Overview of this book

Want to build and deploy microservices, but don’t know where to start? Welcome to Microservices with Spring Boot and Spring Cloud. This edition features 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 Mac and Windows with WSL2, 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. You’ll start with a set of simple cooperating microservices, then add persistence and resilience, make your microservices reactive, and document their APIs using OpenAPI. Next, you’ll learn 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 deploy your microservices using Kubernetes and adopt Istio, then explore centralized log management using the Elasticsearch, Fluentd, and Kibana (EFK) stack, and then monitor microservices using Prometheus and Grafana. By the end of this book, you'll be building scalable and robust microservices using Spring Boot and Spring Cloud.

Using a Service Mesh to Improve Observability and Management

In this chapter, you will be introduced to the concept of a service mesh and see how its capabilities can be used to handle challenges in a system landscape of microservices, in areas including security, policy enforcement, resilience, and traffic management. A service mesh can also be used to provide observability, the capability to visualize how traffic flows between microservices.

A service mesh overlaps partly with the capabilities of Spring Cloud and Kubernetes that we learned about earlier in this book. But most of the functionality in a service mesh complements Spring Cloud and Kubernetes, as we will see in this chapter.

The following topics will be covered in this chapter:

  • An introduction to the service mesh concept and Istio, a popular open source implementation
  • Deploying Istio in Kubernetes
  • Creating, observing, and securing a service mesh
  • Ensuring that a service mesh is resilient...
