Couchbase XDCR vs Dbvisit Standby MultiPlatform

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.

Dbvisit Standby MultiPlatform, also called StandbyMP, manages standby database creation, synchronization and activation for disaster recovery with Oracle, SQL Server and PostgreSQL. A shared control center brings configurations across the supported platforms together, and the product can be managed through a user interface or CLI/API. Recovery features include one-click graceful switchovers, automatic or guided failover, cascading standby support, reporting, real-time monitoring and smart notifications. Its unified CLI and API support remote control and integration with third-party tools or software suites. The Oracle SE trial includes the Zero Data Loss option, which Dbvisit describes as continuous redo streaming for sub-second RPO. StandbyMP can be installed in on-premises and cloud environments, but it requires an underlying operating system; AWS RDS and OCI Autonomous Databases are unsupported. It supports Linux and 64-bit Windows, subject to certified operating system and database combinations. Cross-platform replication is unsupported except for SQL Server. Licensing is separate by platform and counted per Oracle database, SQL Server instance or PostgreSQL cluster. The full trial lasts 10 days, with a possible extension to 20 days by contacting support. Pricing is available on request.
