Network routing and endpoints
In Azure, basic networking setup is done automatically when you provision network components such as virtual networks and subnets. In many scenarios, the default setup can be enough, and you don’t need to incorporate a custom configuration. For everything else, Azure gives you the possibility to introduce custom routes, use Border Gateway Protocol (BGP), and leverage service and private endpoints for improved security. We’ll briefly characterize them in this section.
System routes
When a subnet is provisioned, Azure automatically assigns a set of default routes to that resource. Those default routes are called system routes and cannot be created manually or customized. You can, however, override them using custom routes. Before we dive deeper into that topic, let’s quickly describe a route.
The easiest way to describe a route in Azure is by imagining a book’s index. That part of a book contains specific words or topics...
