Ebook: Microservices with Spring Boot and Spring Cloud - Build resilient and scalable microservices using Spring Cloud, Istio, and Kubernetes

No familiarity with microservices architecture is required to get started with this book.

With this book, you'll learn how to efficiently build and deploy microservices. This new edition has been updated for the most recent versions of Spring, Java, Kubernetes, and Istio, demonstrating faster and simpler handling of Spring Boot, local Kubernetes clusters, and Istio installation. The expanded scope includes native compilation of Spring-based microservices, support for Windows & Mac, and an introduction to Helm 3 for packaging and deployment. A revamped security chapter now follows the OAuth 2.1 specification and makes use of the newly launched Spring Authorization Server from the Spring team.

Starting with a set of simple cooperating microservices, you'll add persistence and resilience, make your microservices reactive, and document their APIs using Swagger/OpenAPI.

You’ll understand how fundamental design patterns are applied to add important functionality, such as service discovery with Netflix Eureka and edge servers with Spring Cloud Gateway. You’ll learn how to deploy your microservices using Kubernetes and adopt Istio. You'll explore centralized log management using the Elasticsearch, Fluentd, and Kibana (EFK) stack and monitor microservices using Prometheus and Grafana.

By the end of this book, you'll be confident in building microservices that are scalable and robust using Spring Boot and Spring Cloud.

-------------------------------

Build reactive microservices using Spring Boot

Develop resilient and scalable microservices using Spring Cloud

Use OAuth 2.1/OIDC and Spring Security to protect public APIs

Implement Docker to bridge the gap between development, testing, and production

Deploy and manage microservices with Kubernetes

Apply Istio for improved security, observability, and traffic management

Write and run manual and automated microservice tests with JUnit, testcontainers, Gradle, and bash

---------------------------------

This book is intended for Java and Spring developers and architects who want to learn how to build microservice landscapes from the ground up and deploy them either on-premises or in the cloud, using Kubernetes as a container orchestrator and Istio as a service mesh.
