Christian Perry has an article in Processor Magazine that I contributed some
quotes to. The article is about the ongoing debate about the merits of public
and private clouds in the enterprise.
One of the assertions that VMWare made at last week’s VMWorld conference is
that secure hybrid clouds are the future for enterprise IT.
This is a sentiment I agree with. But I also see the private part of the
hybrid cloud as an excellent stepping stone to public clouds.
Most future enterprise cloud apps will reside in the hybrid cloud; however,
there will always be some applications, such as bursty web apps, that can
benefit tremendously from the basic economics of public clouds.
This year’s VMworld conference saw the announcement of VMware’s new
vCloud Director product, a culmination of the vision for the cloud computing
the company articulated last year and a significant step forward in providing
a true enterprise-grade cloud. This is virtualization 2.0—a major rethink
about how IT should deliver infrastructure services. VMware believes that the
secure hybrid cloud is the future of enterprise IT, and given their success
of late it is hard to argue against them.
vCloud Director (vCD) is interesting because it avoids the classic
virtualization metaphors ... (more)
True story from the consulting trenches: the operations staff had left hours
ago, shaking their heads and reluctantly leaving the consultants to resolve a
problem with their code. It was well past midnight, in the middle of winter,
in a town many time zones from home. The project was late. Altogether, this
was an awkward situation that you probably know well.
The consultants - falling into that murky classification of not quite
outsider, nor regular employee - worked from hobbled accounts; the security
staff were pros and took their charge seriously. By 2:00 a.m., the group was
Cloud Expo on Ulitzer Technology Review has published an interview with
cryptography pioneer Whitfield Diffie that is worth reading. I had the great
pleasure of presenting to Whit down at the Sun campus. He is a great
scientist and a gentleman.
In this interview, Diffie–who is now a visiting professor at Royal
Holloway, University of London–draws an interesting analogy between cloud
computing and air travel:
“Whitfield Diffie: The effect of the growing dependence on cloud computing
is similar to that of our dependence on public transportation, particularly
air transportation, wh... (more)

So you’ve bought into the idea of service-orientation. Congratulations.
You’ve begun to create services throughout your internal corporate network.
Some of these run on .NET servers; others are Java services; still others are
Ruby-on-Rails—in fact, one day you woke up and discovered you even have a
mainframe service to manage. But the question you face now is this: how can
all of these services be made available to consumers on the Internet? And
more important, how can you do it securely?
Most organizations buffer their contact with the outside world u... (more)
