Virtual Private Cloud OnDemand Networking Guide

See the following use cases for using Data Center Extension with Virtual Private Cloud OnDemand:
n
When you have licenses tied to MAC addresses
n
Your virtual machine applications have dependencies on IP addresses or MAC addresses
n
You lack DNS control, which prevents DNS updates
n
To avoid invalidating existing security rules or the need to re-configure access control lists
Data Center Extension has the following requirements.
n
Extended Network Considerations:
n
Extended virtual machines use the on premise gateway.
n
All network traffic traverses the SSL VPN connection.
n
Microsoft Active Directory Sites and Services:
n
The extended network is part of the on premise site in Active Directory.
n
DNS and Active Directory communication with vCloud servers traverses the SSL VPN connection.
n
You cannot split a network between sites .
n
vApp Limitations:
n
An extended network supports 128 virtual machines per vApp.
n
An extended network supports power operations for one vApp.
You can perform power operations simultaneously on all virtual machines contained in a vApp.
