I happen to spend a fair amount of time in and around non-tech Fortune 500 companies.  Almost all of them still have either their own data centers, or a &quot;we&#x27;ll run your mess for less&quot; type contract (non-cloud) with companies like Rackspace, HP, etc.  I suspect the same applies for government agencies at all levels.<p>I would guess that a fair amount of the potential cloud growth is in migrating all of that to the cloud, either as an actual migration, or as some new solution built in a cloud that retires an in-house hosted solution.<p>The eventual consolidation of all of that into a pretty small number of big players (Amazon&#x2F;Google&#x2F;Microsoft) is a bit concerning in that the reduced diversity of solutions opens up some security, reliability, competitive cost, etc, concerns.
