What are the main types of load balancers based on the OSI layer they operate on?

beginner

Re-explain

There are two main types:
Layer 4 (Transport Layer) Load Balancers:

Operate at the TCP/UDP level
Make routing decisions based on IP address and port numbers
Faster and more efficient
Cannot inspect application data
Example: AWS Network Load Balancer
Layer 7 (Application Layer) Load Balancers:
Operate at the HTTP/HTTPS level
Can make routing decisions based on content (headers, URLs, cookies)
More intelligent routing capabilities
Can perform SSL termination
Example: AWS Application Load Balancer
