There are different considerations when deciding where to allocate resources with latency and cost being the two obvious ones, but compliance sometimes plays an important role as well. To make use of the services in this region, customers will use the Amazon Virtual Private Cloud (VPC) to organize their AWS resources.

In both cases, when using virtually-synchronous replication, the process will require certification from each node and local (by node) write; as such, the number of writes is NOT distributed across multiple nodes but duplicated. It will also allow us to redirect read/write traffic to the primary and read-only traffic to all secondaries.
