Hi guys, I am looking for some feature flag solutions for our backend (completely serverless, AWS). I saw launchdarkly but it seems i need to use a redis cluster to avoid calls to launchdarkly everytime the lambda is coldstarts. I am very first time planning to use feature flag, what do you guys use ?

Remember that a lambda does not coldstart on every invocation

do you guys use it ? I am looking for something which is suitable for serverless architectures, any suggestions ?

I haven't used LaunchDarkly but yes it's suitable with serverless and you don't need a redis cluster with it

we are using dynamodb, and you mean like this ? https://docs.launchdarkly.com/sdk/features/storing-data/dynamodb i will check more then , thanks !

check this out if you haven't already: https://docs.launchdarkly.com/guides/best-practices/serverless

thanks this looks better !

We use LaunchDarkly but it gets super pricy super fast … So we are moving to https://flagsmith.com shortly

you can also go simple and use a database table/collection. we use postgres still, fast enough. i imagine using dynamodb would be even faster.

@Sourav Sarkar have a look into AWS AppConfig. There's even a lambda extension for it. Application config gets updated even in a warm lambda. It's a great serverless option.
