Storage plan pricing
A storage plan can be used to offset the storage resource usage of Enterprise Edition clusters under your Alibaba Cloud account in the China (Hangzhou), China (Shanghai), China (Beijing), China (Shenzhen), Singapore, and US (Virginia) regions. The unit price of storage resources in a storage plan is as follows.
Billing method | Unit price |
Storage plan (subscription) | USD 0.0173/GB/month |
Storage plan offset factors
Storage plans have different offset factors for different regions. Therefore, the deductible capacity of a resource plan also varies based on the region of the instance. For example, for a 100 GB storage plan, the following table shows the storage resource capacity that can be offset per hour during its validity period.
Region | Zone | Offset factor | Effective capacity of a 100 GB plan |
China (Hangzhou), China (Shanghai), China (Beijing), China (Shenzhen) | Single zone | 1.00 | 100.00 GB |
Multi-zone | 1.34 | 74.63 GB (100 GB / 1.34) | |
Singapore | Single zone | 1.00 | 100.00 GB |
Multi-zone | 1.17 | 85.47 GB (100 GB / 1.17) | |
US (Virginia) | Single zone | 0.94 | 106.38 GB (100 GB / 0.94) |
Multi-zone | Not supported | — |
Examples
Deductible amount of a resource plan = Actual storage usage of the instance × Offset factor of the instance's region.
For example, assume you purchase a 100 GB storage plan and have a single-zone Enterprise instance in Singapore and a single-zone Enterprise instance in the US. The storage resource consumption of these instances can be offset by the same storage plan. If the Singapore instance uses 12 GB of storage resources for 1 hour, this offsets 12 GB × 1 H × 1.00 = 12 GB·h from the storage plan. If the US instance uses 10 GB of storage resources for 1 hour, this offsets 10 GB × 1 H × 0.94 = 9.4 GB·h from the storage plan. At the end of the hour, the total offset amount is 12 GB·h + 9.4 GB·h = 21.4 GB·h. Because the total offset amount is within the capacity of the purchased storage plan, no extra fees are incurred.
