Casually arrogant, and wrong...
Don't get me wrong, I would like to move my org to "cloud", but articles like this make things harder, not easier. See full disclosure below
You can say what you like, but on premises definately includes in my own building. Always will. And not just if you are "...a big company that can afford suitably protected premises, mean servers and storage...". Many smaller companies do not have a business requirement for the levels of service and uptime that a commercial DC offers. Please remember that making a business case against this is, at present, impossible for an organisation similar to mine. And that is discounting the requirements for fast and reliable access to data: wire speed lines are hideously expensive, unavailable away from urban sprawl (no real bandwidth/low latency connections commercially available, let along affordable at over 80% of our offices) and at least 4 additional layers of single point of failure further away from my endusers. Given the upstream connectivity SLA levels (not even 4 nines - and they've not hit 2 nines so far this calendar year) that is a risk I cannot accept.
The Public / Private apologetic is equally flawed, for similar reasons: that may be the definitions you'd like to see us working to, but in the real world, well, get real.
This piece feels like an "infomercial/advertorial" targetted at non-IT decision makers in huge organisations by a sales person for a coud provider, rather than something the average IT Joe can use (aka articles by Mr Potts). Not up to the quality I expect on El Reg.
Added to my "ignore all from" list.
Full disclosure: I run infrastructure for several organisations (small and SME, public sector, from 40 to 700 staff, 2 to 43 offices), and provide some support several others. I've have already moved one of the small orgs fully to the cloud... because it made financial sense, but the larger org that employs me won't be going anytime soon: Information Management policy (not IS reponsibility), local data processing (GIS - BIG data in its volume meaning) and cloud storage/data movement costs (70TB rising 12% annually) and connectivity restrictions (DIRE speeds, poor delivery against SLA) all mean that commercial cloud solutions are not financially viable. For example: today we evaluated quotes for off-site cloud backup for video storage (5TB, rising to 12TB over 3 years), £350pcm, or using commercial servers in existing buildings, £4000 capital and elecricity costs (connectivity costs same in both examples).
