This topic describes the specifications and pricing of Apsara PolarDB, including billing methods, billing items, and the pricing of storage capacity, SQL Explorer, data backups, and compute nodes.
Billing methods
Apsara PolarDB clusters support the following billing methods:
- Subscription
If you choose the subscription billing method, you must pay in advance for the compute cluster (for example, a primary node and a read-only node) that you create. Storage resources are still billed based on the per-hour usage. The charge is deducted from your account balance on an hourly basis.
- Pay-as-you-go (pay by hour)
If you choose the pay-as-you-go billing method, you pay for the resources after you use them. Regardless of the compute clusters or storage space, you are billed by hour. The charge is deducted from your account balance on an hourly basis.
Billing items
| Billing items | Billing method |
|---|---|
| Compute cluster (a primary node and one or more read-only nodes) | Subscription or pay as you go (pay by hour). |
| SQL Explorer | After you enable SQL Explorer, the billing method is specified as Pay-as-you-go. For more information, see SQL Explorer. |
| Storage space | Pay by hour. |
| Data backup | This feature is available for free. You are only charged for the storage space of backup files. For more information, see Back up data. |
| Global Database Network (GDN) | GDN is free of charge. You are only charged for the compute nodes that use GDN. For more information, see GDN. |
Storage pricing
Pay-as-you-go
- The price for regions in mainland China: USD 0.00077/GB/hour.
- The price for China (Hong Kong) and other regions outside mainland China: USD 0.00085/GB/hour.
SQL Explorer pricing
You are billed based on the storage space consumed by audit logs.
- The price for regions in mainland China: USD 0.0013/GB/hour.
- The price for China (Hong Kong) and other regions outside mainland China: USD 0.0019/GB/hour.
Data backup pricing
The backup and restoration features of Apsara PolarBD are free of charge. Only storage fees are charged. Fees are calculated based on the storage consumed by backups (cluster and log data) and the retention period of these backups.
| Region | Level-1 backup | Level-2 backup | Log backup |
|---|---|---|---|
| Mainland China | USD 0.000464/GB/hour | USD 0.0000325/GB/hour | USD 0.0000325/GB/hour |
| China (Hong Kong) and regions outside China | USD 0.000650/GB/hour | USD 0.0000455/GB/hour | USD 0.0000455/GB/hour |
| Backup type | Free quota | Billing method |
|---|---|---|
| Level-1 backups | Database storage usage × 50%
You can view the storage space that you have used on the Basic Information page in the console. |
Storage fee per hour = (The total physical storage of level-1 backups - Free quota)
× Unit price per hour
For example, if the total physical storage of the level-1 backups is 700 GB and database storage usage is 1,000 GB, then the storage fee per hour is USD 0.0928. The fee is calculated based on the following formula: [700 GB - (1,000 GB × 50%)] × USD 0.000464 = USD 0.0928. |
| Level-2 backups | None | Storage fee per hour = The total physical storage of level-2 backups × Unit price
per hour
For example, if the total physical storage of level-2 backups is 1,000 GB, the storage fee per hour is USD 0.0325. The fee is calculated based on the following formula: 1,000 GB × USD 0.0000325 = USD 0.0325. |
| Log backup | 100GB | Storage fee per hour = (The total physical storage of log backups - 100GB) × Unit
price per hour
For example, if the total physical storage of log backups is 1,000 GB. The storage fee per hour is USD 0.02925. The fee is calculated based on the following formula: (1,000 GB - 100 GB) × USD 0.0000325 = USD 0.02925. |
Global Database Network (GDN)
GDN supports free cross-regional transmission and only charges you for Apsara PolarDB clusters. For more information about the billing items of Apsara PolarDB clusters, see Compute node pricing.
Compute node pricing
All nodes in Apsara PolarDB clusters are hosted on dedicated resources. The CPU, memory, storage, and resources allocated to a node are exclusive to this node. This improves the stability and reliability of the node. The following table lists all types of nodes that are available.
| Node type | CPU and memory | Storage capacity | Maximum number of connections | Internal network bandwidth | Maximum number of IOPS | I/O bandwidth |

- An Apsara PolarDB cluster with a 2-core CPU and 8-GB memory provides the basic specifications required in tests, trials, and other scenarios with light load. We recommend that you do not use this type of clusters in a load-heavy production environment. We recommend that you use an Apsara PolarDB cluster with an 8-core CPU and 32-GB memory or higher specifications.
- If you have higher requirements, you can submit a ticket and contact after-sales services to upgrade the maximum storage capacity to 100 TB.

- The preceding table lists the prices of a single node. An Apsara PolarDB cluster consists of a primary node and a read-only node by default.
- You can select a node type for the primary node when you create a cluster. The same type will be automatically applied to read-only nodes.
- The maximum number of IOPS is a theoretically calculated value.
- The maximum number of connections for a cluster depends on the specifications of nodes, and does not change with the number of nodes.
- If you require higher computing performance and larger storage space (for example, 100 TB), you can submit a ticket to contact after-sales services.
FAQ
- Q: What is the price if I want to add a read-only node?
A: For an Apsara PolarDB cluster, a read-only node is billed at the same price as the primary node. For more information, see Compute node pricing.
- Q: Is the maximum storage capacity doubled after I add a read-only node?
A: No, Apsara PolarDB clusters run in a compute-storage separated architecture. Read-only nodes are used for computing. Adding read-only nodes does not change the storage capacity of the cluster.
Storage resources are provisioned in a serverless architecture. Therefore, you do not need to specify the storage space when you create a cluster. The cluster automatically expands the storage as the data size increases. You are only billed for the storage space that you have used. The storage capacity varies with node types. If you want to expand the storage capacity, upgrade your clusters.
