    E-MapReduce:Pay-as-you-go

    Last Updated:Dec 09, 2024

    Pay-as-you-go is a billing method that allows you to use resources before you pay for the resources. If you use the pay-as-you-go billing method, you are charged based on the amount of resources that you use. Bills are generated and fees are deducted from your account balance at the end of each billing cycle. You can use resources on-demand and do not need to purchase a large number of resources in advance.

    Description

    Use scenarios

    The pay-as-you-go billing method is suitable for the following scenarios:

    • Resource usage fluctuates.

    • Temporary use of resources is required.

    Billing rules

    • Compute unit (CU) fees = Number of CUs × Unit price of CUs × Usage duration.

    • Enterprise SSD (ESSD) fees = ESSD capacity × Unit price of ESSD capacity × Usage duration.

    • Backend node (BE) fees = Unit price of BE specifications × Number of BEs × Usage duration.

    • Data storage fees = Storage resources × Unit price of storage resources × Usage duration.

    Billing cycle

    Bills are generated on an hourly basis at the top of every hour (UTC+8). A new billing cycle starts after the bills are settled.

    Billing examples

    StarRocks shared-nothing instances (standard specifications)

    The following table provides an example on how to calculate the total fees of a StarRocks shared-nothing instance. In this example, the instance resides in the China (Hangzhou) region and uses the standard specifications for BEs, the number of CUs used by each BE is 8, and the number of BEs is 3.

    Sample resource configurations:

    • FE computing resources: 24 CUs, storage resources: ESSD PL1 (recommended) with 300 GB

    • BE computing resources: 24 CUs, storage resources: ESSD PL1 (recommended) with 300 GB

    Billing component

    Fee (USD)

    • Total number of CUs: 48 (24 + 24)

    • Unit price of CUs: USD 0.050617 per CU per hour

    • Total ESSD capacity: 600 GB (300 + 300)

    • Disk type: ESSD PL1

    • Unit price of ESSD capacity: USD 0.00031900 per GB-hour

    • Usage duration: 1 hour

    Total fees = CU fees + ESSD fees = 2.429616 + 0.1914 = 2.621016

    • CU fees = Number of CUs × Unit price of CUs × Usage duration = (24 + 24) × 0.050617 × 1 = 2.429616

    • ESSD fees = ESSD capacity × Unit price of ESSD capacity × Usage duration = (300 + 300) × 0.00031900 × 1 = 0.1914

    StarRocks shared-nothing instances (high-performance storage specifications)

    The following table provides an example on how to calculate the total fees of a StarRocks shared-nothing instance. In this example, the instance resides in the China (Beijing) region and uses the high-performance storage specifications for BEs, the BE specifications are 16 cores, 64 GiB of memory, and a local SSD with 1,788 GiB, and the number of BEs is 3.

    Sample resource configurations:

    • FE computing resources: 24 CUs, storage resources: ESSD PL1 (recommended) with 300 GB

    • BE computing resources: 48 cores and 192 GiB of memory, storage resources: local SSDs with 5,364 GiB

    Billing component

    Fee (USD)

    • Number of CUs for FEs: 24

    • Unit price of CUs: USD 0.050617 per CU per hour

    • Total ESSD capacity of FEs: 300 GB

    • BE specifications: 16 cores, 64 GiB of memory, and a local SSD with 1,788 GiB

    • Unit price of BE specifications: USD 1.18 per hour

    • Number of BEs: 3

    • Disk type: ESSD PL1

    • Unit price of ESSD capacity: USD 0.00031900 per GB-hour

    • Usage duration: 1 hour

    Total fees = CU fees + ESSD fees + BE fees = 1.214808 + 0.0957 + 3.54 = 4.850508

    • CU fees = Number of CUs × Unit price of CUs × Usage duration = 24 × 0.050617 × 1 = 1.214808

    • ESSD fees = ESSD capacity × Unit price of ESSD capacity × Usage duration = 300 × 0.00031900 × 1 = 0.0957

    • BE fees = Unit price of BE specifications × Number of BEs × Usage duration = 1.18 × 3 × 1 = 3.54

    StarRocks shared-data instances

    The following table provides an example on how to calculate the total fees of a StarRocks shared-data instance. In this example, the instance resides in the China (Hangzhou) region and is of the standard edition, the number of CUs used by each compute node (CN) is 8, and the number of CNs is 3.

    Sample resource configurations:

    • FE computing resources: 24 CUs, storage resources: ESSD PL1 (recommended) with 300 GB

    • CN computing resources: 24 CUs, storage resources: ESSD PL1 (recommended) with 150 GB

    Billing component

    Fee (USD)

    • Total number of CUs: 48 (24 + 24)

    • Unit price of CUs: USD 0.050617 per CU per hour

    • Total ESSD capacity: 450 GB (300 + 150)

    • Disk type: ESSD PL1

    • Unit price of ESSD capacity: USD 0.00031900 per GB-hour

    • Unit price for data storage: USD 0.000036041667 per GB-hour

    • Usage duration: 1 hour

    Total fees = CU fees + ESSD fees = 2.429616 + 0.14355 = 2.573166

    • CU fees = Number of CUs × Unit price of CUs × Usage duration = (24 + 24) × 0.050617 × 1 = 2.429616

    • ESSD fees = ESSD capacity × Unit price of ESSD capacity × Usage duration = (300 + 150) × 0.00031900 × 1 = 0.14355

    Important

    The fees for data storage vary based on the actual usage.
