This paper presents a flexible, portable, and transparent solution for strong mobility of composed Web services relying on policy-oriented techniques. The proposed approach provides a checkpoint solution based on automatic code instrumentation using correct source code transformation rules. This checkpoint technique permits to save the execution state of a(More)
In this paper, we address the problem of strong mobility of orchestrated Web services. In particular, we focus on the case where the partner Web services are also orchestrated. For such services, we employ an Aspect oriented approach based on checkpoint/rollback mechanisms which enables the orchestration process to migrate to another host and resume its(More)
Cloud computing systems are rapidly growing in scale and complexity. They are also changing dynamically as a result of dynamic addition and removal of system components, different execution environments, common updates and upgrades, runtime repairs, mobility of devices and more. Such large-scale, complex and dynamic cloud environments are prone to failures(More)
