In his InfoWorld blog, Dave Linthicum cites (yet another) survey on CIO plans (or not) for cloud computing.  No surprise, the survey reported that “security concerns were the biggest barriers to widespread consumption of cloud services.

Dave believes the true problem is one of understanding:

“I’m not sure that the rapidly emerging cloud computing universe has done a good enough job in leading existing enterprise IT shops to cloud computing. Everyone is talking about the "why" — leaving out the "how" and the "what."

CIOs are a bit wary around another paradigm shift. You have to admit that we’ve had one or two over the last 20 years that have not gone anywhere, and the reality for several others never measured up to the hype. CIOs are measured by their ability to make the trains run on time within their own spheres of control, not about how innovative they can get with emerging and overhyped technology.”

Dave continues with ever-practical advice on how to “enlighten the rank-and-file CIO out there around the benefits of cloud computing”:

“First, look at cloud computing for what it really is: architectural options to make existing IT systems more effective. You drive this from the inside out, not the outside in. There is no "big switch" or "huge shift." Instead, you solve small, well-defined problems with the best solution. In some instances, cloud computing is an instance of a solution and not always the solution.

Second, do a prototype. Cloud computing means not having to buy hardware and software, so taking cloud computing for a test-drive is inexpensive and a great learning experience.

Finally, and most important, understand that cloud computing is an evolutionary — not a revolutionary — path for most organizations. The use of cloud computing will be around a systemic change that takes a long period of time for most IT organizations. That’s something a CIO can responsibly handle.”

Quickly discovering I wasn’t the only enterprise architect, services architecture type interested in cloud computing, I invited David Linthicum, SOA expert, enterprise architecture advocate, blogger, founder of Blue Mountain Labs, and all around nice guy, to speak at the March SOA Consortium meeting on the Intersections of SOA and Cloud Computing. 

The podcast of Dave’s talk is now available from the SOA Consortium.  What follows is the “blurb” on the podcast that I posted at SOA Consortium Insights.  If like me, you are getting intentional in your cloud watching, I highly recommend this podcast.

“Linthicum opened by sharing the distinctions and connections between SOA and cloud computing. SOA is something you do, an architectural pattern. Cloud computing is an architectural option.

Dave is talking about Winning with Cloud Computing Step-by-Step.  The presentation is up on slideshare.  Dave’s presentation is based on work from a forthcoming book. [Link added 10.27.2009]

The basic idea is you can extend your SOA to the cloud, utilizing external resources, either business or informational services, or infrastructure resources.

Cloud & SOA lets us mix an enterprise architecture cocktail.  [works for me]

You can’t replace enterprise architecture with cloud computing.  You can’t replace SOA with cloud computing.  You always need an architectural strategy.  Adding cloud computing allows you to cash-in on SOA.  more >>

As promised, here are some links that should be of interest to enterprise architects who are (or need to be) cloud watching.  And yes, I realize I’ve mixed in a leadership interview with Xerox’s Anne Mulcahy, but once you read the others, you’ll be appreciative of a leader who gets that dealing with ambiguity is a sought after, and well compensated, skill.

What SOA Can Learn from Cloud Computing and Vice Versa | David Linthicum

SOA can learn from cloud computing Service Design & Expandability. Cloud from SOA: Governance & Architecture driven. Service Design: "Those who deploy services in the cloud, such as Amazon, TheWebService, Force.com, have done a pretty good job with service design. You really have to do a good job in order to rent the darn things out. Many SOA projects have a tendency to build services that are too course-grained, too fine-grained, or just not at all well designed. The reality is that services that are not well defined and designed won’t sell well when delivered on-demand, and thus those who provide services out of the cloud – which are most major cloud computing providers – have to spend a lot of time on the design of the services, including usability and durability. I urge those who build services within their SOA, no matter the enabling technology and standards involved, look at what’s out there for rent as good examples of how services should be designed, developed, and deployed."

IBM, Sun and cloud computing | Gathering clouds | The Economist

"The economic crisis has pummelled Sun, which never really recovered from the dotcom bust. As its share price plumbed new lows, IBM’s remained relatively unscathed—a reflection of its business, which has been protected by the computer giant’s global scope and the fact that it makes most of its money from software and services.  more >>

Dave Linthicum is up now.  He says his purpose is to be a curmudgeon.  So, we’ll see how that goes.  He’s talking about the relationships between enterprise architecture, service-oriented architecture and cloud computing.

He warns us that this presentation is relevant for this instance in time.  In six months, this will change because cloud computing is rapidly evolving.

SOA & Cloud Computing

"The trick is to determine which services, information, and processes are good candidates to reside in the clouds, as well as which cloud services should be abstracted within the existing or emerging SOA."
