ElastiCache Pricing Calculator - Valkey, Redis & Memcached

This ElastiCache pricing calculator uses official AWS pricing data updated regularly from Amazon's public pricing API. It accounts for regional pricing differences, engine-specific rates, and Reserved Node discounts. For production budgets, verify final costs in the AWS Billing console since pricing occasionally changes.

Valkey is recommended for new deployments. Valkeyis an open-source, Redis-compatible cache engine that offers 20% lower costs for node-based deployments and 33% lower costs for serverless. It's API-compatible with Redis OSS, so migration is straightforward with no code changes required.

Node-based is best for predictable workloads where you know your memory and throughput needs. You get dedicated resources and can save up to 55% with Reserved Nodes. Serverless is ideal for variable workloads, development environments, or when you want automatic scaling without capacity management. Serverless charges based on data storage (GB-hours) and compute (ECPUs).

Use Memcachedfor simple key-value caching where you don't need advanced features like persistence, pub/sub, or complex data structures. Memcached is slightly faster for simple operations and supports multi-threaded architecture. Use Valkey or Redis when you need data structures (lists, sets, sorted sets), persistence, replication, or Lua scripting.

ElastiCache Reserved Nodes offer significant savings for long-term commitments. 1-year terms save approximately 30-40% compared to On-Demand pricing. 3-year termssave approximately 50-55%. Choose "No Upfront" for flexibility or "All Upfront" for maximum savings. Reserved Nodes are tied to a specific node type and region.

Yes, Graviton nodes are recommendedfor most workloads. Graviton-based nodes (r7g, m7g, t4g) offer up to 20% better price-performance than x86 equivalents. They're compatible with all ElastiCache engines and provide the same features. Only use x86 nodes if you have specific compatibility requirements.
