AWS Elastic Disaster Recovery vs Dbvisit Standby MultiPlatform

AWS Elastic Disaster Recovery recovers on-premises and cloud applications on AWS to reduce downtime and data loss. Recovery instances can launch within minutes from the latest server state or an earlier point in time. Afterward, replicated data can return to the primary site for failback, and non-disruptive recovery and failback drills can run while replication continues. Sources include physical infrastructure, VMware vSphere, Microsoft Hyper-V, and other cloud providers. Supported workloads run on supported Windows and Linux versions, including Oracle, MySQL, SQL Server, and SAP. Recovery targets include EC2 instances in another Availability Zone or AWS Region. Point-in-time recovery can provide an operational copy from before a security incident. Replication uses TLS 1.2 in transit and can use Amazon EBS encryption at rest, with VPN, Direct Connect, or VPC peering for private connectivity. The service supports up to 300 servers in one staging account and up to 3,000 in one target account using multiple staging accounts. Pricing is $0.03 per month, billed $0.028 per source server per hour; additional AWS resource charges apply.

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.
