Real-Time Dynamic Cloud Monitoring System ...

In order to solve the problem that there is no suitable SLA system for cloud environment, a real-time dynamic cloud monitoring system has been proposed based on SLA, consisting of SLA agreement information database, distributed cluster data monitoring system, distributed runtime monitoring system, QoS knowledge base and resource scheduler. A prototype of the proposed system has been developed as well as the test has been conducted. The experimental results show that this system, while monitoring the cloud, can reduce the risk of a SLA agreement violation threats by taking actions ahead. In addition, it has a relatively high reliability and scalability.
