Building Microservices with Spring

Overview of this book

Getting Started with Spring Microservices begins with an overview of the Spring Framework 5.0, its design patterns, and its guidelines that enable you to implement responsive microservices at scale. You will learn how to use GoF patterns in application design. You will understand the dependency injection pattern, which is the main principle behind the decoupling process of the Spring Framework and makes it easier to manage your code. Then, you will learn how to use proxy patterns in aspect-oriented programming and remoting. Moving on, you will understand the JDBC template patterns and their use in abstracting database access. After understanding the basics, you will move on to more advanced topics, such as reactive streams and concurrency. Written to the latest specifications of Spring that focuses on Reactive Programming, the Learning Path teaches you how to build modern, internet-scale Java applications in no time. Next, you will understand how Spring Boot is used to deploying serverless autonomous services by removing the need to have a heavyweight application server. You’ll also explore ways to deploy your microservices to Docker and managing them with Mesos. By the end of this Learning Path, you will have the clarity and confidence for implementing microservices using Spring Framework. This Learning Path includes content from the following Packt products: • Spring 5 Microservices by Rajesh R V • Spring 5 Design Patterns by Dinesh Rajput

Implementing Mesos and Marathon with DCOS


In Chapter 12, Scale Microservices with Spring Cloud Components, we discussed Eureka and Zuul for achieving load balancing. With container orchestration tools, load balancing and DNS services come out of the box and are much more simple to use. However, when developers need code-level control for load balancing and traffic routing, such as the business parameter based scaling scenarios mentioned earlier, Spring Cloud components may fit better.

Note

In order to understand the technologies better, we will use Mesos and Marathon directly in this chapter. However, in all practical scenarios, it is better to go with Mesosphere DCOS rather than playing with plain vanilla Mesos and Marathon.

DCOS offers a number of supporting components on and above plain Mesos and Marathon to manage enterprise-scale deployments.

Note

The DCOS architecture is well explained in the following link:https://dcos.io/docs/1.9/overview/architecture

Let's do a side-by-side comparison...
