Hey guys, a basic question… does NLB serve http requests?
No, I believe it is only layer 4 traffic - tcp
Can a NLB point to the ALB
What do you mean serve? I mean you can chuck HTTP traffic through it but it’s handling stuff at layer 4 rather than layer 7, you’d need to point the NLB at something that’s going to interpret and handle the HTTP requests/responses (e.g., nginx, traefik etc.)
What you need to ask is why would I use an NLB over an ALB?
Static IPs is a good reason
But yes, you recently can do it
yeah, never done it but I believe you can also use a global accelerator to achieve a static IP ALB: https://dev.to/aws-builders/how-to-assign-static-ip-on-application-load-balancer-using-aws-global-accelerator-4chf
You could stick a global accelerator in front of an NLB in front of an ALB if you are really into encapsulating requests
