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

What are containers?


Containers are not revolutionary groundbreaking concepts. It has been in action for quite a while. However, the world is witnessing the reentry of containers, mainly due to the wide adoption of cloud computing. The shortcomings of traditional virtual machines in the cloud computing space has also accelerated the use of containers. Container providers, such as Docker, simplified container technologies to a great extent, which also helped the large adoption of container technologies in today's world. The recent popularity of DevOps and microservices also acted as catalysts for the rebirth of container technologies.

So, what are containers? Containers provide private spaces on top of the operating system. This technique is also called operating system virtualization. In this approach, the kernel of the operating system provides isolated virtual spaces. Each of these virtual spaces are called containers or virtual engines (VEs). Containers allow processes to run on an isolated...
