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)

SOA 2 Point Oh No!

Here we go again. While the paint is still wet on this new Web 2.0 stuff, many SOA vendors and large analysts firms are calling their market SOA 2.0. It's one of the silliest things I've heard in a long while, and both the analysts and vendors who use this term should be ashamed of themselves. I get Web 2.0 because the Web is well over 10-years-old and we've been successful in using this pervasive technology and now we're moving to newer and more exciting stuff such as AJAX and RSS thus the new version number. However, we've yet to get large-scale traction with SOA so SOA 2.0 is ... (more)

SOA - Loosely Coupled...What?

With the advent of Web services and SOA, we've been seeking to create architectures and systems that are more loosely coupled. Loosely coupled systems provide many advantages including support for late or dynamically binding to other components while running, and can mediate the difference in the component's structure, security model, protocols, and semantics, thus abstracting volatility. This is in contrast to compile-time or runtime binding, which requires that you bind the components at compile time or runtime (synchronous calls), respectively, and also requires that changes ...

SOA World Focuses on Enterprise-Wide SOA and Cloud Computing Solutions

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 computin...
