Vector Retrieval Service for Milvus bills for Compute Units (CUs) and storage, with pricing that varies by region.
Billing
Vector Retrieval Service for Milvus charges consist of two components: Compute Units (CUs) and storage.
|
Billable item |
Description |
|
CU |
Compute resources for writes and queries, measured in Compute Units (CUs). 1 CU = 1 vCPU + 4 GiB memory. |
|
Storage |
No upfront provisioning required. Billed hourly based on actual usage, displayed on the instance's Details page. Important
Backup storage is also billed hourly based on usage. These charges are included in your total storage fee, not listed separately. |
For a subscription instance, the CU fee is a prepaid charge paid in full at purchase, so the CU portion does not generate a renewal charge before the subscription expires. However, storage is always billed hourly based on actual usage, regardless of how the CU portion is billed. As a result, a subscription instance still generates a pay-as-you-go storage bill every month, separately from the prepaid CU fee.
If you enable monthly auto-renewal for an instance, the CU portion generates a renewal charge every month. You can view and manage auto-renewal settings on the auto-renewal page of the Expenses and Costs console.
When pay-as-you-go billing is triggered
For a pay-as-you-go instance, CU fees are generated hourly based on the instance specifications as long as the instance is running, regardless of whether query or write requests are sent to the instance. Storage fees are also generated hourly based on actual storage usage. If you no longer need to use an instance, delete it at the earliest opportunity to avoid unnecessary fees for an idle running instance.
Billing after service shutdown due to overdue payment
After an instance is shut down due to overdue payment, no new pay-as-you-go fees are generated for the instance. When you settle the outstanding balance, the payment covers only the resource fees generated from the time the overdue payment occurred until the instance was actually shut down, and does not include the period after the shutdown. If you do not need to use the instance immediately, topping up your account in advance and keeping the instance running will still generate hourly fees. To reduce idle costs, settle the outstanding balance and start the instance shortly before you need to use it again.

Storage fee example
Assume 100 GB of storage in China (Hangzhou) at 0.00025 CNY/GB/hour. Using the formula Storage fee = Unit price × Data storage usage × Billing duration, storage fees are:
-
Fee for 1 hour: 0.025 CNY. Storage fee = (0.00025 CNY/GB/Hour) × 100 GB × 1 hour
-
Fee for 1 day: 0.6 CNY. Storage fee = 0.025 CNY × 24 hours
-
Fee for 1 month: 18 CNY. Storage fee = 0.6 CNY × 30 days
