Couchbase XDCR

Couchbase XDCR is a web-based service for replicating database changes between clusters. It supports change data capture and bidirectional synchronization, allowing changes to move in both directions. The deployment model is hybrid. Couchbase lists plans with hourly per-node billing, cluster minimums, and backup intervals. Basic is $0.15 a month, billed from $0.15/hr per node, with a one-node minimum and a 24-hour backup interval. Developer Pro is $0.35 a month, billed from $0.35/hr per node, with a one-node minimum, three nodes for multiple cluster availability zones, and backup intervals up to one hour. Enterprise is $0.49 a month, billed from $0.49/hr per node, with a three-node minimum and backup intervals up to one hour. Couchbase Enterprise is $0.66 a month, billed from $0.66/hr per node through cloud marketplaces, and includes Couchbase Server 8. A Free plan is described as one node and 8GB, although the pricing facts mark no free plan. Couchbase was founded in 2011 and is headquartered in San Jose.

It is intended for teams that need cluster-to-cluster database replication, captured changes, and two-way synchronization. The plan details help organizations match node counts and backup intervals to their deployment.
