Learn how to use Istio to implement service mesh for complex and distributed workloads built using microservices architecture and deployed in Kubernetes.
Key Features
- Learn design, implementation, and troubleshooting of Istio in a clear and concise format.
- Apply the ideas and solutions learned to real-life work environments.
- 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. You'll 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. You'll 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.
What you will learn
- Overview of Service Mesh and what problems it solves
- Fundamentals of Istio, its architecture, installation, and deployment
- How to manage communication between microservices using Istio
- Different ways to secure the communications between microservices
- How to get insight into traffic flow in the service mesh
- Scale and extend Istio and deploy it in a production environment
- Apply the concepts learned to real-world scenarios
Who This Book Is For
The book is intended for DevOps engineers, SREs, Cloud and Software Developers, Sysadmins, and Architects who have been using microservices in Kubernetes-based environments and want to solve the application networking challenges during microservice communications. Intermediate knowledge of Kubernetes, programming languages like Golang or similar, DevOps, application networking, and security is required.
