Virtual Private Cloud OnDemand Networking Guide

vSphere is the foundation on which Virtual Private Cloud OnDemand is built. On top of vSphere, Virtual
eXtensible Local Area Network (VXLAN), part of VMware vCloud Networking and Security, provides the
functions necessary to implement a flexible virtual network in the data center. VXLAN—dynamic and
encapsulated—provides the ability to deploy networks in Virtual Private Cloud OnDemand rather than
requiring complex VLAN architectures. VXLAN technology allows compute resources to be pooled across
non-contiguous clusters and segmented into logical networks attached to applications. VXLAN allows for
full encapsulation at Layer 2, providing network security. Also part of vCloud Networking and Security, the
gateway virtual appliance enables networking services, such as the firewall, NAT, load balancer, and a VPN
endpoint.
The Virtual Private Cloud OnDemand Web UI is the primary portal for managing gateways and networks.
Additionally, you can use vCloud Director to manage your gateways and networks at a more detailed level.
The Virtual Private Cloud OnDemand Web UI provides single sign-on access to vCloud Director.
Capacity for Gateways and Networks
Gateways and networks in Virtual Private Cloud OnDemand are subject to the following capacity
limitations:
Resource Limit
Maximum gateways/Virtual Data Center 1
Routed Networks/Gateway 9
Isolated Networks/Gateway Unlimited
Networks/Virtual Data Center 20
Virtual NICs/Virtual Data Center 100
Network Objects/Virtual Data Center 100
Public IP Addresses/Virtual Data Center 5
Public IP Addresses/Customer 20
When you reach your capacity and resource limits, file a support request. Log into My VMware to file
support requests for Virtual Private Cloud OnDemand.
See Account Support in vCloud Air – Virtual Private Cloud OnDemand Getting Started for information.
See also the My VMware Help ( ) for information.
Default Setup for Gateways and Networks
Virtual data centers use the VMware vCloud Networking and Security Edge Gateway (called “the gateway”
in this guide) to provide external network connectivity.
The following components comprise the default setup for networks and gateways in
Virtual Private Cloud OnDemand. VMware manages the external network for connectivity to the Intranet.
In Virtual Private Cloud OnDemand, customers create and manage networks (utilizing the embedded
VXLAN technology).
