居然是在補進度 XDDD 這是去年 AWS re:Invent 發表的功能:「New – Inter-Region VPC Peering」,在去年的時候也有提到了:「AWS 總算推出跨區 VPC Peering 了...」。

不過當時不確定跨區域時怎麼處理傳輸加密 (或者沒有處理?),這邊 Jeff Barr 補充提到了一些細節:

Data that passes between VPCs in distinct regions flows across the AWS global network in encrypted form. The data is encrypted in AEAD fashion using a modern algorithm and AWS-supplied keys that are managed and rotated automatically. The same key is used to encrypt traffic for all peering connections; this makes all traffic, regardless of customer, look the same. This anonymity provides additional protection in situations where your inter-VPC traffic is intermittent.

這樣架構會簡單不少,不需要自己再疊一層確保加密這件事情 (因為當時沒翻到資料說有加密...)。
