Deployment Mode - Dual-IDC Deployment: Two nodes are deployed across two zones, with a third node deployed in a different zone solely for log synchronization. This node does not provide read/write services. Dual-IDC deployment offers the same availability as multi-IDC deployment but with significantly improved cost efficiency. The dual-IDC deployment option is supported in versions 4.1.0.0 and later.
- Multi-IDC Deployment: Primary and standby nodes are located in different zones, enabling disaster recovery across zones. This deployment comes at no additional cost and by default, all three zones are selected.
Zone - Dual-IDC Deployment: Select two zones.
- Multi-IDC Deployment: Select three zones.
