AWS ALB vs NLB: Comparing Load Balancing Solutions

Choosing between ALB and NLB depends on your specific application requirements:

Use ALB if you need advanced routing capabilities, support for modern web protocols (HTTP/2, WebSockets), SSL termination, and integration with WAF for web applications.

Use NLB if you need high performance, low latency, support for TCP/UDP traffic, static IP addresses, and the ability to preserve the client source IP address.

By understanding the strengths and use cases of each load balancer, you can make an informed decision that best suits your application's architecture and performance requirements.
