This topic describes the billing items of ECS and billing methods of ECS resources.
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.
|Computing resource (vCPUs and memory)||You are charged based on the instance type that you choose. The instance type determines the number of vCPUs and the size of memory that you can use.||
|Image||The image fees are determined based on the image type and your usage.||
|EBS device (cloud disk or local disk)||The disk fees are determined based on the disk capacity and duration of use.
Note Local disks must be created together with instances and cannot be purchased separately. Prices of local disks are included in those of the instances to which the local disks are attached.

|Public bandwidth||If you use a public IP address to access the Internet, you are charged only for the outbound public bandwidth.||
|Snapshot||The snapshot fees are determined based on the snapshot size and storage 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 overview.
|ECS instance||When you change the billing method of an ECS instance, the billing method of its computing
resources (vCPU and memory) and system disk is 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, the services provided by the instance may be affected. If you want to continue to use 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 lost permanently. For more information about renewal, see Renewal overview.
