Cloud Native Integration with Apache Camel

Address the most common integration challenges, by understanding the ins and outs of the choices and exemplifying the solutions with practical examples on how to create cloud native applications using Apache Camel. Camel will be our main tool, but we will also see some complementary tools and plugins that can make our development and testing easier, such as Quarkus, and tools for more specific use cases, such as Apache Kafka and Keycloak.

You will learn to connect with databases, create REST APIs, transform data, connect with message oriented software (MOMs), secure your services, and test using Camel. You will also learn software architecture patterns for integration and how to leverage container platforms, such as Kubernetes. This book is suitable for those who are eager to learn an integration tool that fits the Kubernetes world, and who want to explore the integration challenges that can be solved using containers.

WHAT YOU WILL LEARN

* Focus on how to solve integration challenges
* Understand the basics of the Quarkus as it’s the foundation for the application
* Acquire a comprehensive view on Apache Camel
* Deploy an application in Kubernetes
* Follow good practices

WHO THIS BOOK IS FOR

Java developers looking to learn Apache Camel; Apache Camel developers looking to learn more about Kubernetes deployments; software architects looking to study integration patterns for Kubernetes based systems; system administrators (operations teams) looking to get a better understand of how technologies are integrated.

GUILHERME CAMPOSO is a solution architect. He started to use open source projects and completely fell in love with the OSS philosophy and potential, leading him to start working with an open source company in 2018. Throughout his more than 12-year career, starting as a Java developer, becoming a consultant and then an architect, Guilherme was able to acquire a vast experience helping customers from a great variety of business sectors, giving him a broad view on how integration and good software practices can help businesses to grow. Chapter 1: Welcome to Apache Camel

CHAPTER GOAL: Introduce readers to Apache Camel, it's basic concepts and contextualize everything with integration patterns. Also introduce other base tools as Quarkus and Maven.

SUB -TOPICS

1. Apache Camel basics

2. Quarkus basics

3. Introduction to Enterprise Integration Patterns

4. Hello World application (First Application)

Chapter 2: Developing REST Integrations

CHAPTER GOAL: Introduces the conversation on web services applications using REST, how to expose and how to consume those services. Also gives the first examples of unit testing.

4. Transaction control

Chapter 5: Messaging with Apache Kafka

CHAPTER GOAL: Introduces the reader to Message Oriented Middleware(MOM), which is a very common integration used. We dive into the architecture aspect of this kind of implementation, getting practical examples using Apache Kafka, another very popular Open Source project.

NO OF PAGES: Approximately 40 pages

SUB - TOPICS:

1. Message Oriented Middleware

2. Apache Kafka

3. Asynchronous integration

Chapter 6: Deploying application into Kubernetes

CHAPTER GOAL: Here we discuss the architectural aspects of deploying applications into Kubernetes, discussing micro services architecture, scalability, configuration and patterns as The Twelve-Factor Apps. We also learn how to configure the application and plugins to allow us to test and deploy the application in Kubernetes.

NO OF PAGES: Approximately 50 pages

SUB - TOPICS:

1. The Twelve-Factor Apps

2. Quarkus and Camel properties configuration

3. Quarkus plugins for Kubernetes Deployments

4. The main Kubernetes aspects to take into consideration for your architecture
