Validation function through AWS lambda (prevent "oopsie" mistakes) ClientID can be for everything, for a service, or for an individual host. Use the client for ECS/EKS as it caches, call out to 2772 port (always use something that caches) https://docs.aws.amazon.com/appconfig/latest/userguide/appconfig-integration-containers-agent.html Is there an automatic caching agent for EC2 for AWS AppConfig, like EC2/EKS? Freeform configuration can be random text, relies on the service to parse out feature flags (this is what the helper python library does?) AppConfig can pull configuration from Parameter Store (so you can retarget from boot to runtime) Parameter Store is for individual parameters, but doesn't have the concept of an overall configuration for an application. AppConfig does, and can pull individual parameters from a number of locations, including Parameter Store. Can use HOCON to set several logging levels at once
