How does ALB handle HTTPS differently than NLB?

Question

Mahesh B · Accepted Answer

Application Load Balancer (ALB) handles HTTPS at Layer 7, allowing for SSL termination and advanced routing based on HTTPS headers. In contrast, Network Load Balancer (NLB) operates at Layer 4, passing through encrypted traffic without inspecting headers or performing SSL termination, making ALB more suitable for applications requiring these HTTPS features.

Gowtham Hari Dhandapani · Answer

ALB & NLB operate at different layers of the OSI model, so they handle HTTPS differently . ALB works at the application layer (Layer 7). NLB works at the transport layer (Layer 4).
