Hands-On Microservices with C# 8 and .NET Core 3 - Third Edition

By: Gaurav Aroraa, Ed Price

Overview of this book

<p>The microservice architectural style promotes the development of complex applications as a suite of small services based on specific business capabilities. With this book, you'll take a hands-on approach to build microservices and deploy them using ASP .NET Core and Microsoft Azure. </p><p>You'll start by understanding the concept of microservices and their fundamental characteristics. This microservices book will then introduce a real-world app built as a monolith, currently struggling under increased demand and complexity, and guide you in its transition to microservices using the latest features of C# 8 and .NET Core 3. You'll identify service boundaries, split the application into multiple microservices, and define service contracts. You'll also explore how to configure, deploy, and monitor microservices using Docker and Kubernetes, and implement autoscaling in a microservices architecture for enhanced productivity. Once you've got to grips with reactive microservices, you'll discover how keeping your code base simple enables you to focus on what's important rather than on messy asynchronous calls. Finally, you'll delve into various design patterns and best practices for creating enterprise-ready microservice applications. </p><p>By the end of this book, you'll be able to deconstruct a monolith successfully to create well-defined microservices.</p>

Monitoring our FlixOne application

In the previous section, we discussed monitoring telemetry, which provides us with data that we can analyze. It helps us monitor the health of the solution. In this section, we will add Application Insights to our FlixOne application.

For this code example, you'll need to have a valid Azure account. Refer to the previous Technical requirements section for a list of prerequisites.

To implement Application Insights for our application, we need a valid instrumentation key. To get this key, we need to set up the Application Insights resource. Follow these steps to create the resource:

  1. Log in to the Azure portal, using your credentials.
  2. Search for Application Insights, and then click Application Insights from the search results list:

  1. From the Application Insights screens, click Create Application Insights apps, as shown in...
