Hands-On Cloud Development with WildFly

By: Tomasz Adamski

Overview of this book

The book starts by introducing you to WildFly Swarm—a tool that allows you to create runnable microservices from Java EE components. You’ll learn the basics of Swarm operation—creating microservices containing only the parts of enterprise runtime needed in a specific case. Later, you’ll learn how to configure and test those services. In order to deploy our services in the cloud, we’ll use OpenShift. You’ll get to know basic information on its architecture, features, and relationship to Docker and Kubernetes. Later, you’ll learn how to deploy and configure your services to run in the OpenShift cloud. In the last part of the book, you’ll see how to make your application production-ready. You’ll find out how to configure continuous integration for your services using Jenkins, make your application resistant to network failures using Hystrix, and how to secure them using Keycloak. By the end of the book, you’ll have a functional example application and will have practical knowledge of Java EE cloud development that can be used as a reference in your other projects.

In this chapter, we've shown how you can use distributed security protocols to secure your cloud applications using our practical example.

We started this chapter by introducing concepts based on distributed authentication and authorization: the rationale for tokens and how they can be obtained and used. Later, we introduced basic information about a concrete distributed security protocol: OpenID Connect.

In the practical section, we used the Keycloak SSO server to secure the cart service in the Petstore application.

In the, we will discuss how do deal with an unreliable network problem using a circuit breaker pattern; specifically, the Hystrix library.
