ELB backend authentication.

[ishan-sharma]

This a FAQ from AWS wesbite, I am not able to understand, the meaning of the question, in terms of what do they mean back end server authentication? and when answer is a no then why does aws FAQ touch the encryption when the question is about Authentication, as I understand authentication and encryption are two different computer terms.

Q: Is back-end server authentication supported with Network Load Balancer?

A: No, only encryption is supported to the back-ends with Network Load Balancer.

Hi Ishan,

You can enable authentication of your registered EC2 instances if you use HTTPS or SSL for your back-end connections. You can then use the authentication process to ensure that the instances accept only encrypted requests, and to ensure that each registered instance has the correct public key.
