This post picks up on two ideas in my last post. The first idea is that IT will have significant change, in part, from the adoption of Cloud Computing. Take a look at IT Departments Won’t Exist in Five Years at Computerworld.com. It states that: Consumerization of IT and self-service trends will lead to a [...]

Last April, Jason Bloomberg of ZapThink issued a ZapFlash titled Cloud Computing: Rethinking Control of IT. I thought it would be useful to organize his arguments into a Force Field Analysis as described in Web Services, Service-Oriented Architectures, and Cloud Computing. The following analysis also includes information from two other ZapFlash entries that Jason referenced [...]

After last week’s posting, I thought I should say more about incremental SOA analysis. The following is from Chapter 10 in Web Services, Service-Oriented Architectures, and Cloud Computing. Service-oriented architecture (SOA) projects are no different from other IT projects in that larger projects tend to fail and issues regarding change can scuttle projects. This chapter [...]

Computerworld had an article last January that discussed American Airlines’ approach to using Web Services and multiple enterprise service buses (ESBs) as part of their service-oriented architecture (SOA). The authors emphasized a change from build vs. buy and from using mainframes. That, however, is not the part I found interesting. (Also, several comments to the [...]

After a very long gap, I’m resuming postings. Going forward, this blog will be a source of information about software design with an emphasis on service-oriented architecture (SOA) and Cloud Computing. Using my background and experience, my intent is to provide useful information and thought on software design rather than just add to the general [...]

Container-Managed Persistence (CMP) occurs when the entity object delegates persistence
services. With CMP, the EJB container transparently and implicitly manages the persistent state. The enterprise bean developer does not need to code any database access functions within the enterprise bean class methods.

The Savvy Manager's Guide
Douglas K Barry has prepared the material on this site. He is also the author of a book that explains Web Services, service-oriented architecture, and Cloud Computing in an easy-to-understand, non-technical manner.
Web Services, Service-Oriented Architectures, and Cloud Computing: The Savvy Manager's Guide (Second Edition)
by Douglas K Barry with David Dick
One of the toughest jobs for managers today is keeping up with the rapid changes in technology. An important change in technology is that the future of software will involve service-oriented architectures with some form of cloud computing. More and more services are available on the Internet. Nearly every day, we can discover new opportunities to connect these services together to create service-oriented architectures (SOAs). These SOAs will require less custom software in organizations, but will likely demand more creativity in the selection and assembly of services. This is a natural evolution of software technology and will be explained in this book.
This is a non-technical book on a technical subject. It assumes no prior knowledge of the technology. It is written with a high-level view at the beginning of the book. As the book progresses, technical details are introduced and explained. You can stop reading at any point once you have enough understanding for your use.
"Web Services, Service-Oriented Architectures, and Cloud Computing by Douglas Barry provides easy-to-follow guidance around the proper use of web services, how they exist within SOA, and how the emerging use of cloud computing correctly fits into the mix. This is something that most in this industry can neither define nor implement, and getting it right the first time is critical to success. If you're looking to understand the true nature of web services, SOA, and cloud computing—including the underlying details—then you should begin by reading this book."
