Foreword

"Our industry does not respect tradition – it only respects innovation."   
                                                                                       - Satya Nadella

Those words from Satya ring true with microservice architectures. I believe that microservices are a crucial spark of innovation in web development. In an agile world, we need an agile framework in the cloud that is working for us, processing inpidual actors and services. With this new power, we can deploy a framework that scales, improve resiliency, greatly reduces latency, increases our control of security, and upgrade the system without downtime. Microservices becomes the optimal architecture in our new, cloud-based development environment, and it can result in major cost benefits. 

Gaurav Aroraa masterfully takes us on a journey to explore the history of microservices. He carefully and thoroughly tours the architectural design concepts that accompany the evolution of microservices, from when James Lewis first coined the term to our current tools and implementations. 

The book starts at a high level, with detailed diagrams and descriptions that explain the architectural scenarios, and it uncovers all the values that you’ll receive with a microservices design. At this point, you might ask whether the book is about microservices architecture or is a how-to guide to .NET development. Importantly, the book provides practical knowledge about translating our current applications into this bold new world of microservices. On that journey, it does not speed up. In other books, you move so fast that you can’t understand how or why it works (you can only follow the instructions). You might code and pick up a few tactics along the way, mostly copying and coding by autopilot. However, this book teaches each concept and step in the development process with the attention and focus that it deserves.

In this second edition, Gaurav has crafted the most comprehensive book on microservice development. I’m excited to see him expand on new options for building microservice architectures. Join Gaurav, as you learn about Azure Service Fabric, Service Bus, Message Queuing, and more! 

Personally, I have had the privilege to know Gaurav for a few years now. He’s a Visual Studio and Development MVP (Microsoft Most Valuable Professional) awardee and a leader in the Microsoft cloud development community. I’ve worked closely with him on his powerful contributions to TechNet Wiki. In Building Microservices for .NET Core, I see his dedication and passion shine through. This book needed to be written. I am excited when I find gems like this. Gaurav thoroughly covers every detail, every parameter, and every consideration in tackling this weighty concept of developing a microservices architecture. Read this book, skip ahead where you’re knowledgeable about the given information, and absorb the author’s knowledge; share the book with your business contacts. The development community needs to adopt a microservices approach, and this book is a powerful advocate on that journey.
