With the advent of the new generation of Internet-based technology, in particular, web services, the automation of business activities that are distributed across multiple enterprises becomes possible. Business activities are different from traditional transactions in that they are typically asynchronous, loosely coupled, and long running. Therefore, extended transaction protocols are needed to coordinate business activities that span multiple enterprises. Existing extended transaction protocols typically rely on compensating transactions to handle exceptional conditions. In this paper, we identify a number of issues with compensation-based extended transaction protocols and describe a reservation-based extended transaction protocol that addresses those issues. Moreover, we define …

Modular applications, components, and services are all ways of describing the product of an organization's efforts to embody its capabilities in autonomous software modules. In fact, the integration of services using well-established workflow paradigms could amplify an organization's capabilities with the creation of a full-blown, inter-organizational system of systems. This is the essence of Web-scale workflows. Considering the recent popularity and acceptance of service-oriented technologies, the application of such distributed systems is only limited by imagination, but it's also important to understand existing research challenges and their implications to various Web-scale workflow domains.
