Flexible, Reliable, Distributed Software

Still Using Patterns and Agile Development, 2nd Edition

About the Book

Flexible, Reliable, Distributed Software continues the tradition from the original book Flexible, Reliable Software - Using Patterns and Agile Development, by Henrik Bærbak Christensen, CRC Press 2010. It puts emphasis on the architectural challenges facing developers when tackling distributed object-oriented programming, and presents a solution, the Broker pattern. It is treated both at the overview level, as well as at the code level. And of course, the tradition of emphasis on testing as a means to produce reliable software, is continued in this treatment. Finally, the REpresentational State Transfer architecture is presented and of course implemented.
