Distributed Systems Patterns

Table 5.1 lists the patterns included in the Distributed Systems patterns cluster, along with the problem statements and associated implementations that serve as a roadmap to the patterns.

Table 5.1: Distributed Systems Patterns

Pattern	Problem	Associated implementations
Broker	How can you structure a distributed system so that application developers don’t have to concern themselves with the details of remote communication?	Implementing Broker with .NET Remoting Using Server-Activated Objects Implementing Broker with .NET Remoting Using Client-Activated Objects
Data	How do you preserve the simple semantics of a procedure call interfeace without being subject to the latency issues inherent in remote communication?	Implementing Data Transfer Object in .NET Transfer with a DataSet Object Implementing Data Transfer Object in .NET with a Typed DataSet
Singleton	How do you make an instance of an object globally available and guarantee that only one instance of the class is created?	Implementing Singleton in C#

Note

The scope for this pattern cluster does not currently include message-oriented middleware, integration of multiple applications, or service-oriented architectures. These topics are extremely important and are part of the overall pattern language, but do not appear in this initial release.
