This topic describes how you are charged for Elastic Compute Service (ECS) resources after you deploy ECS instances on a dedicated host.

Billable item

For ECS instances that run on a dedicated host, you are not charged for the vCPUs, memory resources, and local SSDs of the instances. However, you are charged for the images, disks, public bandwidth, and snapshots of the ECS instances. The following table describes the billing details. ① indicates a combination of billing methods that has a favorable price.

Note We recommend that you create a pay-as-you-go ECS instance on a dedicated host and select a combination of billing methods that has a favorable price to balance flexibility and cost-effectiveness. ① in the following table identifies a combination of billing methods that has a favorable price.
Resource Description Billing method References
Image Image fees are determined based on the image type and your usage.
  • Subscription
  • Pay-as-you-go
  • Pay-as-you-go and reserved instances (public image)①
    Note Images can be used only along with ECS instances. Reserved Windows instances already include public images at no additional cost and can cover public image charges.
Disk Disk fees are determined based on the disk capacity and usage duration.
  • Subscription
  • Pay-as-you-go
  • Pay-as-you-go and savings plans①
Snapshot Snapshot fees are determined based on the snapshot size and storage duration.
  • Pay-as-you-go
  • Pay-as-you-go and storage capacity units (SCUs)①
Public bandwidth If you use a public IP address to access the Internet, you are charged only for the outbound public bandwidth.
  • Pay-by-bandwidth
  • Pay-by-traffic
  • Pay-by-bandwidth and savings plans①
  • Pay-by-traffic and data transfer plans①

Billing cycle

If a subscription dedicated host is running, the billing of the resources associated with the ECS instances on the dedicated host varies with the resource statuses.

Instance billing method Instance status Billing of additional ECS resources
Subscription Running You are charged for additional ECS resources such as images, disks, public bandwidth, and snapshots based on their individual billing methods.
Stopped You are charged for additional ECS resources such as images, disks, public bandwidth, and snapshots based on their individual billing methods.
Pay-as-you-go Running You are charged for additional ECS resources such as images, disks, public bandwidth, and snapshots based on their individual billing methods.
Stopped
  • If the economical mode is disabled, you are charged for additional ECS resources such as images, disks, public bandwidth, and snapshots based on their individual billing methods.
  • If the economical mode is enabled:
    • Image: Images are retained. The billing for paid images continues.
    • Disk: Disks are retained, and the billing continues.
    • Public bandwidth:
      • If ECS instances are assigned public IP addresses, the IP addresses are released and you are no longer charged for the public bandwidth.
      • If ECS instances are associated with elastic IP addresses (EIPs), the EIPs remain unchanged. You are charged for the EIPs until the instances are stopped.
      Note After ECS instances are stopped, the private IP addresses of the instances remain unchanged.
    • Snapshot: Snapshots are retained, and the billing continues.
