      Free tier granting

      Every month in the first three months (including the month of activation)

      Every month in the first three months after the activation of Serverless Cloud Function (SCF) (including the month of activation), you are entitled to a free tier, which will be reset in the next calendar month. The free tier will be granted when you purchase a package through free trial or will be granted automatically by the system by default. A free tier includes one million event-triggered function invocations and one million HTTP-triggered function invocations, resource usage of 1,000,000 GB, and public network outbound traffic of 2 GB. You can also get a free tier by purchasing a Personal Advanced package through free trial, and the function concurrency quota will be doubled.
      Note
      Users who have used SCF for less than three months as of June 1, 2022 will still be granted a free tier for one month on June 1.
      Users who have used SCF for less than two months as of June 1, 2022 will be granted a free tier on June 1 and July 1 for the respective months.
      Users who have used SCF for less than one month as of June 1, 2022 will be granted a free tier on June 1, July 1, and August 1 for the respective months.

      Every month three months later after activation

      Three months later after activation of SCF, you will no longer be entitled to a free tier, and the system will grant a basic package tier (including 500,000 invocations of event-triggered functions, 500,000 invocations of HTTP-triggered functions, resource usage of 100,000 GB, and public network outbound traffic of 2 GB) every month and deduct 0.06 USD per day. If you have valid packages, the system will not deduct the basic package fees. If the function resource usage, number of invocations, and public network outbound traffic in the last calendar month are all 0, the basic package fees will not be charged in the current month.

      Reminders

      The free tier for every month in the first three months cannot be accumulated and will be reset at the beginning of the next month.
      Upon settlement, fees are deducted in the order of free tier/basic package tier > namespace-specific package > region-specific package > pay-as-you-go billing (applying vouchers) > pay-as-you-go billing. In other words, the free tier/basic package tier is used first, and fees for extra usage are deducted from valid packages. If no valid packages are available or the packages have been used up, fees are charged in the pay-as-you-go mode.
      The free tier of resource usage is not applicable to idle provisioned concurrency.
      The function invocations in a calendar month are counted on the first day of the next month. If the function resource usage, function invocations, and public network outbound traffic are all 0 in the last month, the basic package fees will not be charged in the current month. If any function usage is generated in the current month, 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.
