With a variety of services rapidly evolving at all architectural levels of cloud computing, there is an increasing demand for a standardized way to coordinate their interactions. Business process management, that is, more general, the management of Web-service--based workflows, could satisfy this demand and, indeed, first corresponding offerings have gained instant popularity. While from a functional perspective, these Platform-as-a-Service (PaaS) solutions are already quite mature, their support for fault tolerance is still very limited, making them inapplicable for critical tasks.
