A Dynamic Complex Event Processing Architecture for Cloud Monitoring and Analysis

Cloud monitoring and analysis are challenging tasks that have recently been addressed by Complex Event Processing (CEP) techniques. CEP systems can process many incoming event streams and execute continuously running queries to analyze the behavior of a Cloud. Based on a Cloud performance monitoring and analysis use case, this paper experimentally evaluates different CEP architectures in terms of precision, recall and other performance indicators. The results of the experimental comparison are used to propose a novel dynamic CEP architecture for Cloud monitoring and analysis. The novel dynamic CEP architecture is designed to dynamically switch between different centralized and distributed CEP architectures depending on the current machine load and network traffic conditions in the observed Cloud environment.
