title: Parameter store vs AppConfig
body: <p>When should I use Parameter store for saving configuration vs AppConfig? Forex: If I had to change the log level at run time, should that be stored in SSM or Appconfig?
  For some of the emails used in the project for testing, should those be stored in parameter store or app config?
  What are the pros/cons? I understand AppConfig is marketed as the place to store configurations of an application but what are the differences in these 2, specifically in the context of a serverless app with lambda functions.</p>
