Resource plan

Description

Resource plan

You can use this plan to offset the fees of all billable items in Simple Log Service.

Note

You receive a fixed resource quota each month for the duration of the plan. The quota resets at the end of each month, and any unused portion does not carry over.

Resource plan details

You can use a resource plan to offset the fees of all billable items in Simple Log Service. Resource plans with a higher quota and a longer validity period are more cost-effective. The system calculates your daily Simple Log Service usage and deducts it from the resource plan quota. During the validity period, you receive the same resource quota each month. If the monthly quota is exhausted, subsequent usage is billed on a pay-as-you-go basis.

Important
  • Both the pay-by-feature and pay-by-ingested-data billing modes are supported.

  • Simple Log Service offers yearly subscriptions for resource plans (one year or longer) with discounts based on the specifications. The exact discount is shown on the purchase page. The pay-as-you-go pricing remains unchanged. You can benefit from the discount policy only after you purchase a resource plan for one year or longer.

  • When you purchase a resource plan, Alibaba Cloud charges a one-time, upfront fee. For example, if you purchase a 1-year, 100 CU resource plan, you are charged the full annual fee on the day of purchase.

The unit for resource plan specifications is the cost unit (CU).

  • Resource plans support the pay-by-feature and pay-by-ingested-data billing modes.

  • The number of CUs from a resource plan consumed to offset a billable item is equivalent to the item's pay-as-you-go unit price. For example, the pay-as-you-go price for read/write traffic for Simple Log Service on the is USD 0.045/GB. Therefore, offsetting 1 GB of read/write traffic consumes 0.045 CUs.
