If you've been following me on Twitter, or through my other blogs, you already know that I made it to the SOA World Conference & Expo in San Jose, CA, which was collocated with Cloud Computing Conference & Expo. I did the keynote on Wednesday and then stayed around for some of the sessions and some networking. Overall, SOA World was well attended and the expo hall was full of SOA vendors. The most interesting aspect of this conference was the cloud computing portion and how there was so much crossover with SOA. Many of the SOA players out there are diving into the cloud computing area, and most who are already into cloud computing are traditional software vendors that have moved their stuff into the "as a service" space. I suspect this will continue, considering that Salesforce.com just renamed themselves a cloud computing company, and indeed they are. So, what ar... (more)

The Five Basic Characteristics of SOA

The Gartner Group just listed "9 ways to measure SOA success.” Not to take anything away from Gartner, but theirs is a pretty basic list, if you ask me.  Indeed, these nine measurements are really about any successful architecture, using SOA approaches or not, which is fine. However, I have a few of my own that are more specific to SOA. Here are Gartner's nine: 1. Improved efficiency, particularly with respect to business processes execution. 2. Lower process administrative costs. 3. Higher visibility on existing/running business processes. 4. Reduced number of manual, paper-base... (more)

Cloud Computing and Your Enterprise Architecture and/or SOA

There are a few other issues to consider when looking to leverage cloud computing as a component of your enterprise architecture and/or SOA:  First, cloud computing is not the savior of IT. It's nothing but a way to deploy your enterprise architecture in such as way that has the potential to be more productive and cost effective. In essence, it's a tool, not a way of life. It's not magic, it's not even new, but if approached correctly, could be a path toward efficiency. Second, cloud computing and SOA are different concepts, but they are indeed related. SOA is a pattern of archite... (more)

Cloud Computing & SOA: Getting the Links Straight Between Them

Want to know what gets my blood pressure up? It's when there's both a huge shift in thinking around how we should do computing, namely cloud computing, and at the same time, there's a bunch of information out there that causes confusion. As cloud computing hype spikes to a frenzy, so does the number of less-than-intelligent things that I hear about it and its relationship to SOA. We've got a herd mentality in IT. We're always chasing the next paradigm shift, which seems to come along every five years, claiming that whatever the last paradigm shift was had "failed" and that's why... (more)

AJAX, RIA, SOA & Web 2.0 Mashups - Mash What?

It’s what you don’t see about the emerging Web that has everyone excited these days. Namely, it’s the powerful application programming interfaces, or APIs. APIs are nothing new and have been traditionally cryptic and difficult to use. However, the advent of Web services along with the notion of mashups has changed the way we consider and leverage APIs going forward. What changed? In short, the emergence of API consumers, including service-oriented architecture (SOA), browsers that support rich client features such as AJAX, and the notion and popularity of mashup... (more)
