Bootstrapping Service Mesh Implementations with Istio

By: Anand Rai

Overview of this book

Istio is a game-changer in managing connectivity and operational efficiency of microservices, but implementing and using it in applications can be challenging. This book will help you overcome these challenges and gain insights into Istio's features and functionality layer by layer with the help of easy-to-follow examples. It will let you focus on implementing and deploying Istio on the cloud and in production environments instead of dealing with the complexity of demo apps.  You'll learn the installation, architecture, and components of Istio Service Mesh, perform multi-cluster installation, and integrate legacy workloads deployed on virtual machines. As you advance, you'll understand how to secure microservices from threats, perform multi-cluster deployments on Kubernetes, use load balancing, monitor application traffic, implement service discovery and management, and much more. You’ll also explore other Service Mesh technologies such as Linkerd, Consul, Kuma, and Gloo Mesh. In addition to observing and operating Istio using Kiali, Prometheus, Grafana and Jaeger, you'll perform zero-trust security and reliable communication between distributed applications. After reading this book, you'll be equipped with the practical knowledge and skills needed to use and operate Istio effectively.

Linkerd

Linkerd is a CNCF graduated project licensed under Apache v2. Buoyant (https://buoyant.io/) is the major contributor to Linkerd. Out of all Service Mesh technologies, Linkerd is probably one of the earliest, if not the oldest. It was initially made public in 2017 by Buoyant. It had initial success, but then it was criticized for being very resource hungry. The proxy used in Linkerd was written using the Scala and Java networking ecosystem, which uses the Java Virtual Machine (JVM) at runtime, causing significant resource consumption. In 2018, Buoyant released a new version of Linkerd called Conduit. Conduit was later renamed Linkerd v2. The Linkerd v2 data plane is made up of Linkerd2-proxy, which is written in Rust and has a small resource consumption footprint. Linkerd2- proxy is purpose built for proxying as a sidecar in Kubernetes Pods. While Linkerd2-proxy is written in Rust, the Linkerd control plane is developed in Golang.
