RabbitMQ Cluster
Indicative from-price range
Indicative from-price range for self-hosting RabbitMQ Cluster on 3 servers: about $72 to $337 per month (USD), as of 2026-10-19, for the reference workload (Broker nodes: 3; Peak messages per second: 10000; Retained backlog (GB): 10). 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); $147 on Google Cloud (e2-standard-2, 2 vCPU, 8 GB RAM, us-central1); $190 on Amazon Web Services (c9g.large, 2 vCPU, 4 GB RAM, us-east-1); $192 on OVHcloud (rise-1, 6 vCPU, 32 GB RAM, eu-west); $199 on Microsoft Azure (D2as_v7, 2 vCPU, 8 GB RAM, eastus); $199 on Hetzner (AX41, 6 vCPU, 64 GB RAM, eu-central); $787 on Servers.com (dl-01, 8 vCPU, 64 GB RAM, eu-west).
Reference workload
- Broker nodes: 3
- Peak messages per second: 10000
- Retained backlog (GB): 10
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 (quorum-broker-cluster). 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: Queue durability profile.

Size RabbitMQ Cluster for your own workloadMarkdown versionFor AI agents (llms.txt)
RabbitMQ is a message broker that implements AMQP and other messaging protocols to route and queue messages between producers and consumers, supporting clustering and replicated queues for reliability.
Baseline topologies
| Topology | Minimum nodes | Roles |
|---|---|---|
| quorum-broker-cluster | 3 | broker |
| three-node-quorum-baseline | 3 | broker |
What drives the cost
- Broker nodes
- Number of RabbitMQ broker nodes in the cluster. Conservative quorum-queue guidance starts at 3.
- Peak messages per second
- Approximate peak publish-plus-consume rate handled by the cluster.
- Queue durability profile
- Queue durability and replication expectations.
