I understand we can mount persistent disks with containers created inside clusters. GCP offers us Regional persistent disks (standard and SSD) which is nothing but keeping a disk in two zones in one single region.
For example:
Disk-A is present in us-central1-a as well as a copy is maintained in us-central1-b. This way we can be sure that in case a zone goes down, we can shift our workload to another zone. This simply makes sure of High Availability in one region (e.g asia-south1) and multiple zones (e.g asia-south1-a and asia-south1-b) inside that region.
I am looking for a way to have multi-regional disks. I understand it is highly unlikely that the entire region will go down.
What are the ways to this? I have spent some time on Google but could not find anything.
