Software Architecture with Spring 5.0

By: René Enríquez, Alberto Salazar

Overview of this book

Spring 5 and its ecosystem can be used to build robust architectures effectively. Software architecture is the underlying piece that helps us accomplish our business goals whilst supporting the features that a product demands. This book explains in detail how to choose the right architecture and apply best practices during your software development cycle to avoid technical debt and support every business requirement. Choosing the right architecture model to support your business requirements is one of the key decisions you need to take when a new product is being created from scratch or is being refactored to support new business demands. This book gives you insights into the most common architectural models and guides you when and where they can be used. During this journey, you’ll see cutting-edge technologies surrounding the Spring products, and understand how to use agile techniques such as DevOps and continuous delivery to take your software to production effectively. By the end of this book, you’ll not only know the ins and outs of Spring, but also be able to make critical design decisions that surpass your clients’ expectations.

Implementing FaaS with Spring Cloud Functions


Under the umbrella of Spring projects, you will find the Spring Cloud Function project (https://cloud.spring.io/spring-cloud-function/), which is designed to implement applications using a serverless architecture model.

Using Spring Cloud Function, we can code functions that can be launched on different cloud providers that support FaaS. There's no need to learn something new from scratch, because all of the core concepts and main features of Spring Framework, such as autoconfiguration, dependency injection, and built-in metrics, are applied in the same way.

Once a function has been coded, it can be deployed as a web endpoint, a stream processor, or simple tasks that are triggered by certain events or via a scheduler.

Looking at an example of an SPA, we can implement an application using third-party services, the existing REST API, and custom functions. The following diagram illustrates how an application can be created by using all of the previously...
