AWS 推出 Cloud Native Networking,在每個 Container 內都有自己獨立的網路卡

AWSAmazon ECS 變得更好用了:「Introducing Cloud Native Networking for Amazon ECS Containers」。

Today, AWS announced task networking for Amazon ECS. This feature brings Amazon EC2 networking capabilities to tasks using elastic network interfaces.

awsvpc 模式下會給每個 container 一個獨立的網路卡 (Elastic Network Interface,ENI):

這樣有兩個好處。第一個是 port 就不需要拆開,所有 container 如果都是跑 nginx,都可以跑在同一個 port (80 或是 443),這對於前端應用程式會簡單一些。第二個整合了 AWS 的 security group,這對在 AWS 上本來就會使用 security group 的大多數人來說就可以輕鬆整合了。
