High Availability

Achieving High Availability with Vyatta on the cloud (continued)

October 14, 2009

In the earlier post of building a Vyatta router on the cloud with Amazon EC2, I mentioned that I had issues with setting up a SNAT (source NAT) and made the assumption that it was either a bug or the OS image of Vyatta on Amazon.

I’ve been working through this issue with Stig from Vyatta on their forums. You can view the messages at http://vyatta.org/forum/viewtopic.php?t=2908

Achieving High Availability with Vyatta on the cloud

October 12, 2009

Over the past two weeks, I’ve been working on setting up a virtual router on the cloud with the goal of building redundancy, and achieving high availability. After working on different platforms, I’ve come to the conclusion that Vyatta is the best way to go, whether on the cloud or not.

The router is being used for site to site vpn communication between a central and remote location. There will also be an application server on either end. Your typical network setup would look somewhat like the picture below.
