Hello @Luis Bernardo ,
Welcome to Microsoft QnA.
To build on top of Andreas, and to answer your query, as per your diagram zone 1 will represent AZ1, zone 2 represents AZ2 and zone 3 will represent AZ3. To take advantage of the benefits of availability zones, you will need to deploy your resources across multiple availability zones within a region. This can be done manually, by creating resources in different availability zones, or automatically, using Azure's built-in high availability and disaster recovery features.
If you want to replicate your VMs to another availability zone within the same region, you can use Azure Site Recovery. This service allows you to replicate your VMs to a secondary location, where they can be automatically failed over in the event of an outage or disaster. To set up Site Recovery, you will need to create a recovery plan that specifies the source and target VMs, as well as the recovery options and settings.
Hope that clears your query!
