Building Microservices with Spring

Overview of this book

Getting Started with Spring Microservices begins with an overview of the Spring Framework 5.0, its design patterns, and its guidelines that enable you to implement responsive microservices at scale. You will learn how to use GoF patterns in application design. You will understand the dependency injection pattern, which is the main principle behind the decoupling process of the Spring Framework and makes it easier to manage your code. Then, you will learn how to use proxy patterns in aspect-oriented programming and remoting. Moving on, you will understand the JDBC template patterns and their use in abstracting database access. After understanding the basics, you will move on to more advanced topics, such as reactive streams and concurrency. Written to the latest specifications of Spring that focuses on Reactive Programming, the Learning Path teaches you how to build modern, internet-scale Java applications in no time. Next, you will understand how Spring Boot is used to deploying serverless autonomous services by removing the need to have a heavyweight application server. You’ll also explore ways to deploy your microservices to Docker and managing them with Mesos. By the end of this Learning Path, you will have the clarity and confidence for implementing microservices using Spring Framework. This Learning Path includes content from the following Packt products: • Spring 5 Microservices by Rajesh R V • Spring 5 Design Patterns by Dinesh Rajput

Microservices benefits

Microservice offers a number of benefits over the traditional multi-tier monolithic architectures. This section explains some of the key benefits of the microservices architecture approach.

Supports polyglot architecture

With microservices, architects and developers get flexibility in choosing the most suitable technology and architecture for a given scenario. This gives the flexibility to design better fit solutions in a more cost-effective way.

Since microservices are autonomous and independent, each service can run with its own architecture or technology, or different versions of technologies.

The following image shows a simple, practical example of polyglot architecture with microservices:

There is a requirement to audit all system transactions and record transaction details such as request and response data, users who initiated the transaction, the service invoked, and so on.

As shown in the preceding diagram, while core services like Order microservice and Product...
