# Lab 06 - Implement Traffic Management
## Lab requirements
## Lab introduction
In this lab you learn how to implement and test an internal Load Balancer. You also learn to implement and test an Application Gateway.
This lab requires an Azure subscription. Your subscription type may affect the availability of features in this lab. You may change the region, but the steps are written using East US.

In this task, you will implement an Azure Load Balancer in front of the two Azure virtual machines in the hub virtual network. Load Balancers in Azure provide layer 4 connectivity across resources, such as virtual machines. Load Balancer configuration includes a front-end IP address to accept connections, a backend pool, and rules that define how connections should traverse the load balancer.

In this task, you will implement an Azure Application Gateway in front of the two Azure virtual machines in the spoke virtual networks. An Application Gateway provides layer 7 load balancing, Web Application Firewall (WAF), SSL termination, and end-to-end encryption to the resources defined in the backend pool.
