All three of the major cloud service providers have (or have announced) ‘have your cake and eat it’ versions of their services where data resides on premises whilst stuff is managed from a control plane in the cloud.

Late last year AWS launched Private DNS within Amazon VPC as part of their Route 53 service. This allows customers to create DNS entries that are only visible within a VPC (or group of VPCs). It’s also possible to have ‘split horizon’ DNS where servers inside a VPC get different answers to the same queries versus users […]
