Practical Site Reliability Engineering

By: Pethuru Raj Chelliah, Shreyash Naithani, Shailender Singh

Overview of this book

Site reliability engineering (SRE) is being touted as the most competent paradigm in establishing and ensuring next-generation high-quality software solutions. This book starts by introducing you to the SRE paradigm and covers the need for highly reliable IT platforms and infrastructures. As you make your way through the next set of chapters, you will learn to develop microservices using Spring Boot and make use of RESTful frameworks. You will also learn about GitHub for deployment, containerization, and Docker containers. Practical Site Reliability Engineering teaches you to set up and sustain containerized cloud environments, and also covers architectural and design patterns and reliability implementation techniques such as reactive programming, and languages such as Ballerina and Rust. In the concluding chapters, you will get well-versed with service mesh solutions such as Istio and Linkerd, and understand service resilience test practices, API gateways, and edge/fog computing. By the end of this book, you will have gained experience on working with SRE concepts and be able to deliver highly reliable apps and services.

Microservices using Spring Boot and the RESTful framework


The code bases of different companies often grow exponentially and increase in complexity. In a monolithic process, we have multiple independent development teams. These teams are not actually that independent at all; they simultaneously work on the same code bases and change the same sections of code. It is tough for new developers to contribute to the business, and the development process is slow. Because of this, we have seen a gradual shift toward microservices.

The following diagram shows the microservice container, the business logic image container, the data access layer container, and, in total, a working model of a microservice-based distributed model:

The Spring Framework is an enterprise Java framework that lets us write enterprise Java applications. Spring Boot is the way in which we can bootstrap, or quickly start, a simple Spring application. We can also build more complex applications quickly using Spring Boot. It allows...
