SOA Yesterday, Today, and Tomorrow

SOA is buzz word today, it's been referred to as 'dead', it's been sold as  the 'snake oil' to solve all problems.  Fact is it is about architecture and built on years of evolution, not just the principles discovered or established since the term 'SOA' was first put forth to the IT community by the Analysts.    This talk will look back in time and show the evolution from service oriented applications that go back to the 1970's and early mainframes.  However a lot has changed since then, especially in the area of standards, and heterogeneous interoperability.  The session will then discuss SOA from the last five years which has focused on potentially distributed, invokable, 'web' services.  In principle it is the culmination of 25-30 years of efforts.  Finally in the last few years there has been a focus on Event Driven Systems (again a concept that is not new, but the connectivity and ability to deliver large quantites of information in near real-time to hard real-time has driven a need to once again evolve what SOA 'means'.  This evolution and what it might mean to the future of solutions will be the third topic discussed in this session.
