有一樣野在改變中:-
現在乜都話上CLOUD, 其實CLOUD 可以話系 CLUSTERED MAINFRAME.
不過個 OSI MODEL 部份 LAYERS 唔同左 而已
( Layer 5: Session Layer
  Layer 6: Presentation Layer
  Layer 7: Application Layer )

所以, 重溫 IBM MAINFRAME, 可能系 將來搵食既 本錢 .

Mainframe skill is a very specific skill and hardly to be replaced by cloud even unix/linux.  However, the market is very small too.

保養mainframe的成本太高了，所以雲端計算才有出路，一切看COO 同 SLA.

mainframe 本身既architecture 會系 好 proprietary 同埋 system specific.

不過 早年 既 mainframe ( 例如 ibm 360, digital pdp11 ) 所用 既 部份 technology 已經 用左系  pc 或  server 了。
