Mastering Service Mesh

By: Anjali Khatri, Vikram Khatri

Overview of this book

Although microservices-based applications support DevOps and continuous delivery, they can also add to the complexity of testing and observability. The implementation of a service mesh architecture, however, allows you to secure, manage, and scale your microservices more efficiently. With the help of practical examples, this book demonstrates how to install, configure, and deploy an efficient service mesh for microservices in a Kubernetes environment. You'll get started with a hands-on introduction to the concepts of cloud-native application management and service mesh architecture, before learning how to build your own Kubernetes environment. While exploring later chapters, you'll get to grips with the three major service mesh providers: Istio, Linkerd, and Consul. You'll be able to identify their specific functionalities, from traffic management, security, and certificate authority through to sidecar injections and observability. By the end of this book, you will have developed the skills you need to effectively manage modern microservices-based applications.

An introduction to CNAs

With containerization becoming popular in 2015, the term "cloud-native" was used to describe container-based environments used to develop applications that have been built with services that can scale independently from each other and run on an infrastructure provided by a cloud provider. With DevOps processes getting automated, CNAs became part of Continuous Integration and Continuous Delivery (CI/CD) workflows. CNAs are related to infrastructure resources such as compute, memory, network, and storage, which are abstracted and self-provisioned as opposed to manually deployed resources.

One of the most popular cloud-native application development platforms is known as Red Hat OpenShift, a platform where we can focus on writing the business logic for the application. Containerization happens automatically, without having to write any code, while...
