The biggest tech hub in India is in Bangalore, but both AWS and GCP chose Mumbai. Because of proximity to international data cables?
Datacenter staffing in the cloud is fairly easy; only about 6 or so are needed on-prem for HVAC and hands-on. The rest are remote. Many cloud datacenters are able to be located in extremely obscure locations because of this.
With AWS a region has more than one availability zone.
aws ec2 describe-availability-zones --region ap-south-1 for example shows two datacenters in mumbai.
Across physical site security, to power to network to just hard drive and system decommissioning, more than 6 staff.
I wonder if this is partly why AWS has done so well. I've used colo and hosted providers who do seem to have basically no one actually on site.
