Redis Cluster Management
Nextbrick provides redis cluster management services for organizations running or planning to deploy Redis Cluster for horizontal scalability and high availability. We handle cluster design, deployment, operations, and ongoing management for production environments.
Redis Cluster Management Services
Redis Cluster Design and Setup
We design Redis Cluster topologies based on your data size, throughput requirements, availability targets, and infrastructure constraints. Engagements cover shard count planning, hash slot distribution, replication factor selection, node sizing, network topology, and initial cluster bootstrap.
Redis Cluster Shard Management
As data volumes grow, Redis Cluster requires shard rebalancing. We manage CLUSTER REBALANCE operations, slot migration, and node addition/removal with zero-downtime procedures and rollback capability.
Redis Cluster Failover Configuration
Redis Cluster failover relies on cluster-node-timeout, cluster-require-full-coverage, and replica configuration. We validate these settings match your RTO requirements, test automatic failover behavior, and configure manual failover procedures for controlled maintenance windows.
Redis Cluster Monitoring
We configure cluster-specific monitoring covering: CLUSTER INFO state, slot coverage, node health, replication lag per shard, cross-shard operation patterns, and node memory/CPU utilization. Alerts integrate with PagerDuty, OpsGenie, and Slack.
Redis Cluster Troubleshooting
Cluster issues including CLUSTERDOWN state, slot migration stalls, split-brain scenarios, and ASK/MOVED redirect storms require specialist Redis Cluster knowledge. Nextbrick engineers respond to Redis Cluster incidents with structured diagnosis and resolution procedures.
Redis Cluster vs Redis Sentinel: When to Use Each
| Factor | Redis Cluster | Redis Sentinel |
|---|---|---|
| Primary purpose | Horizontal scalability + HA | High availability only |
| Data sharding | Yes, automatic slot-based | No, single dataset |
| Max dataset size | Limited only by cluster nodes | Single node memory |
| Multi-key operations | Limited (same hash slot only) | Full support |
| Client complexity | Cluster-aware client required | Standard client + Sentinel endpoint |
| Typical use case | Very large datasets, write scaling | HA for datasets fitting one node |
