With Azure Load Balancer you can scale your applications and create high availability for your services.

Load Balancer supports inbound and outbound scenarios, provides low latency and high throughput, and scales up to millions of flows for all TCP and UDP applications.

You can use Azure Load Balancer to:

• Load-balance incoming internet traffic to your VMs. This configuration is known as a Public Load Balancer.
• Load-balance traffic across VMs inside a virtual network. You can also reach a Load Balancer front end from an on-premises network in a hybrid scenario. Both scenarios use a configuration that is known as an Internal Load Balancer.
• Port forward traffic to a specific port on specific VMs with inbound network address translation (NAT) rules.
• Provide outbound connectivity for VMs inside your virtual network by using a public Load Balancer.
