Hands-On Microservices with Spring Boot and Spring Cloud

By: Magnus Larsson

Overview of this book

Microservices architecture allows developers to build and maintain applications with ease, and enterprises are rapidly adopting it to build software using Spring Boot as their default framework. With this book, you’ll learn how to efficiently build and deploy microservices using Spring Boot. This microservices book will take you through tried and tested approaches to building distributed systems and implementing microservices architecture in your organization. Starting with a set of simple cooperating microservices developed using Spring Boot, you’ll learn how you can add functionalities such as persistence, make your microservices reactive, and describe their APIs using Swagger/OpenAPI. As you advance, you’ll understand how to add different services from Spring Cloud to your microservice system. The book also demonstrates how to deploy your microservices using Kubernetes and manage them with Istio for improved security and traffic management. Finally, you’ll explore centralized log management using the EFK stack and monitor microservices using Prometheus and Grafana. By the end of this book, you’ll be able to build microservices that are scalable and robust using Spring Boot and Spring Cloud.

Performing zero-downtime deployments

As already mentioned in Chapter 16, Deploying Our Microservices to Kubernetes (refer to the Performing a rolling upgrade section), being able to deploy an update without downtime becomes crucial with a growing number of autonomous microservices that are updated independently of one another.

In this section, we will learn about Istio's traffic management and routing capabilities and how they can be used to perform deployments of new versions of microservices without requiring any downtime. In Chapter 16, Deploying Our Microservices to Kubernetes (refer to the Performing a rolling upgrade section), we saw how Kubernetes can be used to perform a rolling upgrade without requiring any downtime. Using the Kubernetes rolling upgrade mechanism automates the entire process, but unfortunately provides no option to test the...
