The Code Project - Distributed Command Pattern

The Code Project - Distributed Command Pattern - an extension of command pattern for connected systems - C# Programming

"Distributed Command Pattern is a pattern for connected systems which implements command pattern. It frees designers from thinking about the communication and helps them concentrate on implementing commands as if it is a regular desktop application. The framework takes care of the communication.

Distributed Command Pattern is a proposed pattern for solving the extra architectural design issues which need to be considered for connected systems than designing regular applications. The goal of this pattern is to “Have the same design for both standalone and connected systems”. This pattern allows developers to concentrate on designing a regular application following the Command Pattern [Gamma 1995] without ever thinking that this application is going to connect with other systems. This pattern frees a developer from thinking about the transport and communication protocol while designing the commands, and keeps the architecture simple. Designers need not worry about how to send necessary data to the server when some command gets executed and how to process received data from the server and then reflect on the UI of the connected applications. When a command gets executed locally on one running application, distributed design pattern takes care of the hurdles of executing the same command in all connected systems simultaneously in order to keep them in the same state. From a designer’s point of view, the architecture remains as simple as a regular desktop application designed using regular command pattern having no network awareness, yet it performs all the necessary communications in order to execute the commands on all connected applications as if the command has been invoked internally.

I want to take a much closer look at this. I need to build a highly distrubuted and scaleable processing system (i.e. everything runs on 1 machine or is spread across 150+...) for the next rev of a work system and really don't want to reinvent.
