دانلود کتاب الگوهای میکروسرویس، ویرایش دوم

My goal is to make this material accessible regardless of your technology stack. You’ll get the most from this book if you’re already familiar with the basics of enterprise application architecture and design—concepts like three-tier architecture, web application design, relational databases, inter-process communication using REST or messaging, and basic application security. Since the first edition of Microservices Patterns was published in late 2018, I’ve had the privilege of working with countless organizations on their microservice journeys. I’ve delivered many talks and had countless conversations with teams about how to think about microservices, how to avoid common pitfalls, and how to solve the real-world challenges that arise when implementing these architectures. This second edition is a substantial update that reflects what I’ve learned over the past several years and includes new insights, and techniques for applying microservices effectively in today’s complex software environments. The second edition also has a sharper focus on fast flow — the continuous delivery of a stream of small changes and rapid feedback on each one – as the primary motivation for adopting microservices is to enable fast flow. In the first edition, I touched on this idea, but it wasn’t explicitly named. Since then, my thinking has become much more focused on the fast flow success triangle, which describes the three essential elements necessary to achieve fast flow: – Team Topologies – designing your organization to support independent teams – DevOps – principles and practices for delivering software rapidly, frequently, and reliably – Architecture – a loosely design-time coupled, highly testable, and deployable architecture that enables Team Topologies and DevOps practices. For some applications, a monolithic architecture is a good choice. But for larger applications developed by many teams, a microservice architecture is often the better option. Understanding the elements of the success triangle and the role of architecture is key to high-performance software delivery. The second edition also emphasizes the importance of architectural fundamentals. A solid grasp of architectural fundamentals is essential for understanding what the microservice architecture is, when to use it, and how to apply it effectively. Most notably, the book explains several important software architecture concepts, including the multi-dimensional nature of software architecture; different flavors of coupling and why loose coupling matters; and the concept of software quality attributes and how they can enable fast flow. Finally, I have significantly expanded the coverage of architectural decision-making techniques. You’ll learn how to decide between a monolithic and microservice architecture based on your specific context. I introduce the ten dark energy and dark matter forces that serve as essential criteria for evaluating and comparing candidate solutions to the many design problems you will encounter when defining a microservice architecture. You will also learn a step-by-step process for designing and evolving a microservice architecture.
