QUEUE-BASED SYSTEM ARCHITECTURE (QBSA) explains a style of system architecture that effectively supports collaboration of distributed, internal and external systems prevalent in the modern enterprise.
An example of a system that requires collaboration of multiple internal and external systems is the Obamacare website. The Obamacare website must consult with a bevy of State and private health insurance systems to provide accurate insurance quotes to its patrons. And it must to do so for millions of website visitors in a timely fashion.
To illustrate QBSA, the book walks through one possible queue-based system design of a healthcare insurance exchange website that can efficiently and reliably prepare health insurance quotes for a large number of customers. Most of the work in a queue-based system is handled asynchronously in the background by autonomous processes. Message queues play an essential role in queue-based systems. A well-designed queue-based system can prepare a response for a complicated request within a matter of few seconds. Some of the topics covered in this book include:
- How to process commands asynchronously in the background?
- How to monitor and troubleshoot a queue-based system?
- How to scale a queue-based system?
- How to add new functionality to a queue-based system?
- How does a queue-based system participate in an Enterprise Service Bus (ESB)?
Equipped with the information in this book, you will be able to confidently design scalable, fault-tolerant distributed systems.
