Using a Public Load Balancer in Azure provides the significant benefit of allowing users to access services over the internet. This functionality is critical for applications that need to provide public-facing services, ensuring that users can reach those services from external networks. The Public Load Balancer serves as a gateway for incoming traffic, distributing it across multiple virtual machines or resources in the backend. This enhances availability and scalability, as it can efficiently manage varying levels of traffic by routing requests to the appropriate backend instances.

The ability to expose services to the internet is essential for many applications, particularly those requiring external client interaction, such as web applications, APIs, or any service that demands accessibility from outside the organization's private network. This feature of the Public Load Balancer makes it a foundational component in enabling reliable, balanced access to critical services for users across the globe.
