Learn Microservices - ASP.NET Core and Docker

Be ready for coding away next week

About the Book

You're a developer who knows nothing to Microservices. Which is fine, except that you need to start coding your next Microservices-based application using ASP.NET Core and Docker.

Don't worry: I have you covered. I've been training hundreds of developers like you during 16 years, and converted my experience into this book. I know from experience teaching what takes more time to learn in Microservices, and will spend time only where appropriate.

Plus this book is packed with exercises which build up into a full project: you develop two interdependent Microservices, each exposing a CRUD JSON API. You publish them in a Docker repository and run them in Docker.

Read this book, and you can code your Microservices within a week. Or your money back.

About the Author

Arnaud Weil
Arnaud Weil

Arnaud Weil is a born developer: when he was a kid he was controlling his electric train using an Atari ST and some self-made electronics, then as a teenager created and distributed worldwide one of the first Web browsers for some of the first pocket computers, when the Web was just beginning. In fact, he loves coding.

Turning a passion into a career, Arnaud has been coding all kinds of applications from factory tools to smartphone applications to house control solutions. His status as a freelancer allows him to help his clients with many different projects.

But what Arnaud enjoys most is helping other developers: that's why he teaches, speaks, and writes books.
