Hello,

I am new to Azure, pls don't get upset if it's a silly question.

For On Premise database server or Azure VM, there are ways to make them highly available but I couldn't find any high availability option for Azure VNet.

The question I asked myself, do we really need HA for VNet? VNet is, in a way, collection of IP Addresses, route table, Gateway, etc. As IP Addresses, route table, Gateway are created separately in Azure ENV and are just mapped to a VNet - May be I could select Standard IP Address instead of Basic and more expensive SKU for gateway to meet my HA needs. Let's say I have created a new route in my route table and if that route table is not available for whatever reason, there could be connection issues.

There seems to be no option either to clone a VNet using Azure Portal.

Please help me understand if HA is required for a VNet and how Azure ensure it's availability.

Appreciate your Insightful response. thank you !!

    Hi @anil kumar ,

    An Azure virtual network is a logical representation of your network in the cloud environment. Your answer to the question is right, the resources such as public IP and Gateway have their own high availability options that you can opt for.

    However to talk about disaster recovery and ensuring availability of virtual networks i believe the following document will be of help: https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-disaster-recovery-guidance

    Please feel free to reach out in case of any questions. Hope this helps.
