I have set up a 3-node, multi-subnet Always On Availability group in AWS, which seems to be working well. However, each node only has a single network adaptor with 3 IP addresses assigned to it (1 primary, 1 WSFC IP resource, 1 listener). Is this sufficient for high-availability, or do I need additional networks? I believe with a traditional cluster you would need multiple networks & adaptors to ensure there is no single point of failure. I'm not sure if this is the case in AWS, as I assume they have redundancy built-in at their end?

Thanks
