Hands-On Microservices with C#

By: Matt Cole

Overview of this book

C# is a powerful language when it comes to building applications and software architecture using rich libraries and tools such as .NET. This book will harness the strength of C# in developing microservices architectures and applications. This book shows developers how to develop an enterprise-grade, event-driven, asynchronous, message-based microservice framework using C#, .NET, and various open source tools. We will discuss how to send and receive messages, how to design many types of microservice that are truly usable in a corporate environment. We will also dissect each case and explain the code, best practices, pros and cons, and more. Through our journey, we will use many open source tools, and create file monitors, a machine learning microservice, a quantitative financial microservice that can handle bonds and credit default swaps, a deployment microservice to show you how to better manage your deployments, and memory, health status, and other microservices. By the end of this book, you will have a complete microservice ecosystem you can place into production or customize in no time.

Publishing a message

When we publish a message, there are various utilities that the RabbitMQ Control Panel provides to view exchanges, queues, and message traffic.

The following is a snapshot of our exchange immediately after a message is published:

And here is a screenshot after several deployment messages have been sent:

The next thing that I want to do is to walk you through what you will see in the RabbitMQ Control Panel, as the visuals make everything self-explanatory. The following is a screenshot showing that a consumer was connected to our exchange and received a message. This is denoted by the Publish (Out) message rate indicated in blue (for those viewing this book in black and white, this will be the triangular line shown at the 07:44:20 minute marker):

The following screenshot shows our message queue (Memory) after three deployment messages have been published...
