But in focusing merely on the hardware side of virtualization, are we leaving money on the table? While organizations can reduce the number of boxes they need, and save the cost of replicating servers for virtual test beds, these servers are becoming commodities. http://soa.sys-con.com/read/502710.htmhttp://soa.sys-con.com/read/502710.htm Mon, 18 Feb 2008 04:45:00 GMT Lately we've done a lot of research and publishing on how Dev & QA teams can ensure better quality throughout the software development and release lifecycle. But what about the IT Operations guys? It seems we are encountering a disconnect between the Enterprise Architecture and Integration disciplines that are moving to SOA, and the people who need to monitor and maintain these systems in deployment. There are a lot of companies starting to focus on better SOA Governance, which includes the management of business processes and workflows, and the services and applications behind that. Great stuff happening on that side of the IT shop. http://soa.sys-con.com/read/485371.htmhttp://soa.sys-con.com/read/485371.htm Fri, 25 Jan 2008 13:00:00 GMT Why does SOA seem to be moving forward a little faster in Europe than in North America? We've posed these kinds of questions in our surveys and forums, and often it seems that stateside, the term 'SOA' can polarize some IT teams - it's an 'either/or' decision at the architectural level. Talking to our EMEA director, Wilfred, he says part of the reason it seems adoption is high in Europe is that it SOA is often driven by developers working in smaller teams. Service-orientation can be started on a much smaller scale, and tested pragmatically before rollout to the larger organization. So, SOA there doesn't need to be an enterprise-level initiative in all cases, it can be something the company dabbles in before making a full commitment. http://soa.sys-con.com/read/481082.htmhttp://soa.sys-con.com/read/481082.htm Fri, 04 Jan 2008 17:30:00 GMT Server virtualization provides an immediate reduction in hardware and configuration cost.

But this value has yet to extend to SOA, which is by nature much harder to replicate in this fashion. When you have so many distributed and heterogeneous technologies that are often not available for testing and development purposes, something needs to change to bring back that agility we expected from SOA. http://soa.sys-con.com/read/439677.htmhttp://soa.sys-con.com/read/439677.htm Sat, 06 Oct 2007 16:00:00 GMT Many in the media are already calling on the demise of SOA and saying that it's just a passing phase, or it's really just a rebrand of the EAI space, or that it will be segmented only to certain integration-type challenges. We have a bit of a different take. The term SOA will go away over the next several years but it will go the same route that e-commerce applications went. If you think back to the mid-'90s, we started talking about e-commerce as an architecture that was distinct from the then traditional enterprise architecture. However, over the past few years, e-commerce as a term has disappeared because it has become the ubiquitous expectation for how we build applications, or what those applications do (some kind of commerce). It consumed the entire enterprise application space.
