Hands-on examples using Istio along with Terraform, Gitops, Go, AWS, Kubernetes.

Book Description

Service mesh plays an important role in managing connectivity and operational efficiency of services in the cloud. Istio is one of the best service mesh architectures and Kubernetes-native solutions. While implementing Istio, challenges like security, multi-cluster deployments, load balancing, monitoring, API management, integrating VMs, etc. are common.

Bootstrapping Service Mesh Implementations with Istio will help you overcome them while deploying and securing applications at scale on platforms like Kubernetes.

This book will begin with the fundamentals of service mesh, why it is needed, and what applications use it. Youll learn about Istio service mesh installation, its architecture, its various components and their roles. You will be putting Istio to use in real-world applications and learn how to manage traffic, implement security and establish observability for microservices. Youll also learn to deploy Istio into production and decide which deployment options are best for your workloads. By the end, you will be able to perform zero trust and reliable communication between applications while getting optimal performance out of Istio. You will also know how to implement Istio and its best practices in your production environments to solve application networking challenges and build resilience in a distributed architecture.

Book Description

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 Istios 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.

Youll 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, youll 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. Youll 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, youll perform zero-trust security and reliable communication between distributed applications.

After reading this book, youll be equipped with the practical knowledge and skills needed to use and operate Istio effectively.
