XDCR use cases

XDCR use cases

Disaster Recovery. Disaster can strike your datacenter at any time – often with little or no warning. With active-active cross datacenter replication in Couchbase Server, applications can read and write to any geo-location ensuring availability of data 24x365 even if an entire datacenter goes down.

Bringing Data Closer to Users. Interactive web applications demand low latency response times to deliver an awesome application experience. The best way to reduce latency is to bring relevant data closer to the user. For example, in online advertising, sub-millisecond latency is needed to make optimized decisions about real-time ad placements. XDCR can be used to bring post-processed user profile data closer to the user for low latency data access.

Data Replication for Development and Test Needs. Developers and testers often need to simulate production-like environments for troubleshooting or to produce a more reliable test. By using cross datacenter replication, you can create test clusters that host subset of your production data so that you can test code changes without interrupting production processing or risking data loss.
