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.

Processing a bond request

When we receive a request for bond information, our message processor is much simpler than it was for our CDS. Once someone posts a message to the effect that they need bond info, we receive BondRequestMessage with the information we need filled in. From there, we calculate the remaining information, as shown here. Again, this is a black box by design, so we don't concern ourselves with the technicalities underlying how a bond; is a bond, we let our quant library do what it does best:

public bool ProcessBondsMessage(BondsRequestMessage msg)
{
Bonds b = new Bonds();
return b.testYield(this);
}
