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, that's the idea. How do you sell SOA? Let's look at a few key concepts, including: Shining a light on existing limitations Creating the business case Creating the execution plan Delivering the goods Shining a light on existing limitations refers to the process of admitting how bad things are.

"Many SOA Vendors Can't Explain Their Own Product," Claims David Linthicum

Last month I wrote about vendor-driven architectures (VDA), and I had a few vendors ask me to look on the other side of the fence. In essence, to consider how vendors can better address the needs of the customer, considering the new drivers with SOA. Truth be told, I can't believe the unsophisticated approaches many vendors have when selling their product. Indeed, I'm taken aback weekly by a vendor pitch that just does not flatter their technology, perhaps even making them take a few steps back in my book, and perhaps in the opinions of their customers.

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)
