Your company has an on-premises data center and an Azure subscription. The on-premises data center contains a Hardware Security Module (HSM).
Your network contains an Active Directory domain that is synchronized to an Azure Active Directory (Azure AD) tenant.
The company is developing an application named Application1. Application1 will be hosted in Azure by using 10 virtual machines that run Windows Server 2016.
Five virtual machines will be in the West Europe Azure region and five virtual machines will be in the East US Azure region. The virtual machines will store sensitive company information. All the virtual machines will use managed disks.
You need to recommend a solution to encrypt the virtual machine disks by using BitLocker Drive Encryption (BitLocker).
Solution: Deploy one Azure Key Vault to each region. Create two Azure AD service principals. Configure the virtual machines to use Azure Disk Encryption and specify a different service principal for the virtual machines in each region.
Does this meet the goal?
You would also have to import the security keys from the HSM into each Azure key vault.
