禁止RAM用户为ECS实例分配公网IP

固定公网IP与弹性公网IP以便捷的方式为ECS实例提供了公网访问的能力，但对于拥有大量云资源的企业，随意为ECS实例分配公网IP会增加实例从公网被攻击的风险，同时会使您的网络架构变得混乱，难以管理，建议您指派网络管理员，将网络相关的操作授权给他们进行统一规划。本文将介绍如何使用RAM权限策略禁止RAM用户为ECS实例分配公网IP。

固定公网IP

您可以为ECS实例分配固定公网IP，来满足ECS实例的公网通信需求。本文介绍如何为ECS实例分配，更换固定公网IP以及固定公网IP的释放与回收。

服务迁移时保持公网 IP 不变

阿里云提供了将原 ECS 实例所分配的固定公网 IP 转为弹性公网 IP（EIP），且公网 IP 地址不变的能力。您可以将转换后的 EIP 绑定到负载均衡 SLB 或其他 ECS 实例上，在不影响业务的情况下完成水平扩容、服务迁移。
