但您真正想要的，是一系列服务；服务器只是实现该目的一个手段。
What you really want, though, is a constellation of services; servers are just a means to that end.
在我们给出的简单示例中，由于服务器进程是一个CICS事务，直接在多个CICS区域中运行多个服务器事务副本就可能将队列深度保持在很低的水平。
In our simple example, since the server process is a CICS transaction, simply having multiple copies of the server transaction running in multiple CICS regions would keep the queue depth very low.
例如，服务器事件是一个回调函数，它是在新的客户端连接服务器时调用的。
For example, the server event is a callback method that is invoked when a new client connects to the server.
例如，当LDAP服务器对一个用户进行认证时，认证权威机构是LDAP服务器—即使LDAP服务器可能正在使用SAML来传送认证。
For example, when an LDAP server authenticates a user, the authentication authority is the LDAP server even though the LDAP server may be using SAML to communicate the authorization.
