What is cross-datacenter replication?
Cross-datacenter replication (XDR) lets data be reproduced – or replicated – across clusters that can be located in different clouds and various data centers.
The replication is used to guard against data-center failure. It’s also used to supply high-performance access to globally distributed applications that are mission critical. Cross-datacenter replication guarantees continuous service because if one of the data centers has a problem, there is backup data in another center.
Once replications are established, they continuously replicate until paused or deleted.
The telecommunications industry relies on cross-datacenter replication because data availability, consistency, resilience and low latency are critical.
