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.

Deploying Istio Service Mesh for Non-Kubernetes Workloads

Istio and Kubernetes are technologies that complement each other. Kubernetes solves the problem of managing distributed applications packaged as containers isolated from each other and deployed in a consistent environment with dedicated resources. Although Kubernetes solves container deployment, scheduling, and management, it doesn’t solve traffic management between containers. Istio complements Kubernetes by providing traffic management capabilities, adding observability, and enforcing a zero-trust security model.

Istio is like a sidecar to Kubernetes; having said that, Kubernetes is a fairly new technology that got mainstream adoption approximately around 2017. From 2017 onward, most enterprises have used Kubernetes when building microservices and other cloud-native applications, but there are still many applications that are not built on Kubernetes and/or not migrated to Kubernetes; such applications are traditionally...
