01.Evaluation guide

Who it suits

Teams already on AWS that want engine choice (Valkey, Memcached or Redis OSS) under one billing model, or that specifically need Valkey's newer durable-persistence option.

Consider something else if…

AWS isn't the target cloud, or the free-tier eligibility window matters — it's restricted to accounts that signed up for AWS Free Tier before July 15, 2025.

Caching

4 criteria
Operations included per monthServerless bills every request in ECPUs (1 ECPU per KB); no free request allowance - the 750-hour Free Tier excludes Serverless, and later signups get $100 in credits instead. Scope: ElastiCache Serverless; node-based clusters are priced per node-hour instead.
Sources (1) →
  • Amazon ElastiCache Pricing ↗

    “You pay for ElastiCache Serverless requests in ElastiCache Processing Units (ECPUs), a unit that includes both vCPU time and data transferred. Reads and writes require 1 ECPU for each kilobyte (KB) of data transferred. [...] Exclusions include ElastiCache Serverless, AWS GovCloud (US) Regions, and China (Beijing) Region. [...] Either plan will offer you $100 in credits”

Max dataset size, entry planUp to 310 TiB of data in a single ElastiCache for Valkey cluster, or 982 TiB with data tiering. Cluster maximum for the service, not an entry-plan allowance; ElastiCache is sold per node or per usage.

Data persistenceDurable on Valkey 9.0+: data is stored persistently. Synchronous writes cost an 18% premium; asynchronous writes carry no additional cost. Redis OSS and Memcached engines are not documented as persistent here.

  • Amazon ElastiCache Pricing ↗

    “Durability is a feature available with Valkey 9.0, allowing you to use ElastiCache as a persistent data store with microsecond read latency. [...] ElastiCache offers two durability options: synchronous writes designed for zero data loss, and asynchronous writes for microsecond write latency. Pricing Beyond the standard node-hour pricing, there is no additional cost for asynchronous writes. Synchronous writes are priced at 18% on top of the standard node-hour price for node-based ElastiCache clusters.”
