# AWS::EVS::Environment VcfHostnames
<a name="aws-properties-evs-environment-vcfhostnames"></a>

The DNS hostnames that Amazon EVS uses to install VMware vCenter Server, NSX, SDDC Manager, and Cloud Builder. Each hostname must be unique, and resolve to a domain name that you've registered in your DNS service of choice. Hostnames cannot be changed.

VMware VCF requires the deployment of two NSX Edge nodes, and three NSX Manager virtual machines.
