Über einfache VPCs hinaus umfassen fortgeschrittene AWS-Netzwerkkonzepte Netzwerke verbinden (VPC Peering, Transit Gateway, VPN, Direct Connect), privaten Service-Zugriff (VPC Endpoints, PrivateLink) und das Entwerfen sicherer, skalierbarer Netzwerkarchitekturen über VPCs, Accounts und On-Premises-Umgebungen.
VPCs und Netzwerke verbinden
VPC PEERING → connect two VPCs privately (1-to-1; doesn't transit; can get complex at scale)
TRANSIT GATEWAY → a central hub connecting MANY VPCs (and on-prem) — scalable
hub-and-spoke networking (vs a mesh of peerings)
VPN → encrypted connection over the internet between AWS and on-premises
DIRECT CONNECT → a DEDICATED private physical link to AWS (consistent, high bandwidth,
low latency — for serious hybrid/on-prem connectivity, bypassing the internet)
