关于 WebSphere Application Server 集群?

About the WebSphere Application Server cluster?

集群:

A logical grouping of one or more functionally identical application server processes. A cluster provides ease of deployment, configuration, workload balancing, and fallback redundancy. A cluster is a collection of servers working together as a single system to ensure that mission-critical applications and resources remain available to clients.
Clusters provide scalability. For more information, refer to additional documentation that customer support may provide that describes vertical and horizontal clustering in the WebSphere Application Server distributed environment.

以上是WebSphere集群的说明。在 WebSphere 世界中,一个单元可以有一个或多个集群。我想知道在 WebSphere 中什么情况下一个应用程序应该部署在一个以上的集群中?

不能将完全相同的应用程序部署到多个集群,如果您需要更多处理能力,只需向集群添加成员即可。

我想到部署到第二个集群的少数几个原因之一,可能是使用不同的应用程序版本 - 查看 post 以了解部署多个版本的更多详细信息和限制同一个应用程序。
