It does, but that comes with the territory. SAP is the IBM mainframe of business software. You'll be hard-pressed to find a large multinational which don't run SAP... or have a couple of IBM mainframes to run it on. The kind of "large" which means that they don't have IT departments but IT subsidiaries, probably created by buying up a couple of tech consultancies. You know like Samsung buying Joyent, saying "never mind your public platform you'll be busy enough hosting all our data we're the only customer you'll ever need".
