In one line
Node-hours if you size the cluster yourself. Serverless swaps that for GB-hours of stored data plus ECPUs.
What gets missed
Serverless meters a storage floor on every cache even when it holds almost nothing: 1 GB for Redis OSS and Memcached, 100 MB for Valkey. On node clusters, cross-AZ traffic to the cache bills at EC2 rates.
