Server virtualization provides an immediate reduction in hardware and configuration cost. 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. What if we could apply the benefits of virtualization where we spend 80 percent or more of the IT budget - in the key enterprise software that runs our business and in the extensive development, support and maintenance costs of these applications? Today's leading businesses rely on a mix of distributed technologies and new functionality, such as service-oriented architecture (SOA). Virtualization can improve the quality and time-to-market for these systems. But how can teams virtualize to improve the quality and time-t... (more)

The Cloud Computing Model Won't Catch Up with SOA Anytime Soon

John Michelsen's Blog It will take a while for SaaS in a Cloud Computing model to catch up with SOA. One obstacle for the pure plays in the cloud to join SOA is to recognize and deal with the increased testing and validation of data from even more diverse sources, as well as the governance and validation of all the underlying technologies that contribute to specific business outcomes. I'm on my way to STARwest in Disneyland, CA today, and since it's been a little while since my last software quality-focused conference, I'm particularly interested to see how these testing experts a...

What Is SOA and Service-Oriented Virtualization?

Is SOA Dead, Doomed, or Misnamed?

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... (more)

European SOA: Ahead of the Curve?

I'm in Germany right now, looking forward to a session at ZapThink's Practical SOA in Frankfurt event tomorrow. I'll be joining some peers from companies like T-Mobile, Swisscom, Novartis and SwissLife who are going to be sharing their own SOA success stories. 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, ... (more)
