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.

Getting ready

For a production environment, the recommended approach is to use a curated, validated, and tested Istio release, either by public cloud providers such as AWS, Google, IBM, and Azure or private cloud providers such as Red Hat OpenShift.

IBM maintains Helm charts for popular open source software and its own middleware. You can add the helm repository from https://github.com/IBM/charts to add IBM-curated Kubernetes packages.

However, in this chapter, we will only focus on the installation of a particular release direct from https://github.com/istio/istio.

It is also important to note that you could also use managed Kubernetes services provided by public cloud providers to deploy your cloud-native microservices-based applications. In such cases, a specific setup is required before installation, depending on the Kubernetes platform. The Kubernetes managed platforms are...
