Loose Bruce Kerr pretty much says it all, with some apology to Joni Mitchell. No apologies needed to the juggernaut that is cloud services. This is a true revolution in technology, much the same as the move from mainframes to networked PCs and now back to something of a mainframe in the cloud. True, there are security and connectivity issues to be addressed. But once cloud services become established as mainstream, the idea of actually buying and upgrading software will seem as quaint as address and data switches on the front of a computer.
Are you missing out by pooh-poohing the availability of cloud computing, storage and networking? You could be saving a considerable amount of money with MPLS cloud networking to link multiple sites. If you are not ready to buy your computing from the cloud, perhaps the intermediate step of managed colocation could be a big and staff saver. It’s good to at least look at both sides, now... and in the future.
