Domain Analysis of Enterprise Service-Oriented Distributed System Computational Attributes using System Execution Modeling Tools

Challenges of enterprise distributed system development. Enterprise distributed systems (such as air traffic management systems, cloud computing centers, and shipboard computing environments) are steadily increasing in size (e.g., lines of source code and number of hosts in the target environment) and complexity (e.g., application scenarios). To address challenges associated with developing next-generation enterprise distributed systems, service-oriented middleware [Pezzini:07] is becoming the de facto standard for developing such systems. Service-oriented middleware increases the level of abstraction for software development so distributed system developers focus on the system’s “business-logic” instead of wrestling with low-level implementation details, such as development and configuration, resource management, fault tolerance. Moreover, service-oriented middleware promotes reuse of the system’s “business-logic” across different application domains, which helps reduce (re)invention of core intellectual property.
