Specify an AWS App Runner Automatic Scaling configuration by using the AWS::AppRunner::AutoScalingConfiguration resource in an AWS CloudFormation template.

The AWS::AppRunner::AutoScalingConfiguration resource is an AWS App Runner resource type that specifies an App Runner automatic scaling configuration.

App Runner requires this resource to set non-default auto scaling settings for instances used to process the web requests. You can share an auto scaling configuration across multiple services.

Create multiple revisions of a configuration by calling this action multiple times using the same AutoScalingConfigurationName . The call returns incremental AutoScalingConfigurationRevision values. When you create a service and configure an auto scaling configuration resource, the service uses the latest active revision of the auto scaling configuration by default. You can optionally configure the service to use a specific revision.

Configure a higher MinSize to increase the spread of your App Runner service over more Availability Zones in the AWS Region . The tradeoff is a higher minimal cost.

Configure a lower MaxSize to control your cost. The tradeoff is lower responsiveness during peak demand.

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.apprunner.*;
 CfnAutoScalingConfiguration cfnAutoScalingConfiguration = CfnAutoScalingConfiguration.Builder.create(this, "MyCfnAutoScalingConfiguration")
         .autoScalingConfigurationName("autoScalingConfigurationName")
         .maxConcurrency(123)
         .maxSize(123)
         .minSize(123)
         .tags(List.of(CfnTag.builder()
                 .key("key")
                 .value("value")
                 .build()))
         .build();
