/**
*
* Use AppConfig, a capability of Amazon Web Services Systems Manager, to create, manage, and quickly deploy application
* configurations. AppConfig supports controlled deployments to applications of any size and includes built-in
* validation checks and monitoring. You can use AppConfig with applications hosted on Amazon EC2 instances, Lambda,
* containers, mobile applications, or IoT devices.
*
*
* To prevent errors when deploying application configurations, especially for production systems where a simple typo
* could cause an unexpected outage, AppConfig includes validators. A validator provides a syntactic or semantic check
* to ensure that the configuration you want to deploy works as intended. To validate your application configuration
* data, you provide a schema or an Amazon Web Services Lambda function that runs against the configuration. The
* configuration deployment or update can only proceed when the configuration data is valid.
*
*
* During a configuration deployment, AppConfig monitors the application to ensure that the deployment is successful. If
* the system encounters an error, AppConfig rolls back the change to minimize impact for your application users. You
* can configure a deployment strategy for each application or environment that includes deployment criteria, including
* velocity, bake time, and alarms to monitor. Similar to error monitoring, if a deployment triggers an alarm, AppConfig
* automatically rolls back to the previous version.
*
*
* AppConfig supports multiple use cases. Here are some examples:
*
*
* -
*
* Feature flags: Use AppConfig to turn on new features that require a timely deployment, such as a product
* launch or announcement.
*
*
* -
*
* Application tuning: Use AppConfig to carefully introduce changes to your application that can only be tested
* with production traffic.
*
*
* -
*
* Allow list: Use AppConfig to allow premium subscribers to access paid content.
*
*
* -
*
* Operational issues: Use AppConfig to reduce stress on your application when a dependency or other external
* factor impacts the system.
*
*
*
*
* This reference is intended to be used with the AppConfig User Guide.
