HashiCorp Consul Cluster
Indicative from-price range
Indicative from-price range for self-hosting HashiCorp Consul Cluster on 6 servers: about $144 to $673 per month (USD), as of 2026-10-19, for the reference workload (Registered service instances: 500; Client agent node count: 20; KV store entries: 1000). From-price by provider, each the cheapest server in that provider's own shortlist: $144 on DigitalOcean (basic-2vcpu-4gb, 2 vCPU, 4 GB RAM, fra1); $294 on Google Cloud (e2-standard-2, 2 vCPU, 8 GB RAM, us-central1); $381 on Amazon Web Services (c9g.large, 2 vCPU, 4 GB RAM, us-east-1); $384 on OVHcloud (rise-1, 6 vCPU, 32 GB RAM, eu-west); $397 on Hetzner (AX41, 6 vCPU, 64 GB RAM, eu-central); $398 on Microsoft Azure (D2as_v7, 2 vCPU, 8 GB RAM, eastus); $1,573 on Servers.com (dl-01, 8 vCPU, 64 GB RAM, eu-west).
Reference workload

- KV store entries: 1000
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 6, the smallest baseline topology (three-server-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.

Consul is a networking tool from HashiCorp that provides service discovery, health checking, a distributed key-value store, and service mesh capabilities for distributed systems. It lets services find and securely communicate with one another across dynamic, multi-datacenter infrastructure.
Baseline topologies
| Topology | Minimum nodes | Roles |
|---|---|---|
| three-server-cluster | 6 | consul-server, consul-client |
| five-server-cluster | 8 | consul-server, consul-client |
What drives the cost
- Registered service instances
- Total number of registered service instances across the cluster. Drives server memory for catalog state and health check processing.
- Client agent node count
- Number of nodes running Consul client agents. Drives gossip protocol overhead and server heartbeat processing.
