Implementing Linkerd Service Mesh - Lee Kimiko

This capsule book is designed to provide DevOps teams, Networking Professionals, and Cloud Enthusiasts with the practical knowledge and skills required to set up and operate a robust service mesh with Linkerd. The book begins by demystifying the concept of service meshes, building a solid basis with an analysis of their evolution, key concepts, and the issues they face in modern cloud-native systems. It digs into Linkerd's architecture, explaining its components, features, and the seamless orchestration of microservices communication that it enables. 

As readers progress through the chapters, they are taken step by step through the installation and configuration of Linkerd. The book focuses on actual implementation, guiding readers through imperative and declarative methods to ensure a complete comprehension of the setup process.

The following chapters cover advanced subjects such as safeguarding interservice communications, configuring secure multi-cluster links, and implementing zero-trust authorization schemes in Kubernetes clusters. Topics includes how to organize services within Linkerd, manage error handling, retries, and timeouts, and implement effective multi-cluster communication and rollout strategies. A key chapter is about Rust programming, emphasizing its importance in developing efficient and secure micro proxies. Readers learn how to construct, integrate, and optimize these proxies to improve their service mesh deployment.

The book's conclusion prepares readers to work around progressive delivery, high availability, and integration with a variety of cloud settings and tools. This book serves as a complete guide, transforming its readers into skilled architects of Linkerd-based service mesh solutions, prepared to face the dynamic challenges of modern cloud-native infrastructures.
