Pay-per-Use Billing

Scenarios

Pay-per-use billing is ideal for uninterruptible applications or services with temporary, bursty, or unpredictable traffic.

Billing Items

Pay-per-use billing items for KVS are as follows:

Billing Cycle

Resource use in KVS is billed on an hourly basis. There are no charges for creating stores or creating, listing, or querying tables. You are billed based on the standard storage and write and read request units in each billing cycle. There are no minimum charges.

A duration of less than an hour is billed as a full hour. For example, assume you store data in KVS at a certain time between 10:00:00 and 11:00:00 on a day, you are billed for the whole hour of this billing cycle for storage.

Billing Formulas

Storage price = Used capacity (GB-hour) × List unit price

Request price = Request units × List unit price

KVS charges one WRU for 1 KB of KV items and one RRU for 4 KB of KV items. Table 2 shows how to convert the size of KV items into WRUs or RRUs.

In an API call, a standard write of less than 1 KB is billed as 1 KB, and a standard read of less than 4 KB is billed as 4 KB.

Billing Examples

The estimated prices in the following example are only for reference.

Assume that from 8:00:00 to 9:00:00 on a certain day, your table occupied 10 GB of storage and processed 1 million RRUs. From 9:00:00 to 10:00:00 on the same day, it occupied 10.1 GB and processed 2 million WRUs. The billing details for the cycle from 8:00:00 to 10:00:00 are as follows:

The table usage from 8:00:00 to 10:00:00 costed $3.673418061 USD.

Impact of Arrears

Figure 1 shows the statuses of pay-per-use KVS resources in different periods. The first period your resources in KVS enter is a validity period, when you can normally use them. If your account goes into arrears, your resources enter a grace period and if no payments are made within the specific time, they enter a retention period.

Impact of Arrears

KVS bills pay-per-use resources in each cycle based on the billing items. If bills are not paid when the usage of your expenditure quota reaches or exceeds 100%, your pay-per-use resources enter a grace period.

If bills are not paid during the grace period, your pay-per-use resources enter a retention period and get frozen, meaning you cannot do any operations on them.

If bills are not paid during the retention period, your pay-per-use resources will be deleted, and data cannot be restored.
