Enterprise applications consist of several layers, that is, the data access layer, business layer, service layer, and presentation layer. Each layer is connected in a way that can be easily pluggable without affecting the other layers. Almost all applications deployed on Azure provide basic monitoring, which covers CPU usage, disk read/write, data in/out bandwidth, and so on.

The Azure portal provides some monitoring tiles out-of-the-box, which we can add on the dashboard to give us an overview, at a glance, of our running applications, VMs, and so on. This service is known as Azure Monitor and Diagnostic service.

We can also read the monitoring information from the code running on Azure by using the Azure Management API. This API provides easy access to insights into our applications. It provides real-time analytics reports and identifies trends that can be helpful for our business.
