When you run ECS instances on a dedicated host (DDH), you are not charged for the vCPU or memory of those instances — the DDH covers those resources. You are still charged for the following ECS instance resources: images, disks, public bandwidth, and snapshots.
Billable items
① marks a billing method combination with a favorable price. For flexibility and cost-effectiveness, use pay-as-you-go ECS instances with a ① combination.
| Resource | Pricing basis | Billing methods | Switch billing method | References |
|---|---|---|---|---|
| Image | Image type and usage |
|
Not supported | |
| Disk | Disk capacity and usage duration |
|
Supported | |
| Snapshot | Snapshot size and storage duration |
|
Not supported | |
| Public bandwidth | Outbound traffic only (applies when using a public IP address) |
|
Supported |
Images can only be used with ECS instances. Reserved Windows instances include public images at no additional cost and can be applied to cover public image charges.
To switch the billing method for disks, see:
-
Change the billing method of an instance from subscription to pay-as-you-go
-
Change the billing method of an ECS instance from pay-as-you-go to subscription
To switch the billing method for public bandwidth, see Change the billing method of network usage.
Billing when instances are stopped
The following table shows ECS resource billing based on instance billing method and status, for instances running on a subscription dedicated host.
When creating a subscription ECS instance on a dedicated host, the instance expiration time cannot be later than that of the dedicated host.
| Billing method | Instance status | ECS resource billing |
|---|---|---|
| Subscription | Running | Charged for images, cloud disks, public bandwidth, and snapshots, each at its configured billing method. |
| Stopped | Charged for images, cloud disks, public bandwidth, and snapshots, each at its configured billing method. | |
| Pay-as-you-go | Running | Charged for images, cloud disks, public bandwidth, and snapshots, each at its configured billing method. |
| Stopped (Economical Mode disabled) | Charged for images, cloud disks, public bandwidth, and snapshots, each at its configured billing method. | |
| Stopped (Economical Mode enabled) | See below. |
Pay-as-you-go instances stopped with Economical Mode enabled
| Resource | Billing behavior |
|---|---|
| Image | Retained. Billing for paid images continues. |
| Disk | Retained. Billing continues. |
| Public bandwidth — public IP address | The public IP address is released. No further public bandwidth charges apply. |
| Public bandwidth — elastic IP address (EIP) | The EIP remains attached. EIP charges continue. |
| Snapshot | Retained. Snapshot fees continue. |
When a pay-as-you-go instance is stopped, its private IP address remains unchanged.
