每个云实例是否都有自己的IP
对于运行 Apache 的云实例，我猜测云有一个 IP 地址。
使用云的好处之一是扩展，但我不确定扩展是如何发生的。我认为新实例会自动创建以适应流量的增加。如果这是正确的（如果我错了请纠正我），那么这是否意味着每个新实例都会有自己的 IP 或者什么？因为如果是这样的话，当将域指向云时，事情就会变得更加复杂。
For a cloud instance that runs Apache, I'm guessing the cloud has an IP address.
One of the benefits of using a cloud is scaling, but I'm not sure how that scaling happens. I thought that new instances are created automatically to accommodate rise in traffic. IF that's correct (correct me if I'm wrong), then does that mean that each new instance would have its own IP or what? because if that's the case, it would complicate matters a lot when pointing a domain to a cloud.

云位于负载均衡器后面，该负载均衡器能够将流量重定向到 Apache 服务器的不同衍生实例。因为您可以根据收到的流量来增长和缩小任意数量的服务器。
The cloud sits behind a load balancer which is able to redirect traffic to different spawned instances of Apache servers. In that since you can grow and shrink to any number of servers based on how much traffic you are receiving.
