2. vCloud Cell Design Examples : 2.1 Load Balanced Cell Configuration : 2.1.1 Background
   
2.1.1 Background
A vCloud Director cell is comprised of Red Hat Enterprise Linux (supported versions as documented in the VMware Compatibility Guide) with installed and configured VMware vCloud Director binary files. This server becomes the portal for the vCloud Director environment, for both administrators (providers) and users (consumers) of the vCloud.
This example architecture covers the following considerations:
*Shared Transfer Space.
*Load Balancer setup.
*SSL offload for certificates and SSL to cells.
*Load balancer health check rules.
*External URL settings in vCloud Director.
