Проверка использования внутренней сети

Я привыкаю к ​​облачным вычислениям, особенно к Amazon Web Services (AWS).

AWS имеет концепцию регионов и зон доступности. Все зоны доступности региона связаны специальной внутренней сетью.

Используется ли эта внутренняя сеть автоматически при передаче данных в пределах региона?

Например: 1) Я делаю запрос HTTP-GET от EC2 к S3, чтобы получить файл. topic / gce-обсуждение / ex8roHMubLY
