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.

Logging

Logging is a type of instrumentation made available by the system, its various components, or the infrastructure layer. In this section, we will first visit logging challenges and then discuss strategies to reach a solution for these challenges.

Logging challenges

We will first try to understand the problem with log management in microservices:

  • To log the information related to a system event and parameter as well as the infrastructure state, we will need to persist log files. In traditional .NET monoliths, log files are kept on the same machine where the application is deployed. In the case of microservices, they are hosted either on virtual machines or containers. But virtual machines and containers are both ephemeral...
