: A review, taxonomy, and open research issues

Cloud monitoring supervise and manages the operational work-flow and processes within cloud data centers to ensure its performance capacity and capabilities. It assists smooth running of cloud services and minimizes the probability of SLA violation. Based on the requirements of cloud users and providers, it has various aspects, purposes, and utilization. For instance, a cloud provider exploits a monitoring tool to efficiently utilize underlying resources of a cloud. The unavailability of a comprehensive survey covering various aspects of cloud monitoring including purposes, communication models, performance overhead, scalability and architectural designs motivated to review this topic. This paper comprehensively reviews state-of-the-art cloud monitoring solutions for private and public clouds. It proposes a thematic taxonomy to classify the existing cloud monitoring solutions based on a set of parameters. It proposes a detailed analysis of existing solutions based on the proposed thematic taxonomy to highlight the commonalities and differences in existing solutions. Lastly, it puts forward a set of open research issues in this domain of research that hinders proposing optimal cloud monitoring solutions. This paper will help researchers of this domain to understand the problems clearly in this research area.
