HATS also allows programmatic interfaces to convert the identified content in these host applications into any other format.
水平集群：在不同的主机上运行应用服务器的多个节点或实例。
Horizontal clustering: Running multiple nodes or instances of an application server on different hosts.
例如，它可以导航一个主机应用程序屏幕来显示用户需要看到的第一个屏幕，省略中间的所有屏幕。
For example, it can navigate the screens of a host application to display the first screen the user needs to see, bypassing all the screens in between.
在这种情况下，您需要创建一个屏幕识别条件，用来识别主机应用程序中的某个屏幕。
In that case, you will need to create screen recognition criteria that will recognize a single screen in your host application.
在为某个自定义定义屏幕识别时，您必须通盘考虑整个主机应用程序。
When defining screen recognition for a customization, you must take your entire host application into consideration.
可是，他们的企业里有着网状互联的遗留应用和异构环境，比如主机、AIX等等。这些系统阻碍了他们向公共云的整体跨跃。
However, they have a web of interconnected legacy applications and heterogeneous environments including mainframe, AIX, etc. that prevent them from making a wholesale jump to a cloud provider.
即使您能像生产环境一样模拟您的新环境，但只有一个环境可以与应用程序的主机名关联。
Even though you will be mocking up your new environment as if it were production, only one environment can be associated with the host name of the application.
相反，您使用HATS全局变量以确定主机应用程序的状态，并确定何时应用您的多个呈现集。
