AWS::AppConfig::HostedConfigurationVersion

Create a new configuration in the AWS AppConfig hosted configuration store. Configurations must be 1 MB or smaller. The AWS AppConfig hosted configuration store provides the following benefits over other configuration store options.

  • You don't need to set up and configure other services such as Amazon Simple Storage Service (Amazon S3) or Parameter Store.

  • You don't need to configure AWS Identity and Access Management (IAM) permissions to use the configuration store.

  • You can store configurations in any content type.

  • There is no cost to use the store.

  • You can create a configuration and add it to the store when you create a configuration profile.
