Pay-per-Use Billing

Updated on 2024-05-30 GMT+08:00

Pay-per-use billing means you pay nothing up front and are not tied into any contract or commitment. This section describes billing rules of pay-per-use GeminiDB Cassandra instances.

Application Scenarios

Pay-per-use billing is good for short-term, bursty, or unpredictable workloads that cannot tolerate any interruptions, such as applications for e-commerce flash sales, temporary testing, and scientific computing.

Billing Items

You are billed for the following items on a pay-per-use basis.

Table 1 Items billed on a pay-per-use basis

Billing Item

Description

Instance specifications

Instance specifications, including vCPUs and memory.

Storage space

Instance storage space, which is billed hourly on a pay-per-use basis.

Backup space

GeminiDB Cassandra provides backup storage up to 100% of your provisioned database storage at no additional charge.

After the free backup space is used up, charges are applied based on the backup space pricing details. Pricing is listed on a per-hour basis, but bills are calculated based on the actual usage duration.

(Optional) Public network bandwidth

GeminiDB Cassandra instances are accessible from public networks, and you are billed for the generated public network traffic, but not for private network traffic.

If you want to purchase a 3-node (specifications of each node: 2 vCPUs | 8 GB) GeminiDB Cassandra instance with 500 GB of storage space. At the bottom of the instance buying page, price details (excluding the backup space fee) will be displayed.

Figure 1 Example price

The price includes:

  • Instance specifications (including vCPUs and memory)
  • Selected storage space
NOTE:

The backup space fee is not included. For details about the backup price, see Product Pricing Details.

Billed Usage Period

Pay-per-use GeminiDB Cassandra instance usage is calculated by the second and billed every hour. The billing starts when ECS instance is created and ends when the instance is deleted.

NOTE:

It takes a certain time to create an instance. The billing starts from the time when the instance is successfully created. You can view the two time points on the Basic Information page. You can view the time when the instance is created beside the Created field.

For example, if you purchased a pay-per-use GeminiDB Cassandra instance at 8:45:30 and deleted it at 8:55:30, you are billed for the 600 seconds from 8:45:30 to 8:55:30.

Billing Examples

Suppose you purchased a pay-per-use instance on April 18, 2023, 9:59:30, and deleted it on April 18, 2023, 10:45:46. Two usage periods will be billed:

  • Usage of 30 seconds from 9:59:30 to 10:00:00
  • Usage of 2,746 seconds from 10:00:00 to 10:45:46
    • The free backup space is used from 10:00:00 to 10:45:00.
    • Ten GB of billing backup space is used from 10:45:00 to 10:45:46 and the billed duration is 46 seconds.

The price displayed in the pricing details is per hour, so you need to divide it by 3,600 to obtain the price for each second and then multiply the per-second price by the total number of seconds. GeminiDB Cassandra instances are billed individually.

Table 2 Formulas for billing pay-per-use GeminiDB Cassandra resources

Resource

Formula

Unit Price

Compute resources (including vCPUs and nodes)

Unit price of instance specifications x Required duration

For details about the unit price, see Cluster CPU/Memory on Product Pricing Details

Storage space

Storage space unit price x Purchase duration

For details about the unit price, see Storage Space on Product Pricing Details.

Backup space

Backup space unit price x Required duration x (Backup space – Storage space) (GB)

NOTE:

The billed duration refers to the length of time the billed backup space was used for.

For details about the unit price, see Backup Storage Space on Product Pricing Details.

Public network traffic

Tiered billing by fixed bandwidth

  • 0 Mbit/s to 5 Mbit/s (included): billed at a fixed unit price per Mbit/s
  • Greater than 5 Mbit/s: billed at a different price per Mbit/s

For details, see Bandwidth Price on Product Pricing Details page or Product Pricing Details.

Figure 2 shows how the total price is calculated.

NOTICE:

Prices in the figure are just examples. Actual prices are subject to Product Pricing Details.

For pay-per-use billing, decimal numerals on the price calculator are rounded off and are accurate to two decimal places. If the fee is less than $0.01 USD (after rounding off), $0.01 USD will be displayed.

Figure 2 Total price for a pay-per-use GeminiDB Cassandra instance

Price Change After Specification Change

If you change the specifications of a pay-per-use GeminiDB Cassandra instance, the original order will become invalid and a new order will be placed. You will be billed based on the new specifications.

If you change instance specifications within a given hour, multiple records will be generated. Different records record the billing for different specifications.

For example, if you purchased a pay-per-use instance (2 vCPUs | 8 GB) at 9:00:00 and changed the instance specifications to 4 vCPUs | 16 GB at 9:30:00, the following items will be billed:

  • Specifications 2 vCPUs | 8 GB usage from 9:00:00 to 9:30:00
  • Specifications 4 vCPUs | 16 GB usage from 9:30:00 to 10:00:00

Impact of Arrears

Figure 3 shows the statuses a pay-per-use GeminiDB Cassandra instance can go through throughout its lifecycle. After a GeminiDB Cassandra instance is purchased, it enters the valid period and runs normally during this period. If your account goes into arrears, the instance enters a grace period and then a retention period.

Figure 3 Lifecycle of a pay-per-use GeminiDB Cassandra instance

Arrears Reminder

The system will bill you for pay-per-use resources after each billing cycle ends. If your account goes into arrears, we will notify you by email, SMS, or internal message.

Impacts of Arrears

When your account is in arrears due to automatic fee deduction for pay-per-use GeminiDB Cassandra instances, the account status turns to arrears. In arrears, the pay-per-use instance continues rendering service but the instance enters the grace period. You are still responsible for expenditures generated during the grace period. You can view the charges on the Billing Center > Overview page and pay any past due balance as needed.

If you do not bring your account balance current before the grace period expires, the GeminiDB Cassandra instance status turns to Frozen and it enters a retention period. You cannot perform any operations on a pay-per-use GeminiDB Cassandra instance in the Frozen status.

If you do not bring your account balance current before the retention period ends, your instance will be released, and data cannot be restored.

NOTE:
  • During the retention period, you cannot access or use your instance but the data stored in it can be retained. The retention period for Huawei Cloud International website is 15 days.
  • During the grace period, you can access and use only some resources of your instance. The grace period for Huawei Cloud International website is 15 days.
