It's no secret that cloud computing has been on the minds of a lot of IT
executives. Conference agendas are filled with cloud talk and the Internet is
abuzz with it. As more enterprise IT departments move to the cloud, it begs
the question: How will it affect the traditional role of the CIO. It's fair
to say that there will be changes if the department shifts from a service
provider to utility model with usage-based metering.
This will cause a shift in core tasks from developing applications and user
interfaces and so forth, to a new set of tasks involving defining
service-level agreements, selecting cloud management tools and understanding
customer service. Your role could shift to be more like an independent
business manager running a public service (not unlike Salesforce.com).
Before cloud computing came along, the CIO was involved in strategic
End users like to live in a comfort zone. For many that means their work
applications should resemble the ones they use at home or the ones on their
mobile phones. These programs tend to be simple, consistent and easy to use.
And more and more, end users are demanding the same simplicity they find in
these consumer tools in the tools they use at work. What's an IT pro to do?
One of the basic tenets of private cloud computing is keeping it simple for
end users. That means when they access your resource selection tool on the
Web, users will find it as friendly to use as, say iTunes.... (more)
Not long ago, Forrester analyst James Staten wrote a report with the
compelling title: You're Not Ready for Internal Cloud. What Staten meant, of
course, by the term "internal cloud" is what we have been referring to in
this blog as a private cloud. Whether you're ready or not probably depends a
lot on where you are on the project path.
For those just starting on the private cloud journey, it might be useful to
get the lay of the land and discuss the essential elements of any private
cloud project, and point out areas where my definition diverges from
Staten's, as a recognized e... (more)
One of the advantages that Amazon's AWS has held is the ability to massively
scale its elastic compute cloud (EC2) with nearly hands-free automation.
Amazon, of course, has always been very private about how it does this, but
it seems clear that one of the keys has been their substantially customized
version of the Xen hypervisor which (among other things) likely has
implemented a form of software defined networking (SDN) for a pretty long
while. Capabilities such as AWS CloudFormation, security zones, Elastic
Load Balancer, and others have clearly shown that much of what used ... (more)
Larry Ellison let it be known at the recent Oracle OpenWorld (an ironic name
if I ever heard one) that he saw nothing wrong with companies using just
Oracle solutions across the entire enterprise. Of course, he would think that
given that he runs Oracle. But these days, more often than not, you are going
to find multiple solutions from a variety of vendors, and you need a cloud
solution that is going to support them all.
Once upon a time, a company was an IBM shop with IBM mainframes, software and
support services. On one level, CIOs might have found this single vendor view
