This podcast is in the format of a roundtable discussion with a really good group of knowledgeable people such as Steve Garone, Tony Baer, Joe McKendrick, Neil Macehiter, Jim Kobielus and Dana Gardner. 

The podcast starts off with a debate between the SOA stack versus best of breed implementations, but they finally start talking about other subjects shortly after. 

Here is an excerpt:

We also have to remember that this evolution of SOA is not happening in a vacuum. There are other major IT trends and business trends of worth. Many of them are focused on trying to reduce the cost of ongoing maintenance and support somewhere between 60 and 80 percent of total IT costs, and maybe more, to free up discretionary spending and to reduce the total spending for IT in many organizations. The trends often involved include data center consolidation, moving toward a more standardized approach for underlying hardware, embracing virtualization/grid/utility principles, and so on. Perhaps we have to recognize that even as SOA moves on its own sort of trajectory, organizations are going to be consolidating and looking for commonality of services, and improved support and maintenance types of features throughout their infrastructure.
