AWS deployment

[DaveA66]

Hi

I am considering using AWS for 3CX deployments, we currently use GCP

With AWS, do all 3CX installs get installed via the same AWS account?
If so do they all get installed into the default VPC and do I get to select which subnet?

If they all go into the same VPC I guess they are isolated from each other, data wise, and cannot 'talk' to each other unless I specifically allow that in the security group?

Thanks!
