You can call this operation to create a subscription or pay-as-you-go ECS instance.

Description

Note You can call the DescribeAvailableResource operation to query available instance resources in a specific region or zone. If you want to create multiple instances at a time that automatically enter the Running state after they are created, we recommend that you call the RunInstances operation.

When you create an ECS instance, take note of the following items:

  • Billing method:
    • You must fully understand the ECS billing methods before you create an instance, because you may be charged for resources used by the instance. For more information, see Billing overview.
    • If you create a subscription instance (PrePaid), available coupons in your account are used by default.
  • Instance type:
Note If the QuotaExceed.ElasticQuota error is returned when you create an instance, the maximum number of instances of the specified instance type in the current region has been reached, or the maximum number of vCPUs for all instance types has been reached. You can go to the ECS console or Quota Center to request a quota increase.
  • Image:
    • The image determines the system disk configurations of the instance. The system disk of the new instance is a clone of the specified image.
    • If the instance memory size is 512 MiB, you cannot use Windows Server images except for Windows Server Semi-Annual Channel images.
    • If the instance memory size is 4 GiB or larger, you cannot use 32-bit OS images.
  • Network type:
    • Each VPC-type instance must be connected to only one VSwitch.
    • When you specify VSwitchId, make sure that the security group specified by SecurityGroupId and the VSwitch specified by VSwitchId belong to the same VPC.
    • PrivateIpAddress depends on VSwitchId and cannot be specified separately. If you specify both VSwitchId and PrivateIpAddress, the IP address specified by PrivateIpAddress must be available in the CIDR block of the specified VSwitch.
  • Public bandwidth:
    • As of November 27, 2020, the peak bandwidth available for you to create ECS instances or change the configurations of ECS instances is subject to throttling policies in your account. To increase the peak bandwidth, submit a ticket. The following throttling policies apply:
      • In a single region, the sum of actual peak bandwidths of all ECS instances that use the pay-by-traffic billing method for network usage cannot exceed 5 Gbit/s.
      • In a single region, the sum of actual peak bandwidths of all ECS instances that use the pay-by-bandwidth billing method for network usage cannot exceed 50 Gbit/s.
    • If you call the CreateInstance operation to create an instance, no public IP address is assigned to the instance. You can call the AllocatePublicIpAddress operation to allocate public IP addresses manually.
    • Bandwidth fees are determined based on the settings of InternetChargeType and InternetMaxBandwidthOut.
    • The InternetMaxBandwidthIn value is irrelevant to billing because inbound data traffic is free of charge.
    • If InternetChargeType is set to PayByBandwidth, InternetMaxBandwidthOut specifies a bandwidth value.
    • If InternetChargeType is set to PayByTraffic, InternetMaxBandwidthOut specifies a peak bandwidth value. Actual costs are calculated based on the network traffic.
  • Security group:
    • If no security group is available in the region where you want to create an instance, you must call the CreateSecurityGroup operation to create a security group in that region first.
    • The maximum number of instances that a security group can contain depends on the security group type. For more information, see the "Security group limits" section in Limits.
    • Instances in the same security group can communicate with each other over the internal network. By default, instances in different security groups cannot communicate with each other. However, you can allow communication between instances by authorizing mutual access between their security groups. For more information, see AuthorizeSecurityGroup and AuthorizeSecurityGroupEgress.
  • Storage:
    • The instance is assigned with a system disk whose capacity is based on the image you specified. The capacity of the system disk must be at least 20 GiB and greater than or equal to the size of the image. For more information about categories of system disks, see the description of the SystemDisk.Category parameter.
    • When the system disk of an instance is a basic disk (cloud), an ultra disk (cloud_efficiency), or a standard SSD (cloud_ssd), data disks of the instance cannot be local SSDs (ephemeral_ssd).
    • System disks of I/O optimized instances can be only ultra disks (cloud_efficiency) or standard SSDs (cloud_ssd).
    • The maximum capacity of data disks varies depending on their categories. For more information, see the description of the DataDisk.N.Size parameter.
    • A maximum of 16 data disks can be attached to each instance. The mount points of data disks are allocated by the system in alphabetical order from /dev/xvdb to /dev/xvdz.
    • When data disks of an instance are local SSDs (ephemeral_ssd), the system disk of the instance must also be a local SSD. Excluding the system disk, the total capacity of local SSDs attached to an instance cannot exceed 1 TiB.
    • Local SSDs (ephemeral_ssd) must be specified when you create instances and cannot be added after the instances are created.
  • User data: If the instance type supports user data, you can use the UserData parameter to pass in user data. For more information, see Prepare user data. User data is encoded in Base64. We recommend that you do not pass in confidential information such as passwords and private keys in plaintext. This is because the system does not encrypt UserData values when API requests are transferred. If you must pass in confidential information, we recommend that you encrypt and encode the user data in Base64, and then decode and decrypt it in the same way within the instance.
  • Others: When you call API operations by using Alibaba Cloud Command Line Interface (CLI) and SDKs, you must delete periods (.) from request parameters before you use them. For example, use SystemDiskCategory instead of SystemDisk.Category as a request parameter.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
