Chargeable resources

When you create an ECS instance, the following resources determine its price:

  • Instance types, images, and cloud disks: Their prices vary according to their billing methods, including Subscription and Pay-As-You-Go. For more information, see Billing method comparison.

    • Instance types: Including the number of vCPU cores and the size of memory.

    • Images:

      • Public images: Only Windows OS images are charged. Linux or Unix-like OS images are free of charge.
      • Marketplace images: The price is determined by their suppliers.
      • Shared images or custom images: If they are created by using marketplace images, the price is determined by the image provider.
    • Cloud disks: The disks created together with an ECS instance have the same billing method with the ECS instance. The separately created disks are billed according to Pay-As-You-Go billing method. For a Pay-As-You-Go cloud disk, after an ECS instance is created, you can convert its billing method from Pay-As-You-Go to Subscription or upgrade configurations of a Subscription instance  to convert its billing method, to synchronize its lifecycle with the instance.

  • Public network bandwidth: If a public IP address is assigned to your ECS instance when you create or upgrade it, you must pay for the public network bandwidth. For more information, see Billing of network bandwidth.

    VPC-Connected ECS instances can access Internet by binding an EIP address. For more information, see Billing of EIP.
  • Snapshot: Currently snapshots are free of charge.
