Cross-region directory service

A computer-implemented method comprising:

• establishing a cross-region virtual network peering connection between a first directory virtual network of a directory service in a first region of a provider network and a second directory virtual network of the directory service in a second region of the provider network, the directory service comprising domain services, the second directory virtual network associated with a pre-allocated classless inter-domain routing (CIDR) range, wherein each virtual network is logically isolated from other virtual networks, and wherein traffic routed via the cross-region virtual network peering connection between the first directory virtual network of the directory service in the first region of the provider network and the second directory virtual network of the directory service in the second region of the provider network uses private Internet Protocol (IP) addresses, and wherein a route table in the first region for the second region is updated using the CIDR range;
• replicating, by a cross-region replicator, data or metadata associated with the directory service from the first region to the second region using the cross-region virtual network peering connection;
• and
• orchestrating one or more updates to the directory service in the second region based at least on the data or metadata replicated to the second region.

A system comprising:

• a memory;
• and
• one or more electronic devices coupled to the memory to implement a cross-region replicator and a cross-region directory service in a multi-tenant provider network, the one or more electronic devices comprising a processor, the cross region directory service comprising domain services, the cross-region directory service including instructions that upon execution cause the cross-region directory service to:
• establish a cross-region virtual network peering connection between a first directory virtual network of the cross-region directory service in a first region of the provider network and a second directory virtual network of the cross-region directory service in a second region of the provider network, the second directory virtual network associated with a pre-allocated classless inter-domain routing (CIDR) range, wherein traffic routed via the cross-region virtual network peering connection between the first directory virtual network of the cross-region directory service in the first region of the provider network and the second directory virtual network of the cross-region directory service in the second region of the provider network uses private Internet Protocol (IP) addresses, and wherein a route table in the first region for the second region is updated using the CIDR range;
• replicate data or metadata associated with the directory service from the first region to the second region using the cross-region replicator and the cross-region virtual network peering connection;
• and
• orchestrate one or more updates to the directory service in the second region based at least on the data or metadata replicated to the second region.
