How the load balancer works in two diffrenrnt vnet?

Question

Hi,

We have two or multiple different region Vnets, and all are peering with each other. All VMs can communicate and ping each other. So let's suppose one region's vnet has some problems, and VMs in that region do not work. In that case, how will the load balancer balance the things and automatically move to another healthy region vnet? and configurations we have to perform?

Hi Khushboo,

Load balancer works for specific resources(Web server/application server) instead of whole virtual network.

Load balancer health probs define which instance is healthy and accepting resources: https://learn.microsoft.com/en-us/azure/load-balancer/load-balancer-custom-probe-overview

Now for Cross region load balancing you have Azure load balancer (Standard)

https://learn.microsoft.com/en-us/azure/load-balancer/cross-region-overview or you can go with Azure Front door/ Traffic manager to manage traffic between 2 regions .
