 | Book Download: Exploring CQRS and Event Sourcing |
A journey into high scalability, availability and maintainability with Windows Azure
Authors: Dominic Betts, Julián Domínguez, Grigori Melnik, Fernando Simonazzi, Mani Subramanian.
Foreword by Greg Young.
This guide is focused on building highly scalable, highly available, and maintainable applications with the Command & Query Responsibility Segregation and the Event Sourcing architectural patterns. It presents a learning journey, not definitive guidance. It describes the experiences of a development team with no prior CQRS proficiency in building, deploying (to Windows Azure), and maintaining a sample real-world, complex, enterprise system to showcase various CQRS and ES concepts, challenges, and techniques. The development team did not work in isolation; we actively sought input from industry experts and from a wide group of advisors to ensure that the guidance is both detailed and practical.
The CQRS pattern and event sourcing are not mere simplistic solutions to the problems associated with large-scale, distributed systems. By providing you with both a working application and written guidance, we expect you'll be well prepared to embark on your own CQRS journey.
The guide is split into three distinct sections that you can read independently: a description of the journey we took as we learned about CQRS, a collection of CQRS reference materials, and a collection of case studies that describe the experiences other teams have had with the CQRS pattern.
