RunInstances - Elastic Compute Service - Alibaba Cloud Documentation Center

Creates pay-as-you-go or subscription Elastic Compute Service (ECS) instances. This operation provides a wide array of features and functions and helps simplify the procedure to create and manage ECS instances. When you call this operation, you can choose to create multiple ECS instances at a time, automatically start the instances, and assign public IP addresses to them. You can also use the features provided by the operation, such as configuring an automatic release time for instances, using a launch template, and configuring custom CPU options, to customize instance configurations for better management of instances.

Operation description

Before you call this operation, familiarize yourself with the billing rules and pricing of ECS resources.

This operation is an asynchronous operation. After a request to create ECS instances is sent, ECS instance IDs are returned but the creation and startup of the instances may be incomplete. You can call the DescribeInstanceStatus operation to query the status of the instances. When the status of an instance is Running in the DescribeInstanceStatus response, the instance is created and started.

Considerations

Make sure that the number of ECS instances you create or the number of vCPUs on ECS instances of all instance types you create does not exceed the corresponding quota. Go to the Quota Center to view the quotas.
Before you create ECS instances of the Virtual Private Cloud (VPC) type in a region, create a VPC in the region. For more information, see Create a VPC.

Precautions

You can call the RunInstances operation to create up to 100 ECS instances at a time. To create more than 100 ECS instances, we recommend that you initiate multiple requests in batches or concurrently.
If you set InternetMaxBandwidthOut to a value greater than 0, public IP addresses are automatically assigned to the ECS instances to be created.

Note For the limits on the sum of maximum public bandwidths of ECS instances that use the pay-by-bandwidth billing method for network usage per region per Alibaba Cloud account, see the Public bandwidth limits section of the "Limits" topic.

Suggestions

Test scenarios: Set DryRun to true to perform a dry run without performing the actual request.
Release of ECS instances: Use AutoReleaseTime to configure an automatic release time for ECS instances in the request to RunInstances or call the DeleteInstances operation to release the instances.
Management and search of ECS instances: Add tags to the ECS instances by specifying Tag.N.Key and Tag.N.Value and append incremental suffixes by specifying UniqueSuffix to the hostname specified by HostName and the instance name specified by InstanceName. For more information, see Batch configure sequential names or hostnames for multiple instances.
Launch template: A launch template contains the parameters required to create an ECS instance so that you do not have to specify the parameters every time you create ECS instances. You can call the CreateLaunchTemplate operation to create a launch template. Then, in the request to RunInstances, you can specify LaunchTemplateId and LaunchTemplateVersion to use the launch template.
Disabling of Hyper-Threading (HT): In memory-intensive scenarios, set CpuOptions.ThreadsPerCore to 1 to disable HT and increase the memory-to-vCPU ratio.
Enabling of Jumbo Frames: Set NetworkOptions.EnableJumboFrame to true to enable the Jumbo Frames feature when you create ECS instances. For more information, see MTUs .
