Continental Clusters
A continental cluster is a group of clusters that use routed networks or common carrier networks
for data replication and cluster communication to support package failover between separate
clusters in different data centers. Continental clusters are often located in different cities or
different countries, and can span hundreds or even thousands of miles.
