-- Retrieves information about an environment. An environment is a
-- deployment group of AppConfig applications, such as applications in a
-- @Production@ environment or in an @EU_Region@ environment. Each
-- configuration deployment targets an environment. You can enable one or
-- more Amazon CloudWatch alarms for an environment. If an alarm is
-- triggered during a deployment, AppConfig roles back the configuration.
