Creating environments for your application in AWS AppConfig
For each AWS AppConfig application, you define one or more environments. An environment is a
logical deployment group of AppConfig targets, such as applications in a Beta
or
Production
environment, AWS Lambda functions, or containers. You can also define
environments for application subcomponents, such as the Web
, Mobile
,
and Back-end
. You can configure Amazon CloudWatch alarms for each environment. The system
monitors alarms during a configuration deployment. If an alarm is triggered, the system rolls
back the configuration.
Before You Begin
If you want to enable AWS AppConfig to roll back a configuration in response to a CloudWatch alarm, then you must configure an AWS Identity and Access Management (IAM) role with permissions to enable AWS AppConfig to respond to CloudWatch alarms. You choose this role in the following procedure. For more information, see (Recommended) Configure permissions for automatic rollback.
