I am exploring AWS Global Accelerator. The documentation says that we can put ELB (ALB or NLB) behind the AGA but it also says that
- ALB can be in private or public facing
- NLB can only be public facing
Does anyone know why NLB is expected to only be public facing while an ALB can be in private subnet as well? Thanks!
I tried to find on the web but could not find satisfactory answer. There is a similar question: https://repost.aws/questions/QUahnyBTcxQXywDFkqUHZkJQ/global-accelerator-nlb-and-private-subnets but it does not give the reasoning.
