What is the difference between Network Load Balancers (NLB) and Application Load Balancers (ALB) in AWS?

Question

Accepted Answer

NLB and ALB are both AWS load balancers, but NLB operates at the transport layer while ALB operates at the application layer.

NLB is designed for extreme performance and low latency, making it suitable for TCP and UDP traffic.
ALB provides advanced routing capabilities and supports HTTP, HTTPS, and WebSocket protocols.
NLB supports static IP addresses, while ALB uses dynamic IP addresses.
ALB supports content-based routing and can route requests based on URL path or host headers.
ALB supports integration with AWS services like AWS Lambda and Amazon ECS.

Accepted Answer

NLB just forwards the request where as ALB examines the contents of tge http request header to determine where to route the request. ALB does content based routing
