<<It's interesting to think that many of the services we'll leverage within our enterprises won't be created by the enterprise itself, meaning services that are hosted by service providers that we employ on demand. There are many of these examples today, including eBay, Salesforce.com, Amazon.com, and even new startups such as StrikeIron, all looking to make money through the delivery of Web services to those that need them. I call this "Outside-in SOA," and perhaps the most valuable notion of the movement to a more service- oriented world.
For many enterprises this is scary stuff, much like the Internet was scary back in the early 90s. However, as we move to "Web 2.0" we are indeed going to find the value of leveraging application services that we had nothing to do with creating, or incurring the cost or the risk for that matter. Clearly, the days of purchasing or developing software as the default solution are behind us, and we're moving to a model where we can mix and match services on-demand, for any business purpose. This notion will provide us with the business agility and value we're finally looking for from IT. However, the concept of Outside-in SOA needs specific enabling technology, layers of software that are able to manage the interaction with outside services, typically Web services, and the internal systems, including semantic, protocol, and security mediation. To date, most of the work has been concentrated on building a SOA using internal systems, not considering the use of service providers. I'm asserting that the patterns of use are very different, and thus require different approaches and technology.>> You can read this at: "http://www.ebizq.net/blogs/linthicum/archives/2005/11/outside- in_soa.php#comments" Gervas ------------------------ Yahoo!
