Episode 63: A Pattern Language for Distributed Systems with Henney and Buschmann

Guest: Kevlin Henney and Frank Buschmann
Host: Markus
recorded at: OOP 2007

In this Episode we talked about the new POSA 4 book which has recently been published. We talk to two of the authors, Kevlin Henney and Frank Buschmann (the third author, Doug Schmidt was not available - and he had also been on the podcast a couple of times :-)). The book contains a pattern language for distributed systems. It contains 114 patterns that had been published before by many different other authors. The patterns have been rewritten to form a consistent language.

We basically talked through the different sections of the book, which gives a really good overview over the challenges and the solutions of building distributed systems. These sections include From Mud to Structure, Distribution Infrastructure, Event Demultiplexing and Dispatching, Interface Partitioning, Component Patitioning, Application Contrl, Concurrency, Synchronization, Object Interaction, Adaptazion and Extension, Modal Behaviour, Resource Management and finally, Database Access.

The book references several other previous works (as listed below). Interestingly, many of these referenced works and authors have also been discussed previously on the podcast. Here are the back references:

• Domain Driven Design, Eric Evans
• Messaging Patterns, Gregor Hohpe
• POSA 2 Patterns, Doug Schmidt
• Concurrency: Part 1, Part 2, Part 3 and the interview with Goetz and Holmes
• Remoting Patterns Part 1 and Part 2
• POSA3, Resource Management

Here are some of the books and publications mentioned in the discussion:

• POSA 1, 2, 3, 4, 5
• Server Component Patterns book, Remoting Patterns book
• Eric Evans's DDD book
• Martin Fowler's Analysis Patterns, Patterns of Enterprise Architecture
• Gregor Hohpe's Messaging book
