the.com/aws private apis
an api that only talks to guests already inside your house.
means an api gateway endpoint reachable only from within a vpc, so it never touches the public internet.
from aws api gateway launched in 2015 public-only, and as enterprises pushed internal microservices into the cloud, amazon added the private endpoint type in 2018 via vpc endpoints powered by aws privatelink.
access routeonly through an interface vpc endpoint, never a public url
backbone techruns on aws privatelink, same as private rds and s3 access
policy layerresource policies can restrict calls to specific vpcs or accounts
