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.

Ballerina programming 


My first impression of Ballerina was that it was an amazing language that would vastly improve the world of SRE. It provides everything we need in the decentralized world: libraries, IDEs, compilers, builders, deployers, documentation, and tools. In Ballerina's first demo, the developers created a REST endpoint listening on a network port, implemented communication with Twitter on their API, and embedded a hello function with the same code file as the main() function of their services, and all in a maximum of 15 minutes. They continued to show more examples, including how to use a circuit breaker with Ballerina in a few very simple steps. 

Ballerina evolved from the Apache Synapse project in 2005. It was developed by WS02 architects in response to integration implementations using existing languages. It is a simple programming language and was released under the Apache License v.2.0

Its syntax and runtime address the hard problems of endpoint integration. It is a Turing...
