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.

Consul Connect

Consul Connect is a Service Mesh solution offered by HashiCorp. It is also known as Consul Service Mesh. On the HashiCorp website, you will find that the terms Consul Connect and Consul Service Mesh are used interchangeably. It is built upon Consul, which is a service discovery solution and a key-value store. Consul is a very popular and long-established service discovery solution; it provides and manages service identities for every type of workload, which are then used by Service Mesh to manage traffic between Services in Kubernetes. It also supports using ACLs to implement zero-trust networking and provides granular control over traffic flow in the mesh.

Consul uses Envoy as its data plane and injects it into workload Pods as sidecars. The injection can be based on annotations as well as global configurations to automatically inject sidecar proxies into all workloads in specified namespaces. We will start by installing Consul Service Mesh on your workstation, followed...
