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.

The future of containerization – unikernels and hardened security

Containerization is still evolving, but the number of organizations adopting containerization techniques has gone up in recent times. While many organizations are aggressively adopting Docker and other container technologies, the downside of these techniques is still in the size of the containers and security concerns.

Currently, Docker images are generally heavy. In an elastic automated environment, where containers are created and destroyed quite frequently, size is still an issue. A larger size indicates more code, and more code means that it is more prone to security vulnerabilities.

The future is definitely in small footprint containers. Docker is working on unikernels, lightweight kernels that can run Docker even on low-powered IoT devices. Unikernels are not full-fledged operating systems, but they provide the basic necessary libraries to support the deployed applications.

The security issues of containers are much discussed...
