Optimizing Your AWS ElastiCache Workload
When configured correctly, AWS ElastiCache can dramatically improve application performance — but many teams leave efficiency and cost savings on the table. Oversized nodes waste budget. Undersized clusters create bottlenecks. Default configurations often fail to match real-world workloads.
This practical guide walks you through a strategic approach to optimizing your ElastiCache deployment — improving performance, reducing costs, and ensuring long-term scalability.
Inside this guide, you’ll learn how to:
- Right-size nodes and choose the correct engine
- Use clustering (sharding) to scale memory and compute horizontally
- Optimize TTLs and eviction policies to prevent memory waste
- Improve Redis data structure efficiency and leverage pipelining
- Configure replicas effectively and tune read/write splits
- Reduce connection overhead with pooling and persistent connections
- Monitor key metrics like CPU utilization, evictions, and memory pressure
Whether you’re running production workloads at scale or fine-tuning an existing cache layer, this e-book provides actionable recommendations to turn ElastiCache into a cost-effective performance multiplier for your applications.

How Instacart Achieved 50% Better Performance with 70% Fewer Nodes
How Instacart migrated its ad-serving feature store from managed Valkey to Dragonfly, cutting cluster size ~70% and average and P99 latency 50% in weeks.
Dragonfly vs. Valkey 9.0 on AWS Graviton: An Honest Head-to-Head
Valkey 9.0 closed real ground on I/O. We reran the benchmarks on m7g and c7gn.metal to find out where, and where Dragonfly still wins.
SSD Data Tiering Is Generally Available
Dragonfly SSD Data Tiering is now GA. Scale beyond RAM limits on a single node — no resharding, no code changes. The only source-available Redis-compatible store with SSD tiering.
