What is the fundamental difference between Cloudflare Tunnel and Cloudflare Load Balancer?

Cloudflare Tunnel establishes an outbound-only connection from your origin server to Cloudflare's network, effectively bringing your private resources onto Cloudflare without opening inbound firewall ports. Cloudflare Load Balancer, on the other hand, sits in front of multiple publicly accessible origin servers (or pools of origins) to intelligently distribute incoming traffic, enhance availability, and provide failover capabilities. The tunnel focuses on secure, private origin exposure, while the load balancer focuses on intelligent traffic distribution for multiple origins.
