In my 35 years in IT, I have never seen so much simultaneous change in technology. Every part of the IT stack is in transition - end user devices, networks, application design, virtual server software, physical server design, storage systems, and even storage media. Some of these transitions are well underway and will accelerate in 2015 while others are just starting to emerge. Either way, buckle up! IT is going to be a wild ride in 2015.
