Understanding Windows Azure Virtual Network and Windows Azure Connect

Uploaded by windowsazure on 18.06.2012

The cloud gives you an almost infinite set of computing resources. Using these
resources you can build new applications, migrate existing applications from
a corporate datacenter, or extend your datacenter capacity
No matter how you choose to use the cloud
chances are you'll need to connect applications or machines running in the
cloud with those that aren't, such as machines running in your corporate
you'll want these cross-premise connections to be really secure and also
make your on-premise and off-premise machines behave as though they're on the
same network
We call this IP-level connectivity
Not all requirements to create IP-level cross-premise connections are the
For example, a developer about to build a new Web application in the cloud might
want to store data in an on-premise SQL Server
This case needs a simple point-to-point connection that a developer can easily
Another example is when an IT administrator is thinking of increasing
the capacity of a corporate datacenter by adding Virtual Machines in the cloud
He would need a way to group these machines into logical subnets, assign
IP addresses to them and connect to them through a corporate VPN gateway
Windows Azure allows you to address both of these cases
with Windows Azure, there are 2 ways to create cross-premise IP-level
Windows Azure Connect
and Windows Azure Virtual Network
Let's first take a look at how Windows Azure Connect works. To start using the
service you first need to download and install a simple software agent on the
on-premise machine that you want to connect to Windows Azure
Then, you need to do some simple configuration on the management portal
Once these two steps have been completed a secure connection is set up
It's that simple, it takes just a few minutes to set the connection up and the
secure connection that you've created works even through your corporate firewall
Windows Azure Connect gives developers an extremely simple and easy way of
connecting their on-premise machines with Windows Azure instances running in the
Now let's look at the second method Windows Azure supports for cross-
premises connectivity
The Windows Azure Virtual Network
allows you to create a private network of machines in the Windows Azure
environment that you can assign IP addresses to and then connect to your
corporate data center through a VPN gateway device. Using this method you
can connect on-premises machines that are running Windows or other operating
systems with Linux
or Windows Virtual Machines running in Windows Azure. You get to manage the
private network that you created as though it were
a remote datacenter connected through a VPN. with the kind of control and scale that
you get using Windows Azure Virtual Network, configuration setup is best
suited for a network administrator or an IT administrator
To recap,
Windows Azure Connect offers a simple and easy way to connect an on-premise
machine in the cloud in a point-to-point fashion
Windows Azure Virtual Network, on the other hand, allows you to connect your
on-premise environment to a virtual network of machines in Windows Azure in
a manner that is secure scalable and gives you complete control.
