AWS has a native service for this called AppConfig and has agents that can pull and cache flag values so your services only need to make localhost requests.
AH nice, I was not aware of this. Thanks (It is expensive, though...)
Expensive?? Really? One of the cheapest services around.
$0.0000002 per configuration request
Depending on when you’re evaluating it’s a per request overhead. You might/provably have multiple flags per request. Compared to a lambda invocation that pushes a config file to every container if it changes, it’s expensive.
