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

Chapter 15. Scaling Dockerized Microservices with Mesos and Marathon

In order to leverage full power of a cloud-like environment, the dockerized microservice instances should also be capable of scaling out and shrinking automatically, based on the traffic patterns. However, this could lead to another problem. Once there are many microservices, it is not easy to manually manage thousands of dockerized microservices. It is essential to have an infrastructure abstraction layer and a strong container orchestration platform to successfully manage internet-scale dockerized microservice deployments.

This chapter will explain the basic scaling approaches and the need and use of Mesos and Marathon as an infrastructure-orchestration layer to achieve optimized resource usage in a cloud-like environment when deploying microservices at scale. This chapter will also provide a step-by-step approach to setting up Mesos and Marathon in a cloud environment. Finally, this chapter will demonstrate how to manage...
