## Indicative from-price range

Indicative from-price range for self-hosting MySQL InnoDB Cluster on 3 servers: about $72 to $337 per month (USD), as of 2026-10-19, for the reference workload (Group replication members: 3; Logical dataset size (GB): 500; MySQL Router nodes: 2). From-price by provider, each the cheapest server in that provider's own shortlist: $72 on DigitalOcean (basic-2vcpu-4gb, 2 vCPU, 4 GB RAM, fra1); $192 on OVHcloud (rise-1, 6 vCPU, 32 GB RAM, eu-west); $199 on Hetzner (AX41, 6 vCPU, 64 GB RAM, eu-central); $413 on Amazon Web Services (i7i.large, 2 vCPU, 16 GB RAM, us-east-1); $528 on Google Cloud (c4a-standard-4-lssd, 4 vCPU, 16 GB RAM, us-central1); $1,278 on Servers.com (el-01, 16 vCPU, 192 GB RAM, eu-west); $1,524 on Microsoft Azure (L8s_v4, 8 vCPU, 64 GB RAM, eastus).

Reference workload:
- Group replication members: 3
- Logical dataset size (GB): 500
- MySQL Router nodes: 2

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

Configuration: Low end: 3 x basic-2vcpu-4gb (DigitalOcean, 2 vCPU, 4 GB RAM, about $24 per server per month). High end: 3 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 3, the smallest baseline topology (three-member-group-replication). 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. The reference workload leaves these required inputs without a default unset, so the ranking does not account for them: Write intensity profile.

MySQL is a relational database management system that stores structured data in tables and serves it over SQL; InnoDB Cluster is its native high-availability feature, combining Group Replication, the MySQL Shell AdminAPI, and MySQL Router to keep a set of instances synchronized with automatic failover.

## Baseline topologies

- three-member-group-replication: 3 nodes minimum; roles: mysql-member
- cluster-plus-router: 3 nodes minimum; roles: mysql-member, mysql-router

## What drives the cost

- Group replication members: Number of MySQL Group Replication members participating in the cluster.
- Logical dataset size (GB): Approximate logical dataset size before replica overhead and growth headroom.
- Write intensity profile: High-level description of write intensity and transactional behavior.

### What drives the cost of self-hosting MySQL InnoDB Cluster?

The sizing inputs the calculator uses for MySQL InnoDB Cluster are: Group replication members; Logical dataset size (GB); Write intensity profile. Cost also depends on the number of servers and the provider chosen.

### What is the minimum number of servers for MySQL InnoDB Cluster?

The smallest baseline topology in the calculator's profile for MySQL InnoDB Cluster is three-member-group-replication (3 servers). Other baseline topologies: cluster-plus-router (3 servers minimum). The reference range above is computed for 3 servers.
