About the Book
Constructing Large Scale Enterprise Systems With Ruby And Rails : A Bitcoin Exchange Implementation
This book discusses the architecture and implementation of large scale enterprise systems with Ruby and Rails. Architectural patterns for designing highly concurrent, scalable and loosely coupled systems are discussed. A Bitcoin Exchange using these patterns is implemented. Among the topics covered are:
• The use of design patterns which are very useful in the enterprise context
• Using service objects
• Using the the data context interaction pattern
• Building a fault tolerant system
• Using Facades and a Restful API in a large system
• Using concurrency in enterprise scale systems
• Decoupling enterprise systems with a message bus
• Implementing workflows with finite state machines
• Implementing locational transparency
• Internationalizing the application
These architectural patterns are applied to the construction of a Bitcoin Exchange.
This is primarily a book on architecture. Though the software implementation is in Ruby using the Rails framework, experienced developers should have no particular difficulty in following the code implementation and gaining a good understanding of the Ruby language and the Rails framework in the process.
