A savings plan is a discount privilege plan that provides savings over pay-as-you-go rates. You can apply savings plans to offset fees of pay-as-you-go elastic container instances, excluding preemptible elastic container instances. If you run online applications for an extended period of time, we recommend that you use savings plans to offset fees of elastic container instances. This topic describes how to use savings plans to offset fees of long-term elastic container instances.
Purchase savings plans
A savings plan is a discount privilege plan that provides discounts for pay-as-you-go instances in exchange for a commitment to use a consistent amount of resources within a one-year or three-year period. The amount of resources is measured in USD/hour. After a savings plan takes effect, the savings plan applies to eligible pay-as-you-go instances to reduce the costs of using the instances. The discount that you receive when you use 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 the savings plan and select a suitable savings plan based on your business requirements. For more information, see Overview.
