Some comments on this presentation:
There are no more 'green field'. You can go to a company and start an application from scratch, you always need to integrate with something.
There are no 'legacy applications'. A company is always in an evolution process so the todays applications need to integrate with tomorrow's one and the this ones with the past. Applications must be designed for integration.
You can't choose the perfect platform and move everything to it, because in the future the perfect platform will be another.
