Database Proxy pricing update

Last Updated：2026-04-07 08:08:33 Updated

We are updating pricing for Database Proxy in OceanBase Cloud, effective February 1, 2026.

Exclusive tier updates

Database proxy clusters of the Exclusive tier will become billable on all cloud vendors. Existing Exclusive proxy clusters will switch to pay‑as‑you‑go billing on the effective date. Any Exclusive proxy clusters created after that date will be billed pay‑as‑you‑go by default.
Billing formula: Total service cost = (price per vCPU‑hour) × (vCPUs per node) × (number of nodes) × (hours used)
Proxy deployment modes: Exclusive tier will support three deployment modes (single-zone deployment, dual-zone active-active deployment, and dual-zone primary-standby deployment). The new deployment modes no longer support three-zone deployment.

Shared tier updates

General tier renamed to Shared tier: The free quota for the Shared tier across different cloud vendors is calculated as the combined vCPUs of all Shared proxy clusters within an OceanBase instance can be up to 1/4 of the total vCPUs of the OceanBase instance's full‑featured replica nodes. Existing General proxy clusters are not affected. However, if the total number of vCPUs of your existing General proxy clusters already exceeds the new free quota, any additional proxy clusters must use the Exclusive tier when creating new database proxy clusters.

Example: For a dual‑IDC 16 vCPU (1‑1) deployment, the Shared tier free quota for that OceanBase instance is 16 × 2 / 4 = 8 vCPUs. You could create one 4 vCPU dual‑node proxy cluster, or two 2 vCPU dual‑node proxy clusters, etc. The minimum size for a single proxy node is 0.25 vCPU. If the total number of vCPUs of all General proxy clusters already exceeds 8, new tenants or read‑only/read‑write split endpoints can only be backed by Exclusive proxy clusters.
Proxy deployment modes: Shared tier will support two deployment modes (single-zone deployment and dual-zone active-active deployment). The new deployment modes no longer support three-zone deployment.

Price table

Cloud vendor	Region	Unit	Price per vCPU‑hour (USD)
AWS	All regions (excluding São Paulo)	1 vCPU (1 vCPU, 2 GiB memory)	0.120
AWS	São Paulo	1 vCPU (1 vCPU, 2 GiB memory)	0.155
GCP	Singapore, Jakarta, Oregon, Tokyo, and Frankfurt	1 vCPU (1 vCPU, 2 GiB memory)	0.120

The prices above are for reference only. Actual prices may vary by region and time. Please refer to the prices shown on the order page.
