Background: I will be setting up a small proof-of-concept Citrix Environment on Amazon Web Services for testing purposes. This particular POC will be completely on AWS and utilize a combination of free tier and paid on-demand instances. Eventually, I hope to integrate additional features such as autoscaling, a XenMobile component, and integrating it with an on-premises infrastructure for a hybrid environment. I will be breaking up this article into different parts. This article covers configuration of the AD infrastructure in our POC: Domain Controller setup, RDS licensing setup, Certificate Services setup.
