Samenvatting

There are no easy decisions in software architecture. Instead, there are many hard parts-difficult problems or issues with no best practices-that force you to choose among various compromises. With this book, you'll learn how to think critically about the trade-offs involved with distributed architectures.

Architecture veterans and practicing consultants Neal Ford, Mark Richards, Pramod Sadalage, and Zhamak Dehghani discuss strategies for choosing an appropriate architecture. By interweaving a story about a fictional group of technology professionals-the Sysops Squad-they examine everything from how to determine service granularity, manage workflows and orchestration, manage and decouple contracts, and manage distributed transactions to how to optimize operational characteristics, such as scalability, elasticity, and performance.

By focusing on commonly asked questions, this book provides techniques to help you discover and weigh the trade-offs as you confront the issues you face as an architect.

- Analyze trade-offs and effectively document your decisions
- Make better decisions regarding service granularity
- Understand the complexities of breaking apart monolithic applications
- Manage and decouple contracts between services
- Handle data in a highly distributed architecture
- Learn patterns to manage workflow and transactions when breaking apart applications

Over Pramond Sadalage

Pramod Sadalage is principal consultant at ThoughtWorks where he enjoys the rare role of bridging the divide between database professionals and application developers. He is usually sent in to clients with particularly challenging data needs, which require new technologies and techniques. In the early 00's he developed techniques to allow relational databases to be designed in an evolutionary manner based on version-controlled schema migrations. He is the co-author of Refactoring Databases, and continues to speak and write about the insights he and his clients learn.
