One of the things that has often driven me nuts with the rise of cloud computing is the assumption that the demise of the mainframe is a foregone conclusion. I’ve often written about the reality that not all applications and data sets belong on the cloud, especially ones that reside on mainframes.
Although I have often been laughed out of a meeting for this opinion, adoption patterns have proved me correct. It’s often spun as a pushback on cloud computing itself, but it’s just pragmatism.
The truth is that we’re going to find applications and data sets (more than you think), that are not viable to move to the cloud. I call this the point of saturation, when we’re done moving most of the applications to the cloud that are practical to relocate. I’ve had mainframe applications in mind when saying that, and for good reason.
