Ok I get it, dump your mainframe and as400's and use the someone else's server farm who know where, but, what about connectivity. Use internet legacy systems. If the cloud is based on connectivity, wouldnt it be quicker to have cat5 going down the hall, instead of ethernet hubs to out slobovoia? That is not even considering that you have no ability to modify anything since it technically is not their or yours. And now azure..what the heck, get the plc devices and refrigerators connected too, I wont be able to turn my car on or toaster. Remember stuxnet?
