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 we're looking at something new. However, these hype-driven trends are often complementary, and so the real power is in figuring out how known approaches fit with what's new, and not look to replace, but how to build on the foundation. The best case for that scenario has been how SOA benefit... (more)

Where SOA Meets Cloud Computing (Video and Audio)

This is a very compressed audio and video recording of the âWhere SOA Meets Cloud Computingâ webinar, just for the Cloud Computing Podcast subscribers.   Back to audio only with the next posting. ... (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 ...

The Most Popular Web APIs Will Be Social-Oriented and Complex Business-Oriented

As we build services/APIs for use within the enterprise or cloud computing, there seem to be two clear trends for those who are consuming the services/APIs: they want to leverage APIs that drive social networking, such as Twitter and Facebook, and they want to leverage complex, business-oriented, and high-value APIs that they don't want to build themselves. APIs around social networking are easy to define and leverage. They have simplistic data structures and well-defined methods. While they are simplistic to use and understand, they also have huge value for both the API/servi... (more)

SOA to the Rescue in Recession

Many organizations out there don't really have to sell SOA. They understand that hype is the driver, and, in essence, leverage the thousands of articles and books on the topic to sell this architectural pattern. However, in most cases SOA has to be sold in the enterprise. If you're doing SOA right, you'll find that the cost quickly goes well into the millions, so you'll need executive approval for that kind of spending. However, the benefits are there as well, including the core benefit of agility that could save the company many times the cost of building a SOA. Or, at least, tha... (more)
