I have an OpenStack server with Vms. I have a number of instances in AWS. The VMs in both cases need to see each other.
I could setup Tinc or OpenVPN on VMs but this seems prone to failure.
I've read about Neutron/VPNaaS, but the documents I've read assume 'multiple OpenStack hosts' and don't talk about connecting to an AWS VPN Gateway.
Is there documentation for 'VPNaaS - AWS'? Another solution I'm not seeing?
