The explosive growth in global networking infrastructures has created the opportunity to construct systems involving large number of independent and widely-distributed computational components. Administrative and operational autonomy considerations imply that the actual establishment of agreements regarding all aspects of component interaction must be explicitly declared and effectively formed. Moreover, since agreements may evolve over time, their representation needs to be highly tailorable. Design autonomy considerations imply the need to interoperate between pre-existing components, yet not enforce a fixed interoperability standard. The HADAS system addresses both concerns by providing a model and a corresponding programmable interface to component interoperability. Specifically, it provides an integration framework in which components "live", a peer-based configuration model for forming agreements and interconnections between components, and a coordination language for explicitly programming the actual desired distributed computation using these components. The framework rests on an underlying reflective object model that supports mutability and mobility, and an infrastructure that provides object interconnectivity, security and persistence. HADAS is fully implemented in Java and comes with a full programming environment for developing and executing network-centric applications.

Capacity planning in a large-scale distributedcomputing environment such as that found in a major university-based medical center offers many challenges to traditional approaches. Vanderbilt University Medical Center (VUMC) operates a class B Internet domain, including an IBM mainframe and a large number of server and client machines. In this environment, user demands for access to distributedcomputing resources drive the development of new applications. Like many complex organizations, VUMC is in the process of implementing an architecture for computing across the enterprise to meet those demands and to provide the beginnings of infrastructure tools for capacity planning. The new architecture presents increased challenges for capacity planning. The user demands at VUMC, the architectural solutions, and the capacity planning challenges that these changes bring with them are described.

One approach to understanding the cost of an operation in a client-server environment is to follow the path of an operation through all components of the system, requiring timing synchronization across system boundaries. An alternative approach looks at each system component individually, simplifying the application instrumentation. This paper presents the implementation of this alternative approach in the characterization of a distributed messaging application. First the authors describe a prototype instrumentation Application Programming Interface (API) and the test application environment, then present the test methodology and the analysis of the results.

The challenges facing I/S management today are numerous, including cost management, responsiveness to business needs, system availability, efficiency, effectiveness, and employee/worker productivity. Client/Server Server systems are often employed to address these concerns, as distributed systems are thought of as being small, inexpensive, easy to scale, and easy to manage. This paper outlines critical issues for senior management as well as recommendations to effectively manage distributed systems. Examples are included of what can be done and what happens if proper focus is not applied.
