## Indicative from-price range

Indicative from-price range for self-hosting Redis Cluster on 1 server: about $24 to $112 per month (USD), as of 2026-10-19, for the reference workload (Primary shards: 3; Replicas per shard: 1; Memory working set (GB): 50). From-price by provider, each the cheapest server in that provider's own shortlist: $24 on DigitalOcean (basic-2vcpu-4gb, 2 vCPU, 4 GB RAM, fra1); $64 on OVHcloud (rise-1, 6 vCPU, 32 GB RAM, eu-west); $66 on Hetzner (AX41, 6 vCPU, 64 GB RAM, eu-central); $138 on Amazon Web Services (i7i.large, 2 vCPU, 16 GB RAM, us-east-1); $176 on Google Cloud (c4a-standard-4-lssd, 4 vCPU, 16 GB RAM, us-central1); $426 on Servers.com (el-01, 16 vCPU, 192 GB RAM, eu-west); $508 on Microsoft Azure (L8s_v4, 8 vCPU, 64 GB RAM, eastus).

Reference workload:
- Primary shards: 3
- Replicas per shard: 1
- Memory working set (GB): 50

Price snapshot: 2026-10-19. Currency: USD. FX snapshot: 2026-10-19.

Configuration: Low end: 1 x basic-2vcpu-4gb (DigitalOcean, 2 vCPU, 4 GB RAM, about $24 per server per month). High end: 1 x rise-m (OVHcloud, 12 vCPU, 64 GB RAM, about $112 per server per month).

Methodology: This range is generated automatically from public provider price lists. It has not been reviewed by a person, it is not a quote, and it may differ from the total the calculator chooses for your own workload with its AI step. Method: the calculator's offer shortlist for the reference workload (the same ranking it builds before the AI step, up to 12 offers across providers; 12 here) is priced at its monthly list price in USD. The low end is the cheapest of the per-provider from-prices below and the high end is the median server of the combined shortlist, each multiplied by 1, the smallest baseline topology (shard-primaries-and-replicas). The from-price for each provider applies the same method to that provider's own shortlist (the calculator's ranking restricted to that provider), so it is the cheapest server that ranking offers there, not a recommendation. Prices are taken from the price snapshot dated 2026-10-19; prices quoted in EUR are converted with the ECB reference rate dated 2026-10-19. Servers with fewer than 2 vCPU or less than 4 GB RAM are not priced. Only server rental list prices for the product's own servers are counted: dependencies, licences, support, traffic charges, taxes and setup fees are not included.

Redis is an in-memory data structure server that exposes strings, hashes, lists, sets, and streams as fast key-value operations, most commonly deployed as a cache, session store, or message broker. It supports optional on-disk persistence and a sharded clustering mode for horizontal scale-out and replica-based failover.

## Baseline topologies

- shard-primaries-and-replicas: 1 node minimum; roles: shard-primary, shard-replica
- three-shard-ha-baseline: 6 nodes minimum; roles: shard-primary, shard-replica

## What drives the cost

- Primary shards: Number of primary shard groups in the cluster.
- Replicas per shard: Number of replica nodes assigned to each primary shard. Use at least 1 for conservative HA.
- Memory working set (GB): Estimated hot data that should fit into memory.

## Frequently asked questions

### How much does it cost to self-host Redis Cluster?

Indicative from-price range for self-hosting Redis Cluster on 1 server: about $24 to $112 per month (USD), as of 2026-10-19, for the reference workload (Primary shards: 3; Replicas per shard: 1; Memory working set (GB): 50). From-price by provider, each the cheapest server in that provider's own shortlist: $24 on DigitalOcean (basic-2vcpu-4gb, 2 vCPU, 4 GB RAM, fra1); $64 on OVHcloud (rise-1, 6 vCPU, 32 GB RAM, eu-west); $66 on Hetzner (AX41, 6 vCPU, 64 GB RAM, eu-central); $138 on Amazon Web Services (i7i.large, 2 vCPU, 16 GB RAM, us-east-1); $176 on Google Cloud (c4a-standard-4-lssd, 4 vCPU, 16 GB RAM, us-central1); $426 on Servers.com (el-01, 16 vCPU, 192 GB RAM, eu-west); $508 on Microsoft Azure (L8s_v4, 8 vCPU, 64 GB RAM, eastus). This is an automatically generated indicative figure from public price lists (price snapshot 2026-10-19), not a quote.

### What drives the cost of self-hosting Redis Cluster?

The sizing inputs the calculator uses for Redis Cluster are: Primary shards; Replicas per shard; Memory working set (GB). Cost also depends on the number of servers and the provider chosen.

### What is the minimum number of servers for Redis Cluster?

The smallest baseline topology in the calculator's profile for Redis Cluster is shard-primaries-and-replicas (1 server). Other baseline topologies: three-shard-ha-baseline (6 servers minimum). The reference range above is computed for 1 server.
