What is (and what is not) Service Orientation - Part II

2008-02-17T16:13:00Z

In my first post about the subject , I've focused on what service orientation is not . In this second post, I'm writing about what I think service orientation really is: 1) Exposes business processes as services : SO impacts vertically your organization, and may/should change the way you think about and develop software. You will be more and more focused on exposing every process in your organization as a service and not just developing single components. In your analysis/modeling phases, you'll...(read more)

Notes for a 64-bit Architecture Migration Strategy

2008-02-10T13:06:00Z

What does a Software Architect do?

2008-02-09T10:48:00Z

Being a good architect is not an easy task to do. This January, I was in Norway for the Architect's Master Class with Juval Lowy, from IDesign , and one aspect that I've found interesting in what concerns this course organization is the way Juval assigned time to the 3 main areas we discussed: Process (1 day), Technical (2 days) and Design (2 days).
