Sample Replication Strategy for an International Enterprise

In this scenario, an enterprise has two major data centers, one in London and the other in New York, separated by a WAN. The scenario assumes that the network is very busy during normal business hours.

In this scenario, the Number of hosts has been calculated to be eight. A fully connected, 4-way multi-master topology is deployed in each of the two data centers. These two topologies are also fully connected to each other. For ease of comprehension, not all replication agreements between the two data centers are shown in the following diagram.

The replication strategy for this scenario includes the following:

centers, with four masters in each data center.
