Open Source and SOA:

A very important architectural movement in the industry.

SOA requires innovation and it requires infrastructure on which it is going to live.

SOA provides a lot of answers to a lot of problems that people have and see for a while.

A risk reduction in terms of extending legacy systems.

SOA is a bit like mentality or fitness.
Using it with Open Source it integrates choice and risk reduction

instead of been locked in to a vendor-specific approach.

The level of IT integration in terms of business processes is always higher with internal providers compared to external providers – that’s the downside of outsourcing.
