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.

Delineating the containerization paradigm


Containers have emerged as the efficient runtime and resource for cloud applications (both cloud-enabled and native). Containers are comparatively lightweight, and hence hundreds of containers can be made to run on a physical or a virtual machine. There are other technical benefits such as horizontal scalability and portability. Containers almost guarantee the performance of physical machines. Near-time scalability is seeing the reality with the faster maturity and stability of the enigmatic containerization paradigm.

The ecosystem of containerization movement is growing rapidly, and hence containers are being positioned as the perfect way forward to attain the originally envisaged benefits of cloudification.

Containers are being positioned as the most appropriate resource and runtime to host and execute scores of microservices and their instances. The container monitoring, measurement, and management requirements are being sped up with the availability...
