It’s important to remember that there is a huge resource being created on the Web these days in terms of both services and content. This includes access to SaaS applications (that are better than their enterprise-bound counterparts), service marketplaces (such as StrikeIron), and even mash-able applications that you can mix and match with other Web 2.0 applications / APIs / services or enterprise applications / services to quickly solve business problems. However, having such a resource available for the price of a broad-band connection does not mean you'll be able to leverage it properly. Indeed, it's going to take some time before your enterprise is prepared to leverage mashups beyond the browser. The best approach to SOA / mashup synergy is to design and deploy the first-generation SOA with the mashups in mind. In other words, make your enterprises systems... (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)

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)

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)

Leveraging Web Services for Application Integration

Web services holds the promise of moving beyond the simple exchange of information - the dominating mechanism for application integration today - to the concept of accessing application services that are encapsulated within old and new applications. This means organizations can not only move information from application to application, but they also can create composite applications, leveraging any number of back-end application services found in any number of applications, local or remote. Key to this concept is figuring out how Web services fit into the existing application int... (more)
