Legacy .NET

| Microsoft has published a blueprint for the next
generation of computing services, the ".NET" strategy. Although mainframes are
not well represented in the blueprint documents, the architecture is ideal for bringing
legacy mainframe applications forward into this next generation of computing alongside
distributed platforms. Green screen applications can be running on Palm Pilots and WAP
cell phones as well as being downward compatible with the old 3270 style terminals. Old
batch job streams can feed push processing to Internet clients as well as providing paper
reports on greenbar. Technically, there is a cost effective evolutionary path, either
through re-engineering or renovation of the current system. But before we can consider how
to do this, we must first answer the question of when it makes business sense to perform
this evolution and when not. |
