Chapter 4. Designing Distributed Applications
Now that we have delved into the principles and patterns of distributed application architecture, how can we best put them into practice? Using event-driven architecture with microservices has proven to be one of the best ways to translate business needs and model the application domain in a way that is in line with how distributed systems work, allowing applications to be ready for, and make the most out of, the cloud and edge. Let’s now take some time to discuss this in more detail.
Fundamental Principles of Microservices
Microservices have emerged as a powerful architectural pattern for building cloud applications, offering numerous advantages in terms of speed, efficiency, predictability, and safety. This approach has proven particularly effective in scaling organizations by allowing developers to decompose complex applications into discrete, decoupled services that communicate via well-defined protocols. This decomposition empowers individual teams to develop, deploy, and evolve their microservices independently, fostering agility and innovation.
Moreover, when implemented correctly, microservices provide an elegant solution to the challenges inherent in distributed systems. To harness the full potential of this architecture, you should adhere to five key principles:
-
Isolation of components
-
Autonomous operation
-
Single responsibility
-
Exclusive state ownership
-
Mobility with addressability
Let’s explore each of these ...
