:Apply savings plans

Last Updated:Sep 09, 2022

If you run long-term online applications, we recommend that you use savings plans to offset the bills of elastic container instances. This topic describes how to use savings plans to offset the bills of long-term elastic container instances.

Purchase savings plans

A savings plan is a discount plan that allows you to receive pay-as-you-go billing discounts in exchange for a commitment to use a consistent amount of resources (measured in USD/hour) over a one-year or three-year period. After a savings plan takes effect, it can offset qualified pay-as-you-go bills at a special discount. The discount that you are entitled to when you apply a savings plan is affected by factors such as the type, subscription period, and payment type of the savings plan. Before you purchase a savings plan, carefully read the effective rules of savings plans and select an appropriate savings plan based on your business requirements. For more information, see Overview.

Item

General-purpose savings plan

ECS compute savings plan

ECS elastic savings plan

Deduction limit

None.

The savings plans can be used to offset the bills only of elastic container instances that are created by using specified Elastic Compute Service (ECS) instance types.

The savings plans offset bills based on the actual resource usage. Therefore, the savings plans can offset only elastic container instances that are created by using the specified number of vCPUs and memory size.

Hourly commitment

As you commit to consume a fixed sum per hour when you purchase the savings plan, the savings plan offsets resource bills even if no consumed resources match the savings plan.

You do not need to commit to consume a fixed sum per hour when you purchase an ECS elastic savings plan. The savings plan does not offset resource bills if no consumed resources match the savings plan. However, the amount of sum that you can consume per hour cannot exceed 1/120 of the total committed sum.

Payment method

The savings plans support three payment options: All Upfront, Partial Upfront, and No Upfront.

The savings plans support only All Upfront.

Subscription period

1 year and 3 years.

1 year.

Scenarios

The savings plans are suitable for business with stable resource usage, such as system upgrades or cluster deployment, where instances may be created and released from time to time but the overall usage is relatively stable.

The savings plans are suitable for business with periodic resource usage changes, such as livestreaming or food delivery services. Resource consumption bursts only in a specific period of time.

For more information, see Savings Plan in the ECS console. When you purchase a savings plan, you can adopt a plan recommended by the system or select a plan based on your consumption trends.

  • If you want to optimize the costs of existing elastic container instances, you can go to the Recommended page for system recommendations.

  • If you have no existing elastic container instances, you can calculate bills of an elastic container instance and then calculate the hourly commitment based on the discount. Then, you can go to the Savings Plan page to purchase savings plans.

For more information, see Purchase and apply savings plans.

View deduction information of a savings plan

After you purchase a savings plan, the system matches the savings plan with elastic container instances to offset bills. You do not need to manually match the resources. You can view the deduction information of the savings plan in the Billing Management console.
