CreateInstance - Elastic Compute Service - Alibaba Cloud Documentation Center

Creates a subscription or pay-as-you-go Elastic Compute Service (ECS) instance.

Usage notes

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

Take note of the following items:

Billing:
- You must familiarize yourself with 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:
- You can use IoOptimized to specify whether to create an I/O optimized instance.
- Select an instance type. See Instance families or call the DescribeInstanceTypes operation to query the performance data of an instance type, or see Best practices for instance type selection to learn about how to select instance types.
- Query available resources. Call the DescribeAvailableResource operation to query available resources in a specific region or zone.

Note If the QuotaExceed.ElasticQuota error is returned when you call this operation, you have reached the maximum number of instances of the specified instance type that can be created within the specified region or the maximum number of vCPUs for all instance types in a zone. 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 new instance. The system disk of the new instance is a clone of the specified image.
- If you want to create instances with 512 MiB of memory, you cannot use Windows Server images except for Windows Server Semi-Annual Channel images.
- If you want to create instances with 4 GiB or more of memory, you cannot use 32-bit operating system images.
Network type:
- Each instance that resides in a virtual private cloud (VPC) must be connected to only a single vSwitch.
- If VSwitchId is specified, the security group specified by SecurityGroupId and the vSwitch specified by VSwitchId must belong to the same VPC.
- The value of PrivateIpAddress depends on that of VSwitchId. PrivateIpAddress cannot be separately specified. If both VSwitchId and PrivateIpAddress are specified, the IP address specified by PrivateIpAddress must be an idle IP address within the CIDR block of the specified vSwitch.
Public bandwidth:
- As of November 27, 2020, the maximum bandwidth value available for you to create ECS instances or to change ECS instance configurations is subject to throttling policies for your account. To increase the maximum bandwidth value, submit a ticket. The throttling policy imposes the following constraints: Within a single region, the total maximum bandwidth value of all instances that use the pay-by-traffic billing method for network usage cannot exceed 5 Gbit/s, and the total maximum bandwidth value of all 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 addresses are assigned to the instance. You can call the AllocatePublicIpAddress operation to manually assign public IP addresses to instances.
- Network usage 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 the fixed bandwidth value. A fixed bandwidth is a specified amount of public bandwidth allocated to an instance that uses the pay-by-bandwidth billing method for network usage.
- If InternetChargeType is set to PayByTraffic, InternetMaxBandwidthOut specifies the peak bandwidth value. A peak bandwidth is the maximum amount of public bandwidth that an instance can consume when it uses the pay-by-traffic billing method for network usage. Network usage costs are calculated based on the volume of network traffic.
Security group:
- If no security groups are available in the region where you want to create an instance, you must first call the CreateSecurityGroup operation to create a security group in the region.
- The maximum number of instances that a security group can contain varies based 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. You can allow communication between instances by allowing mutual access between their security groups. For more information, see AuthorizeSecurityGroup and AuthorizeSecurityGroupEgress.
Storage:
- The instance is assigned a system disk whose size is determined based on the specified image. The size of the system disk must be at least 20 GiB and greater than or equal to the image size. For more information about system disk categories, see the description of SystemDisk.Category.
- The system disk of an I/O optimized instance can only be an enhanced SSD (ESSD) (cloud_essd), a standard SSD (cloud_ssd), or an ultra disk (cloud_efficiency).
- The maximum size of a data disk varies based on the disk category. For more information, see the description of DataDisk.N.Size.
- 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.
  Note If the QuotaExceed.DiskCapacity error is returned when you call this operation, you have reached the maximum capacity of disks of the specified disk category that can be created within the specified zone. You can go to the ECS console or Quota Center to request a quota increase.
User data: If the instance type supports user data, you can use UserData to pass in user data. User data is encoded in Base64. We recommend that you do not pass in confidential information (such as passwords or private keys) in plaintext as user data. This is because the system does not encrypt UserData values when API requests are transmitted. If you must pass in confidential information, we recommend that you encrypt and encode the information in Base64 and then decode and decrypt the information in the same way within the instance.
Others: When you call API operations by using Alibaba Cloud CLI or SDKs, you must delete periods (.) from some request parameters before you use the parameters. 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.
