Will correct it. Thanks.

[@GauravSingh-zg4mm]

As per my understanding, NLB works on Transport (TCP) Layer and same has been told in OSI model Explanation !! Kindly correct me @Analogies cloud in case required .. Thank you!

[@AnalogiesCloud]

Don't understand your question/confusion. Can you elaborate?

[@GauravSingh-zg4mm]

@@AnalogiesCloud I mean NLB works on Transport Layer rather than Network layer !!

How do we decide which one to use while designing the system? and can they be used in combination as well while architecting a bigger system?

[@AnalogiesCloud]

The choice will depend on your application requirement. aws.amazon.com/elasticloadbalancing/features/ You can add NLB in front of an ALB of needed. aws.amazon.com/blogs/networking-and-content-delivery/application-load-balancer-type-target-group-for-network-load-balancer/
