This book provides an understanding of modern service mesh providers for building applications without needing to build traffic management, telemetry, and security solutions. Advanced cloud-native polyglot application developers need to focus only the business logic. The service mesh takes care of the Operations from the DevOps using automation that does not require any changes in the applications. Thanks to Anjali and Vikram for providing hands-on examples to understand these new technologies in an easy to understand fashion.

The embracing of microservices by the world of business is critical as they enable significantly faster deployment of new services and quick adaption of existing services with continuous availability. Microservices platforms are going through rapid change and engineers must keep up to avoid skill obsolescence.

Capabilities such as observability and canary are key in churning applications rapidly while keeping a large microservice mesh continually available. The mesh of microservices spans businesses and their partners, where they collectively provide services to their customers, and often span multi-cloud. Common business services, such as security and single identity management have become global requirements, which has fundamentally changed the design and operation of platforms. The mesh assumes far more control as it replaces troubled microservices nodes quickly with alternatives to provide continual availability.

Keeping up with such rapid technology change at a hands-on level is a must. This book manages to cover the high-level concepts and then maps them to actual tasks that engineers need to perform to design, deploy, and operate these systems.

The concepts around cloud-native development continue to mature and real use cases grow in number across a variety of industries. However, cloud native approaches are only beginning to have significant widespread impact on mission critical systems, or what some might call systems of record. This is the next big step forward for cloud-native applications.

Mission critical applications demand high levels of availability, resiliency, security, and visibility that in turn place strong demands on the underlying supporting platform. While there are many solid advantages to the cloud-native approach, the fact is that there are new and more things to be managed, and many new situations will be encountered.

A service mesh becomes a consistent and simplified way of dealing with many of those things that accompany the notion of a cloud-native mission critical system. While there are other approaches, those that are consistent with Kubernetes and based on open source will have the most significant impact and be the most easily adopted.

Mastering Service Mesh is a good book to read for an in-depth understanding of the concept of service meshes, as well as to gain detailed insights into the various service mesh offerings available today. Concrete examples throughout the book and accompanying samples help bring these topics into focus and demonstrate the concepts in action. This book is a necessary addition to the library of all those who are involved in creating, evolving, and operating cloud-native production environments that support cloud-native applications.
