Default Setup for Gateways and Networks
The default setup for gateways and networks varies in vCloud Air depending on which service you
purchased—Dedicated Cloud service or Virtual Private Cloud service.
See Types of vCloud Air in vCloud Air User's Guide for information about the service options.
With both services, you configure networks for each virtual data center. Virtual data centers use the
VMware vCloud Networking and Securityy Edge Gateway (referred to as “the gateway” in this guide) to
provide external network connectivity. The following components comprise the default setup for networks
and gateways in vCloud Air.
VMware manages the external network for connectivity to the Intranet. In vCloud Air, customers create and
manage networks (utilizing the embedded VXLAN technology).
Gateways
When you subscribe to a Virtual Private Cloud service, VMware creates your virtual data center for you and
adds a gateway to that virtual data center. When you subscribe to a Dedicated Cloud service, you log into
the vCloud Air console and create your first virtual data center. When you allocate a public IP address to
your virtual data center, vCloud Air creates a gateway in that virtual data center.
By default, a gateway has the following properties:
n
Compact configuration
n
High availability enabled
n
Multi-interface mode enabled
n
An internal network with an internal IP address and subnet
When you subscribe to the Dedicated Cloud service, you can deploy additional gateways in a virtual data
center. When you subscribe to the Virtual Private Cloud service, your virtual data center can have only one
gateway.
A gateway supports 10 interfaces, but one interface is reserved for access to the external network. You
configure networking for a gateway by using the remaining nine interfaces. If a virtual data center requires
additional interfaces for its networking configuration, add additional gateways (only possible for the
Dedicated Cloud service).
Networks
When you subscribe to the Dedicated Cloud service, you are allocated three public IP addresses to configure
access to the Internet. When you subscribe to the Virtual Private Cloud service, you are allocated two public
IP addresses. You can purchase additional public IP addresses at any time through your Subscription
Services in My VMware.
When VMware creates the virtual data center for your Virtual Private Cloud service or you allocate a public
IP address to a virtual data center that you create for your Dedicated Cloud service, the virtual data center
has the following networks by default:
n
DATACENTER_NAME-DEFAULT-ROUTED: a gateway network because it is connected to a gateway
and virtual machines on this network can connect to the Internet.
n
DATACENTER_NAME-DEFAULT-ISOLATED: an internal network that is not connect to a gateway;
virtual machines on this network are not reachable through the Internet.
A private IP address pool is assigned to each network.
