DISTRIBUTED OBJECT COMPUTING

摘要

Distributed Object Computing is a paradigm shift within the Client/Server revolution.rnObjects breakup the client and server sides of an application into smart plug & playrncomponents, which can interact across networks. Enterprise systems are rapidly shiftingrntowards the distributed object technology resulting in the development of faster, betterrnand cheaper integrated component based applications. Running the right components inrnthe right places benefits the user and optimizes the use of network and computerrnresources. Distributed applications offer more scalability than monolithic applicationsrnand also provide a great deal of flexibility in deployment. Developers are turning torncreating components rather than monolithic applications to free themselves from slow,rnexpensive application development, and to build up a portable, reusable code base. Thernprerequisites for successful component based software development include technologyrnbase in form of component models, a selection of commercial of the shelf components,rnintegration techniques, run-time environments, development methods and developmentrntools. Developing distributed enterprise applications presents some interesting challengesrnin designing and deploying applications with different hardware and software platforms.rnChoosing the model(s) and achieving interoperability among multiple models add morerncomplexity to the issue. Different models/architectures have been emerged to standardizernthe interoperability between objects distributed in network.rnThis paper presents a technical overview of distributed objects, their evolution and thernvarious standards-based architectures emerged to implement the distributed objectcomputingrnmodel. The objective is to highlight the potential of distributed objects and thernenabling technologies in a heterogeneous computing environment.
