Re: Private cloud needed today, public cloud has long term economy of scale
OK, ye we are in definite agreement. i have actually written on several occasions that IT will be out of teh business of the datacenter in 5 - 10 years. i think i have an article on IW that discusses that. i wrote that a few years ago, while my earlier predictions was that there would be no need ofr on-premises anything, i find myself having to revise that statement A LITTLE. i still think that overall public clouds will win this battle no question in my mind, BUT, i now believe that a subset of an organization's most valuable assets will remain on-premises.
If you take the Zynga example as a model for the conversation, they satrted off 100% on AWS and then pulled back in some high valued assets. they also had some challenegs that they can overcome better internally. Sure, public clouds will get better, but i think solutions like Nebula and VMware's upcoming Marvin will server enterprise IT in maintaining an on-premises footprint for high valued assets.
Personally, i think security is exagerated, i am willing to wager that public cloud security is significantly better than the best run enterprise IT environment, but that opens up padora's box :)
