If any given server is unavailable or too busy at the time the request arrives, the cluster transparently passes the request to a server capable of handling the work.
如果特定服务器在请求到达时不可用或过于繁忙，集群可以透明地将该请求传递给其他可用的服务器。
If users often experience response times of more than one second, the server is generally considered to be too busy.
