The example shows how to use Alibaba Cloud .NET SDK to call the CreateScalingGroup API to create an auto scaling group and how to specify the I/O optimized instance through the IoOptimized parameter.
Auto scaling is a management service that allows you to automatically adjust elastic computing resources according to your individual needs and policies.
Code example: Create an auto scaling group
Notice Make sure that you have activated the auto scaling service.

cscRequest.InstanceType = "ecs.t1.xsmall";
cscRequest.SecurityGroupId = "G0000000123456789";// You can obtain the SecurityGroupId through the DescribeSecurityGroups API of ECS
CreateScalingConfigurationResponse cscResponse = client.GetAcsResponse(cscRequest);
Console.WriteLine("ScalingConfigurationId: {0}", cscResponse.ScalingConfigurationId);

Code example: Specify the I/O optimized instance
CreateScalingConfigurationRequest cscRequest = new CreateScalingConfigurationRequest();
cscRequest.ScalingGroupId = scalingGroupId;
cscRequest.ImageId = "centos_7_04_64_20G_alibase_201701015.vhd";

cscRequest.IoOptimized = "optimized";
