AZ-104: Microsoft Azure Administrator Full Course - Public Load Balancer

The video tutorial explains the concept of a public load balancer, which maps public IP addresses and port numbers to private IP addresses and port numbers of virtual machines. It discusses how load balancing rules can distribute traffic across multiple virtual machines or services, using web servers as an example. The tutorial highlights the customization options available for public load balancers, which are typically exposed to the Internet on specific ports like 443. The video concludes with a brief mention of internal load balancers, which will be covered in the next lesson.

What is the primary function of a public load balancer?
