What is azure virtual network

Azure Virtual Network is the fundamental building block for the private networks in Azure. Virtual Network is similar to Traditional Network in the sense that the user operates in their own data center but brings with it additional benefits of Azure infrastructure such as Scale Availability and Isolation.

Steps involved in the creation of azure virtual network

The first step is to log into the Azure portal with the user’s credentials.

On the dropdown menu located on the left-hand side of the screen, there will be an option called ‘Virtual Network’ which must be clicked to begin the process. To create a brand new Virtual Network, there is an option called ‘Create Virtual Network’ located at the bottom of the screen.
