Dedicated Cluster Cost

Dedicated clusters in Zilliz Cloud follows a pay-as-you-go model, where you are mainly charged for the compute resources consumed by your clusters. This ensures you only pay for what you actually use, without the need to over-provision resources in advance.

The total cost of a Dedicated cluster is the sum of the following components:

Vector database costs
Storage costs
Other costs (eg. Audit log costs and data transfer costs)

Vector database cost

Cost calculation

Vector Database Cost = Query CU Unit Price x Total Number of Query CU x Cluster Runtime

Query CU Unit Price: Determined by your cluster cloud region, type, and plan. For detailed rates, see Zilliz Cloud Pricing.
Total Number of Query CU: The total number of query node CUs in the cluster, factoring in replicas.
```
Total Number of Query CU = Number of Query CU × Replica Count
```
For example, a cluster with 2 query CUs and 2 replicas has a total of 4 CUs.
Cluster Runtime: The total time (in hours) your cluster is in a billable status:
- Billable statuses: Running, Modifying, etc.
- Non-billable statuses: Creating, Suspending, Resuming, Suspended, etc. During non-billable statuses, CU charges stop but storage charges still apply.

Example

Suppose your cluster configuration is as follows:

Plan: Dedicated (Enterprise)
Cloud Provider & Region: AWS us-east-1 (Virginia)
Cluster Type: Performance-optimized CU
Number of Query CU: 8 CU
Replica Count: 2
Cluster Runtime: 720 hours (1 month).

With the plan, cloud provider and region, and the cluster type information, you can find on the Pricing Page that the CU Unit Price is $0.248/hour.

According to the number of query CU and replica count, the total number of query CU is 8 CU x 2 Replica = 16 CU.

The total vector database cost of the example Dedicated cluster is $0.248 x 16 x 720 = $2856.96.

Storage cost

Storage costs are charged separately from CU costs and depend on:

Cluster cloud provider and region, type, and plan
Storage usage

For details, see Storage.

Other costs

Add-on features are billed separately. The following is the sources of add-on costs:

Audit Log Cost: Charged based on the CU usage for log data.
Data Transfer Cost: Charged for data egress over public internet, intra-region and cross-region data transfer.

For details, see Audit Log and Data Transfer.

FAQs

Will I be charged if I suspend my Dedicated cluster?

When your Dedicated cluster is suspended, vector database costs stop, but storage charges continue until you delete the cluster.
Will I be billed during cluster creation or suspension?

No vector database costs are charged while in Creating, Suspending, Resuming, or Suspended status. However, storage costs still apply.
