How to Update A Virtual Network

Welcome back everyone, today we will be taking a look on how to update a virtual Network. yes, a virtual Netwoik can be updated!

So imagine You're assisting an Azure Admin with specific resource tasks.

A new Linux VM is needed for an FTP server, while the current VM is underutilized.

To monitor network flow and usage, the admin requests a new subnet for the FTP server.

The existing subnet must remain unchanged for future VM deployments. So we need to create a new Subnet for our work.

** First we create a new subnet on an existing virtual network (vNet)**

• search and select virtual machine

• create subnet

• give name and add

You have successfully finished creating a subnet. Only SFTP traffic will be sent over this subnet. You must set up a network security group to limit which ports on the subnet are permitted in order to improve security

• select virtual Network

• give group name

Now we create an inbound security rule

• change name
  
  

Congratulations! You've set up rules to permit incoming FTP traffic and established a new network security group. The new network security group must now be linked to the ftpSubnet

• select the subnet we created earlier and save

• Well done. You appear to have finished the necessary steps to get the network ready for moving the existing Linux virtual machine to a new subnet that is intended to manage incoming FTP traffic.
