使用VPC附加网段实现EIP网卡可见

EIP 默认以 NAT 方式映射到 ECS 实例的私网 IP，操作系统内仅可见私网地址。在部分业务场景中，应用程序要求公网 IP 直接配置在网卡上，即 EIP 网卡可见。

阿里云独门绝技之“EIP网卡可见模式”

弹性网卡是一个可以附加到阿里云VPC内ECS上的一个弹性网络设备，我个人认为这里弹性的意思有两层：一是可以弹性的申请和释放二是可以在不同的ECS之间弹性迁移弹性的迁移一个网卡有什么用？对于像ECS这样的虚拟服务器来说，要多少网卡有多少网卡，反正都是虚拟的。其实真正要迁移的是网卡绑定的IP地址，尤其是公网的IP（EIP）。阿里云EIP支持绑定到弹性网卡上，因此就可以随着弹性网卡在不同的E...
