Does services in 2 amazon accounts connects over internet?

Question

Hello,

We have 2 different amazon accounts. First account has EKS (where application is hosted) and other has SQL DB. Does data between these 2 services flow on some AWS backbone network (like Azure) or it flows over internet.

Regards,

Accepted Answer

The so-called Internet does not pass through. Communication between AWS services is considered to go through Amazon's global network.

A VPC FAQ asks, "Does traffic go over the internet when two instances communicate using public IP addresses, or when instances communicate with a public AWS service endpoint?"
The answer is as follows.

> No. When using public IP addresses, all communication between instances and services hosted in AWS use AWS's private network.
