Loads off intensive read workloads, to cache popular values.
Available engines follow:
| Memcached | Redis |
|---|---|
| Simple data structures (strings) | Advanced structure (many other) |
| No built-in replication | Multi-AZ replication |
| No backup support | Support backup & restores |
| Better with multi-threaded CPUs | Has Transactions, can treat multiple operations as one |
