LD (and the other feature flag services), allow flighting, population management etc. as well.
It's unclear to me, where the value is here as a "config" solution vs the feature flag solution they offer.
LaunchDarkly for sure is a complete solution with a lot of options.
It depends on the use case and the experience. As you said, you are using S3 as object storage and Cloudfront as a CDN to deliver the assets, but not everyone has your knowledge and I feel there is a need for a simple solution where: - store the config as a JSON (or feature flags if you will) - store the assets (without having to manually or programmatically invalidate the cache) - retrieve the config via API - or - push the config in real-time and let your code react to this event
I hope I was clear enough, if not, just let me know.
