Redis Sentinel
Automatic failover with cross-region replicas
Deploy Redis clusters with Sentinel for automatic failover and HAProxy for master routing. Support for cross-region replicas enables faster reads and geo-distributed caching.
Redis Sentinel Automatic Failover
Redis Sentinel monitors your Redis instances and automatically handles failover when the master node fails.
- Automatic failover: Detects master failures and promotes a replica within seconds
- Quorum-based decisions: Multiple sentinel nodes vote on failover decisions
- Configuration updates: Automatically updates client configurations after failover
- Health monitoring: Continuous monitoring of master and replica health
HAProxy Master Routing
HAProxy automatically routes all traffic to the current master node, handling failover transparently.
- Always points to master: HAProxy configuration updates automatically when master changes
- Transparent failover: Applications don't need to handle master changes
- Health checks: Monitors Redis health and routes traffic accordingly
- Load balancing: Can distribute reads across replicas when configured
Cross-Region Replicas
Deploy Redis replicas in different geographical regions for faster reads and improved availability.
- Geo-distributed caching: Serve cache reads from the closest region
- Automatic replication: Replicas stay in sync with the master via replication
- Faster reads: Lower latency for applications in different regions
- Disaster recovery: Replicas can be promoted to master in case of region failure
Persistence Options
Configure Redis persistence based on your durability requirements.
- RDB snapshots: Periodic snapshots for point-in-time recovery
- AOF persistence: Append-only file for better durability guarantees
- Hybrid approach: Combine RDB and AOF for optimal performance and durability
- Configurable persistence: Tune persistence settings based on your workload
Visual Config Editor
Customize your Redis and Sentinel configuration without editing raw config files. Our visual config editor layers your customizations on top of battle-tested defaults.
- Pre-configured defaults: Start with production-ready settings tuned for performance
- Override anything: Add custom settings that merge with our defaults
- No config conflicts: Your changes apply cleanly without breaking core functionality
- Version controlled: Track configuration changes across deployments
