Exceptions cause temporal failures of Web-based systems to deliver continuous and responsive end-to-end services. On cloud platforms, resource provisioning and administration become less explicit, which entails techniques that can act on exceptions according to known strategies. In this paper, we propose a middleware-based approach that encompasses a healing process that links available strategies...
Loosely coupled component communication driven by events is a key mechanism for building middleware-based applications that must achieve reliable qualities of service in an adaptive manner. In such a system, events that encapsulate state snapshots of a running system are generated by monitoring components. Hence, an event correlation service is necessary for correlating monitored events from multiple...
Composing adaptive and self-managing Web services needs plug-and-play architecture so that the deployment of control components does not require changes made to the Web services and the host middleware platforms. This is especially challenging for Web services running on COTS middleware platforms, such as Microsoft.Net. In this paper, we propose an architectural solution that introduces a management...
