AWS ElastiCache Redis Consulting and Support
Nextbrick provides AWS ElastiCache Redis consulting and support for organizations running Redis on Amazon ElastiCache. We cover architecture design, configuration optimization, performance tuning, failover setup, Global Datastore configuration, and migration to and from ElastiCache.
AWS ElastiCache Redis Services
ElastiCache Architecture Design
We design ElastiCache for Redis deployments including cluster mode enabled vs disabled selection, node type sizing, replication group topology, subnet group and VPC configuration, security group rules, and parameter group optimization for your workload.
ElastiCache Cluster Mode Configuration
Cluster mode enabled (CME) distributes data across up to 500 shards with automatic failover per shard. We configure shard count, replica count per shard, shard rebalancing, and application-side cluster-aware client configuration including Jedis, StackExchange.Redis, ioredis, and redis-py cluster mode.
ElastiCache Global Datastore
AWS Global Datastore enables cross-region active-passive replication for ElastiCache. We configure Global Datastore clusters, validate cross-region replication lag, plan regional failover procedures, and test promotion of secondary clusters to primary.
ElastiCache Performance Optimization
ElastiCache-specific performance work covers parameter group tuning (maxmemory-policy, tcp-keepalive, timeout, slowlog-log-slower-than), Enhanced I/O Multiplexing configuration for r6g/r7g nodes, and connection management for high-connection-count workloads.
Migration to AWS ElastiCache
We migrate self-managed Redis deployments to ElastiCache using RDB snapshot import for offline migrations and live replication using AWS DataSync or RIOT for online migrations with minimal downtime.
ElastiCache Monitoring and Alerting
We configure CloudWatch metrics and alarms for CacheMisses, CacheHits, Evictions, CurrConnections, ReplicationLag, EngineCPUUtilization, and DatabaseMemoryUsagePercentage with integration to PagerDuty and OpsGenie.
AWS ElastiCache Redis vs Self-Managed Redis
| Factor | AWS ElastiCache | Self-Managed Redis |
|---|---|---|
| Management overhead | Low — AWS handles patching, failover, backups | High — team manages all operations |
| Configuration flexibility | Limited to parameter groups | Full redis.conf control |
| Cost at scale | Higher per-node cost | Lower infrastructure cost, higher ops cost |
| Modules (Redis Stack) | Not supported on ElastiCache | Full module support |
| Compliance | AWS compliance certifications apply | Self-certified |
