 Lab 1: Deploying F5 Distributed Cloud Proxy Services to Securely Deliver a Public Endpoint
 ==========================================================================================
 
-This lab will focus on the deployment and security of an existing hosted application using F5
-Distributed Cloud Platform and Services.  This lab will be deployed in a SaaS only
-configuration with no on-premises (public or private cloud) elements.  All configuration
-will be made via the F5 Distributed Cloud Console and within the F5 Distributed Cloud Global
-Network services architecture.
+You just landed a new role and your company needs you to deploy an application. They want to use F5 Distributed Cloud (F5 XC) for its access and availability globally. The developers inform you that the application lives in both AWS and in Azure.
+
+In this lab you will be creating a global application load balancer with an ingress endpoint on a F5 XC Regional Edge (RE) and will configure it with an origin server using the application's public IP in Azure. Additionally, as you test the application, you'll use the F5 XC Console to view telemetry data. The final task will be to add a Web Application Firewall (WAF) policy to protect the application from malicious attacks, and then observe the security events generated by the WAF.
