AWS ElastiCache Support
AWS ElastiCache support, troubleshooting and optimization.
ElastiCache speeds up applications, but evictions, memory fragmentation and connection storms can turn it into a bottleneck.
Common ElastiCache problems we fix
The Amazon ElastiCache issues our engineers see most often, and how we resolve them.
ElastiCache Redis high memory and evictions
When memory fills, keys are evicted according to the policy. We review key sizes, TTLs and maxmemory policy, then scale the node type or shard the cluster.
ElastiCache high CPU or latency
Slow commands such as KEYS or large sorted-set operations block Redis. We find them with slow log and rewrite access patterns.
Cannot connect to ElastiCache
ElastiCache lives inside a VPC, so connectivity depends on subnets, security groups and in-transit encryption settings. We trace the path and fix client TLS configuration.
Redis failover and cluster mode
We set up replicas, Multi-AZ and cluster mode so a node failure does not cause an outage.
ElastiCache cost optimization
Over-sized nodes and idle clusters cost money. We right-size, use reserved nodes and consider Valkey pricing.
How We Help With ElastiCache
Senior AWS engineers who explain what they change and why.
What we do
- Caching strategy and TTL design
- Cluster sizing and failover
- Security and encryption setup
- Migration from self-managed Redis
How it works
- Tell us what is wrong or what you want to improve
- We review with read-only access first
- We fix, explain and document the change
- We hand off with monitoring so it stays fixed
Specialized ElastiCache support
Deep-dive help for specific ElastiCache tasks.
ElastiCache Redis memory and eviction troubleshootingFix ElastiCache Redis memory pressure, evictions and OOM command errors. TwinTix finds big keys, sets TTLs and eviction policy, and right-sizes nodes.
Fix ElastiCache cannot connect and timeout errorsFix ElastiCache connection timeouts and refused connections. TwinTix checks VPC, security groups, subnet groups, TLS, AUTH and cluster endpoints.
ElastiCache caching strategy and invalidation patternsDesign an ElastiCache caching strategy: cache-aside, write-through, TTL and invalidation patterns that avoid stale data and stampedes.
Migrate self-managed Redis to ElastiCacheMigrate self-managed Redis to ElastiCache with low downtime. TwinTix plans RDB seeding or online migration, cutover, validation and rollback.
Frequently Asked Questions
Redis or Memcached?
Redis supports persistence, replication and rich data types. Memcached is a simple multi-threaded cache. Most new workloads choose Redis or Valkey.
What is cache eviction?
When memory is full, the engine removes keys based on the configured policy. High evictions mean the cache is too small or keys lack proper TTLs.
Can you add caching to our app?
Yes, we identify what to cache, choose a pattern and implement invalidation safely.
