Resource plan

Log Service provides the following resource plan.

Resource plan Description
Resource plan (Subscription Plan) You can purchase a resource plan to offset the fees of billable items. The billable items include used storage space, index traffic, read and write traffic, requests, data transformation, data shipping, alert notification messages (text messages), and alert notification calls. You can purchase one resource plan to offset the fees of all Log Service billable items.

Resource plan (Subscription Plan)

You can use a resource plan to offset the fees of billable items. Resource plans that have a higher quota and a longer validity period can be more cost effective. Log Service measures your resource usage on a daily basis. If you do not exceed the monthly quota of your resource plan, Log Service offsets the fees from your resource plan. If you exceed the monthly quota of your resource plan, you are charged for the excess resource usage based on the pay-as-you-go billing method.
Notice
  • Log Service provides yearly subscription options for resource plans. Resource plans for one year or longer provide savings based on the resource quota and duration. For more information about the prices for different resource plans, visit the buy page of Log Service. The prices of billable items that use the pay-as-you-go billing method remain unchanged. The savings are applied only when you purchase resource plans (Subscription Plan) for one year or longer.
  • You must pay all the fees of your resource plan when you purchase the resource plan. For example, if you purchase a 1-year and 100-CU/monthresource plan, you must pay all the fees on the day you purchase the resource plan.
Resource plans are measured in cost units (CUs). The price of each CU is USD 1.
The fee of each billable item is offset from a resource plan by using CUs. The number of CUs used to offset the fee of a billable item is consistent with the unit price of the billable item in the pay-as-you-go billing method. For example, the unit price of read and write traffic on Log Service is USD 0.045 per GB in the pay-as-you-go billing method. In a resource plan, 0.045 CUs are used to offset the fee of 1 GB of read and write traffic. The following table describes the billing details of a resource plan.
