Microservice Patterns and Best Practices

By: Vinicius Feitosa Pacheco

Overview of this book

Microservices are a hot trend in the development world right now. Many enterprises have adopted this approach to achieve agility and the continuous delivery of applications to gain a competitive advantage. This book will take you through different design patterns at different stages of the microservice application development along with their best practices. Microservice Patterns and Best Practices starts with the learning of microservices key concepts and showing how to make the right choices while designing microservices. You will then move onto internal microservices application patterns, such as caching strategy, asynchronism, CQRS and event sourcing, circuit breaker, and bulkheads. As you progress, you'll learn the design patterns of microservices. The book will guide you on where to use the perfect design pattern at the application development stage and how to break monolithic application into microservices. You will also be taken through the best practices and patterns involved while testing, securing, and deploying your microservice application. At the end of the book, you will easily be able to create interoperable microservices, which are testable and prepared for optimum performance.

Microservice communication


We know that there are two communication models in the architecture of microservices— synchronous and asynchronous. When applying the chained design pattern, we preferentially use synchronous communication because the consumer of the application is waiting for a complete response that will be composed of data from one or more microservices. If the communication model is not synchronous, the response composition control could have a callback system, which grows in complexity and compromises scalability.

It is important to understand that, with the synchronous communication model, we are creating a blocking communication model. We say that the synchronous communication model is blocking because the consumer of the application is waiting for a response that is being composed in a communication chain between microservices. The longer the communication chain between microservices, the longer the consumer's wait for the application will be.

With the synchronous communication...
