SOA

Solutions based on service-oriented architectures are promising in that they
leverage common services and enable collaborative business processes that cross
organizational boundaries.However, because Web services applications can span
multiple hosts, operating systems, languages, and enterprises, it’s problematic to
measure, control, and manage application availability and performance. In addition
to discussing the relationship of Web services management to traditional
distributed systems management, this survey explores various Web services
management approaches and their underlying architectural concepts.

Interview with Dan Malks, Deepak Alur, & John Crupi of JackBe

http://sys-con.tv/read/239153.htm Live from JavaOne 2006 in San Francisco By: SYS-CON TV Jun. 21, 2006 12:00 PM I liked the fact that Danny Malks mentioned how JackBe is moving towards "lightweight" platform solutions direction with r egards to the convergance of SOA and the client while utilalyzing AJAX technologies. Sounds like a software model that could help other independent software vendors (ISVs), service providers and enterprises deploy their services exposed by their SOA as software as a service (SaaS). In addition, to not only creating meaningfull mashups, but provide a lightweight admin platform to regulate those atomic messages. Interesting listen from the former Sun team who brought us the J2EE bible. Only thing I noticed is that I had to quickly turn down my volume when John Crupi spoke a couple of times. He's so loud.

But Officer BF Johnson didn't think so. He stopped me in my tracks, ordered me to approach him. He then ordered me to hand over my license and called the station to check for any suspicious (Obviously terror-related) activity from my end.
