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.

Data analysis using data lakes


Similarly to the scenario of fragmented logs and monitoring, fragmented data is another challenge in the microservice architecture. Fragmented data poses challenges in data analytics. This data may be used for simple business event monitoring, data auditing, or even deriving business intelligence out of the data.

A data lake or data hub is an ideal solution to handling such scenarios. An event-sourced architecture pattern is generally used to share the state and state changes as events with an external data store. When there is a state change, microservices publish the state change as events. Interested parties may subscribe to these events and process them based on their requirements. A central event store may also subscribe to these events and store them in a big data store for further analysis.

One of the commonly followed architectures for such data handling is shown in the following diagram:

State change events generated from the microservice—in our case...
