Billing Overview

Last updated: 2022-07-21 11:22:20

    Free Tier

    The free tier and billing mode of SCF will be adjusted as from 0:00, June 1, 2022 (Beijing time). By then, new users will get free tiers of more usage in the first three months after activation. As from the fourth month, users will no longer be entitled to free tiers, and the system will automatically grant a basic package tier (500,000 invocations, resource usage of 100,000 GBs, and public network outbound traffic of 2 GB) and deduct the basic package fees of 1.86 USD every month. For more information, see Free Tier.

    Note:

    • On the first day of every month, the platform counts the function invocations in the last calendar month. If the function resource usage, number of invocations, and public network outbound traffic in the last month are all 0, the basic package fees will not be charged in the current month. If any function usage is generated in the current month, the basic package fees will be charged next month.
    • HTTP-triggered function response traffic is not included in the free tier. For more information, see HTTP-Triggered Function Billing.

    Billable Items and Billing Modes

    Billable items

    SCF is billed by the following parts. Each part is billed according to its statistics and calculation method, and the fees are accurate to two decimal places in USD:

    • Resource usage fees: Resource usage is calculated in GBs by multiplying the configured function memory size by the function execution duration.
    • Invocation fees: Each function triggering and execution is calculated as an invocation.
    • Public network outbound traffic fees: The outbound traffic consumed when the function code accesses the public network is counted as the public network outbound traffic in GB.
    • Idle provisioned concurrency fees: The number of idle instances is calculated by subtracting the number of actually running concurrent instances from the number of started provisioned instances, and the idle resource usage is calculated in GBs by multiplying the number of idle instances by the configured memory size. For pricing details, see Provisioned Concurrency Price.
    • Basic package fees: After three months of activation of SCF, you will no longer be entitled to a free tier, and the system will grant a basic package tier and automatically deduct 1.86 USD (by deducting 0.06 USD per day) every month. If you have valid packages or remaining resource packs, the system will not deduct the basic package fees.
    Note:

    For HTTP-triggered functions using the default trigger, HTTP-triggered function response traffic will be additionally generated, which is not included in the free tier. For more information, see HTTP-Triggered Function Billing.
