Abstract

A modern service-based application (SBA) operates in a cross-cloud, highly dynamic environment while comprises various components at different abstraction levels that might fail. To support cross-level SBA adaptation, a cross-cloud Service Level Objective (SLO) monitoring and evaluation system is required, able to produce the right events that must trigger suitable adaptation actions. While most research focuses on SBA monitoring, SLO evaluation is usually restricted in a centralised, single-cloud form, not amenable to heavy workloads that could incur in a complex SBA system. Thus, a fast and scalable event generation and processing system is needed, able to scale well to handle such a load. Such a system must address the cross-level event composition, suitable for detecting complex problematic situations. This paper closes this gap by proposing a novel complex event processing framework, scalable and distributable across the whole SBA architecture. This framework can cover any kind of event combination, no matter how complex it is. It also supports event pattern management while exploits a publish-subscribe mechanism to: (a) synchronise with the modification of adaptation rules directly involving these event patterns; (b) enable the decoupling from an SBA management system.
