21st Century Software

在长期运行的 IBM Z 环境中，只有当供应商能够证明、恢复并将下一次变更交回运营，且不扩大故障面时，它才是有用的。21st Century Software 正是处于这一狭窄通道：其价值不是对大型机的怀旧，而在于其 z/OS 和 VSEn 工具能否帮助受监管的运营团队以更少的不确定性，从计划维护或故障响应过渡到可接受、可恢复的状态。

In long-lived IBM Z estates, a vendor is useful only if the next change can be proved, recovered and handed back to operations without expanding the failure surface. 21st Century Software sits in that narrow lane: its value is not nostalgia for the mainframe, but whether its z/OS and VSEn tools can help a regulated operations team move from planned maintenance or failure response to an accepted, recoverable state with less uncertainty.
