AWS PrivateLink restricts all network traffic between your managed instances, Systems Manager, and Amazon EC2 to the Amazon network. This means that your managed instances don't have access to the Internet. If you use AWS PrivateLink, you don't need an internet gateway, a NAT device, or a virtual private gateway.
- privatelinkをうまく使いこなせばnatがいらなくなる
- ssmのprivatelink使わない場合はエンドポイントへのアウトバウンドトラフィックを許可する必要がある
