Apache Cassandra Cluster
Indicative from-price range
Indicative from-price range for self-hosting Apache Cassandra Cluster on 3 servers: about $72 to $337 per month (USD), as of 2026-10-19, for the reference workload (Dataset size (GB): 500; Replication factor: 3; Peak write operations per second: 10000; Peak read operations per second: 10000). 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
- Dataset size (GB): 500
- Replication factor: 3
- Peak write operations per second: 10000
- Peak read operations per second: 10000
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 (ring-3-node). 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.

Apache Cassandra is a distributed, wide-column NoSQL database designed for high write throughput and continuous availability across multiple data centers with no single point of failure. It was originally built at Facebook and later donated to the Apache Software Foundation.
Baseline topologies
| Topology | Minimum nodes | Roles |
|---|---|---|
| ring-3-node | 3 | cassandra-node |
| ring-scaled | 6 | cassandra-node |
What drives the cost
- Dataset size (GB)
- Total dataset size before replication. Combined with replication_factor to determine raw storage requirements across the cluster.
- Replication factor
- Number of copies of each partition stored across the ring. Multiplies raw storage and write amplification proportionally.
- Peak write operations per second
- Peak sustained write operations per second. Primary driver for CPU, memory, and compaction throughput requirements.
