 | **Description** | A public load balancer maps the public IP and port of incoming traffic to the private IP and port of the VM. Load balancer maps traffic the other way around for the response traffic from the VM. You can distribute specific types of traffic across multiple VMs or services by applying load-balancing rules. For example, you can spread the load of web request traffic across multiple web servers.| An internal load balancer distributes traffic to resources that are inside a virtual network. Azure restricts access to the frontend IP addresses of a virtual network that are load balanced. Frontend IP addresses and virtual networks are never directly exposed to an internet endpoint, meaning an internal load balancer can't accept incoming traffic from the internet. Internal line-of-business applications run in Azure and are accessed from within Azure or from on-premises resources. |

 An **[internal (or private) load balancer](./components.md#frontend-ip-configurations)** is used in scenarios where private IPs are needed at the frontend only. Internal load balancers are used to load balance traffic inside a virtual network. A load balancer frontend can be accessed from an on-premises network in a hybrid scenario.
