I have ALB and internet gateway for Lambda.

For lambda https access works automatically.

For ALB I can't access https.

I am not still sure though,,

I need to use ACM for ALB?, and don't need to do anything for lambda gateway??

Am I correct? and why this difference happens?

CodePudding user response：

Lambda https access, your client's https is validated against the Amazon domain, and thus uses the Amazon certificates.

ALB https access, your client's https is validated against the domain which you specify, and therefore you must provide a certificate for that; ACM is used to store your certificate.
