Cloud Networking is fast

You can create a complete end-to-end network from the datacenter to the cloud. All cloud servers communicate securely over SSL VPN.

Between the datacenter and the Amazon EC2 cloud is a site-to-site SSL VPN built with Vyatta. On the XenApp server in the cloud runs the Citrix Accelerator which connects back to the Citrix Branch Repeater/WANScaler at the datacenter, to accelerate data connections. The Citrix Accelerator makes cloud computing fast, Vyatta makes it secure.

The reason for using Vyatta site-to-site SSL VPN between the datacenter and Amazon EC2 cloud is there needs to be a secure network between the two for the transfer of data. The Vyatta AMI (Amazon Machine Image) can also function as a complete router and firewall. The Vyatta SSL VPN router provides security with scalability.

As you can see from the network diagram and video, complete routing from the datacenter to the Amazon cloud network is seamless. Data resides at the datacenter and is accessed, over the SSL VPN, by the Application running in XenApp. The remote user connects to XenApp, runs the application, and the application delivers the data to the remote user, quickly and securely.

To get your own cloud, go here.

    The Bridge is the most powerful extension that exists for Cloud providers.  Without it, there is no way to tie the data centers together and provide consistancy and persistant workload administration.  Looking foward to more on this topic.

    I'm trying, and failing, to understand why you bothered with vyatta in the cloud, why not just run openvpn from the xenserver straight back to the datacentre ?

      OpenVPN is not scalable when running on a Windows machine, in addition to the fact that OpenVPN does not route packets through the machine it is running on, on both sides of the VPN. The Vyatta serves as a true VPN gateway at the datacenter and in the cloud. The Vyatta supports IPSec in addition to SSL VPN, and can be configured for many other functions such as a firewall or router.
