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/service user and the social network resources that expose the interface. These APIs enable many third-party vendors to leverage a social networking resource, but the hidden value will come from the enterprises that can leverage these networks as a new form of business communication. Indeed, I'm fi... (more)

Brokering Web Services... The Next Big Thing?

Web services were created around the notion that it's easier to discover and leverage somebody else's service rather than write your own from scratch. Also, it is much easier to create applications made up of many services, thereby allowing change to occur at a pace faster than anything we've seen in the industry thus far. The idea of Web services was to create a standard interface, programming model, description language, and a directory that would allow this to happen in and among very different systems. Indeed, today you can leverage services across the Internet that are func... (more)

Why 'Enterprise Architects' Are Ineffective with SOA

Architectures are like archaeology; in essence, layers upon layers of systems, applications, databases, and connections, typically built or procured to solve a tactical problem. Many corporations talk a good game and brag about the strategic long-term direction of the enterprise architecture that serves the business. The fact is, tactical needs have trumped strategic direction over the years. Thus, layers upon layers of technology on top of technology are the end result, and an architecture that is inflexible, static, fragile, and thus difficult to change along with the business...

Web-Oriented Architecture (WOA) Gains Momentum

We seem to be riding a new wave…or the combination of two waves really…the Web and SOA. As I've been stating for the past five years: if you want to provide real value to your enterprise, SOA should extend out of the firewall and into the Internet. However, this was not universally accepted by the rank-and-file SOA guys. Generally speaking, most viewed SOA as something that occurred exclusively within the firewall, and extending the reach of their SOA to Internet-based resources was taboo. Thus, the notion of WOA, or Web-Oriented Architecture, is really SOA that us... (more)

Approaching Cloudsizing

You've heard of downsizing and rightsizing, so how about Cloudsizing? As properly defined, Cloudsizing is: The improvement of efficiency and effectiveness of an organization through the selective use of computing resources that are delivered over the Internet Simple but powerful, and fairly obvious, considering all that's been written about Cloud Computing recently. However, what is not obvious is how you approach Cloudsizing, or how you get started. Thus, the purpose of this column/article, and the next three, is to introduce you to both the notion of Cloud Computing and how to d... (more)
