Overview of this book

The Spring Framework is an application framework and inversion of the control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions to build web applications on top of the Java EE platform. This book will help you implement the microservice architecture in Spring Framework, Spring Boot, and Spring Cloud. Written to the latest specifications of Spring, you'll be able to build modern, Internet-scale Java applications in no time. We would start off with the guidelines to implement responsive microservices at scale. We will then deep dive into Spring Boot, Spring Cloud, Docker, Mesos, and Marathon. Next you will understand how Spring Boot is used to deploy autonomous services, server-less by removing the need to have a heavy-weight application server. Later you will learn how to go further by deploying your microservices to Docker and manage it with Mesos. By the end of the book, you'll will gain more clarity on how to implement microservices using Spring Framework and use them in Internet-scale deployments through real-world examples.

Why cluster management is important

As microservices break applications into different micro-applications, many developers request more server nodes for deployment. In order to manage microservices properly, developers tend to deploy one microservice per VM, which further drives down the resource utilization. In many cases, this results in an overallocation of CPUs and memory.

In many deployments, the high-availability requirements of microservices force engineers to add more and more service instances for redundancy. In reality, though it provides the required high availability, this will result in underutilized server instances.

In general, microservice deployment requires more infrastructure compared to monolithic application deployments. Due to the increase in cost of the infrastructure, many organizations fail to see the value of microservices:

In order to address the issue stated before, we need a tool that is capable of the following:

  • Automating a number of activities, such as the allocation...
