o determine the minimum number of Azure Bastion instances required for your scenario, where you have multiple virtual networks (VNets) spread across different regions and all are peered with each other, consider the following factors:

Region Consideration: Azure Bastion is a regional service, meaning it only needs to be deployed in each Azure region where you have resources that need to be accessed. It provides secure RDP and SSH access to all virtual machines within a region if they are network peered.
Peering Connectivity: Since all your VNets are peered with each other, a single Bastion host in each region can provide coverage for all VNets in that region. Azure Bastion uses the VNet peering connections to facilitate access to VMs across different VNets within the same region.
Given your setup:

US East: VNets 1, 2, 3
UK South: VNets 4, 5, 6
Asia East: VNets 7, 8, 9, 10
Minimum Number of Azure Bastion Instances:

One Bastion host in US East to cover VNets 1, 2, and 3.
One Bastion host in UK South to cover VNets 4, 5, and 6.
One Bastion host in Asia East to cover VNets 7, 8, 9, and 10.
Thus, you need a minimum of three Azure Bastion instances — one in each of these three regions — to ensure secure access to all VMs across your peered VNets in different regions.
