Simple question on ALB and NAT gateway traffic

[johntwei]

In the document, I saw these:
•A pair of NAT gateways (one in each zone) to handle outbound traffic.
•An Application Load Balancer (ALB) to the public subnets to handle inbound traffic.
I believe these two statements are independent. Meaning:

• internet access request will go out through NAT gateway
• external request from internet to ESC services will come through ALB, and response get sent back through ALB as well.
  It does not mean that external request will be returned through NAT gateway. Is this correct?

Correct.
