We are migrating from physical computers to the cloud using AWS. We have been successful in getting five g4dn.4xlarge instances setup and vmix installed. The challenge we are running into is getting the servers to see each other and share NDI.

Any guidance on this configuration would be appreciated.

There is a bit of a workaround that you need to do for NDI on AWS.

- First of all, make sure all your devices are within the same VPC. I also suggest having an Elastic IP, otherwise in the next step you'll have to reconfigure each time you fire up your devices.

- Download and install NDI Tools on every machine.
- Configure NDI Access Manager
- Add the IPs for all your vMix devices.
- Restart your systems, open vMix. You should see the devices.

Yep. An elastic IP is a static public IP. I believe AWS charges about $1/month for those. Though, I don't suggest communications between your vmix instances need static public IPs, you CAN do static private IPs just by changing your VPN settings. I would put your private IPs in NDI Access Manager.

I do setup static public IPs though on all of my vmix instances just for ease of access on the outside. I think AWS charges like $1 / Elastic IP / mo (something like that).
