Microservices with ASP.NET Core 10 for Beginners: A Practical Step-by-Step Guide to Building Distributed Web APIs with Docker, RabbitMQ, PostgreSQL, R

By Lucian Verne

Microservices can feel complicated-but learning them does not have to be.

If you have ever looked at words like Docker, RabbitMQ, PostgreSQL, Redis, API Gateway, or observability and felt overwhelmed, this book was written for you. Microservices with ASP.NET Core 10 for Beginners takes a friendly, step-by-step approach to help you understand modern backend development without confusion, pressure, or heavy theory.

You do not need to be an experienced software architect to begin. This practical guide gently introduces you to microservices, ASP.NET Core 10 Web APIs, distributed systems, and the real tools developers use to build scalable backend applications. Every chapter builds your confidence one small win at a time.

Instead of throwing you into complex code, this book explains what each part does, why it matters, and how it fits into a working project. You will create services, connect databases, run containers, use messaging, add caching, route requests through an API Gateway, secure endpoints, and observe your system as it runs.

Mistakes are part of the journey. A container may fail. A database connection may not work at first. A request may return an unexpected error. This book treats those moments as learning opportunities, helping you troubleshoot calmly and keep moving forward.
