Over the last two decades, I have suffered and suppressed the enormous amount of pain caused by installing software and writing installation scripts. The pain caused me to miss many dinners, parties, and picking up the kids. We are some distance from just being able to click a single file to execute software but the annoyance of loading and installing software is rapidly being reduced in complexity. This reduction is resulting in some drastic shifts in software of all types, but especially in the cloud.
When you have millions of computers and millions of software installs, the motivation to simplify running software is large. No sacred cows – virtualization, data storage, windows registry everything related to installing software is going to change for the better.
