Building Microservices with .NET Core 2.0 - Second Edition

By: Gaurav Aroraa

Overview of this book

The microservices architectural style promotes the development of complex applications as a suite of small services based on business capabilities. This book will help you identify the appropriate service boundaries within your business. We'll start by looking at what microservices are and their main characteristics. Moving forward, you will be introduced to real-life application scenarios; after assessing the current issues, we will begin the journey of transforming this application by splitting it into a suite of microservices using C# 7.0 with .NET Core 2.0. You will identify service boundaries, split the application into multiple microservices, and define service contracts. You will find out how to configure, deploy, and monitor microservices, and configure scaling to allow the application to quickly adapt to increased demand in the future. With an introduction to reactive microservices, you’ll strategically gain further value to keep your code base simple, focusing on what is more important rather than on messy asynchronous calls.

Instrumentation and telemetry

A monitoring solution is dependent upon instrumentation and telemetry. So it is natural that when we speak about monitoring microservices, we also discuss instrumentation and telemetry data. Logs are nothing more than an instrumentation mechanism.

Instrumentation

Now let's look at what instrumentation is. Instrumentation is one of the ways through which you can add diagnostic features to applications. It can be formally defined as follows:

''Most applications will include diagnostic features that generate custom monitoring and debugging information, especially when an error occurs. This is referred to as instrumentation and is usually implemented by adding event and error handling...
