Redis hosting and managed Memcached, compared
Each provider is profiled from its own documentation, with the source recorded against every figure. The question this category actually turns on is whether the store is purely in-memory or durably persisted — that decides whether it can be a cache in front of something else or a system of record on its own.
Caching
| Provider | Entry paid plan | Max dataset size | Persistence |
|---|---|---|---|
| Amazon ElastiCache | On-demand example: cache.r7g.large at $0.1752/hour. Actual entry price depends on node size and engine chosen. | Up 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. | Durable 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. |
| MemCachier | Basic tier: starting around $14/month, with 100MB, 250MB or 500MB storage options. | 100GB is the largest cache size listed, at the top of the Business plan. Enterprise adds larger cache sizes without naming one. | None: cached data is kept in memory at all times, never written to disk, and MemCachier performs no backup of customer caches |
| Redis Cloud | Essentials: from $0.007/hour, $5/month total. 250 MB-100 GB RAM and SSD, single DB. | 30 MB on the free Redis Cloud Essentials plan; paid Essentials plans start at 250 MB and run to 12 GB, or to 100 GB on the Essentials plans with Redis Flex, per the plan tables on this page. Redis Cloud Pro is separate: the plan comparison lists 50 TB memory size. | AOF (every write on Redis Cloud Pro, every second on paid Essentials) or snapshots every 1, 6 or 12 hours; free Essentials plans support no persistence at all. |
| Upstash Redis | $0.20 per 100,000 commands on Pay as You Go, with up to 100 GB data. Fixed monthly plans are also offered. | Up to 100 GB on Pay as You Go. Fixed plans range from 250 MB to 500 GB; Enterprise supports up to 10 TB. | Durable — data stays persistent in the cloud provider's block storage for durability and high availability. |
Which to consider
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.
Teams that specifically want Memcached's simpler protocol rather than Redis's data structures, and prefer a flat monthly price over metered billing.
Teams that want Redis from the company that maintains it, with an on-demand hourly Essentials tier cheap enough to run a small production workload without committing to a fixed plan.
Serverless and edge apps with spiky or low-baseline traffic — per-command billing means an idle app costs close to nothing, and the free tier covers real prototyping.
