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. Load Balancer distributes new inbound flows that arrive on the Load Balancer's frontend to backend pool instances, according to rules and health probes.

In this lab, you will create a load balancer and configure it to serve traffic to a web application. You'll also create the necessary resources the Load Balancer will need to use in order to serve traffic, including an Azure Virtual Machine, Virtual Network, Network Security Group and more.
