HN 提问:工作中大家都不敢碰的那个关键遗留系统是什么?

2 分•作者: jerrycat101•3 个月前
我最近在工作中继承了一个旧的电话和呼叫中心系统。它运行在 Elastix/CentOS、一个定制的 Windows 应用程序、MySQL、带有模拟设备和静态 IP 的 GSM 网关上,几乎没有任何文档。 奇怪的是,它运行得非常好。问题在于,现在没有人完全理解所有的依赖关系,并且更改错误的东西可能会影响公司的很大一部分。因此,目前我正在记录所有内容,改进备份,将其虚拟化并隔离,然后再尝试替换。 有没有其他人继承过一个让所有人都害怕触碰的关键系统?

I recently inherited an old phone and call centre system at work It runs on Elastix&#x2F;CentOS, a custom windows app, MySQL, GSM gateways with analogue devices and static ips, with almost no documentation at all.<p>The strange thing is, it works really well. The problem is that nobody fully understands every dependency anymore and changing the wrong thing could affect a large part of the company so for now am documenting everything, improving the backups virtualising it and isolating it before attempting replacment.<p>Has anyone else inherited a critical system that everyone was afraid to touch?
