The price of an ECS resource may vary with regions. For more information about ECS resource prices, see the Pricing tab on the Elastic Compute Service page.

|EBS device||The disk fees are determined based on the disk capacity and use duration.

ECS resources support the subscription and pay-as-you-go billing methods. You can combine different billing methods based on the ECS resource types to reduce costs. For more information, see Billing method overview.
|ECS instance||When you change the billing method of an ECS instance, the billing methods of its computing resources (vCPUs and memory) and system disk are also changed.
|Public bandwidth||For an instance that uses a public IP address, you can change its billing method for network usage by upgrading or downgrading the configurations of the instance.||Change the billing method for network usage|
When a subscription instance expires, services provided by the instance may be affected. If you want to continue using the instance, you must renew it within the specified period. Otherwise, instance resources such as vCPUs, memory, and disks are released and data stored in them is permanently lost. For more information about renewal, see Renewal overview.
