Ultimately, the author encourages demonstrating practical implementations rather than just discussing theoretical concepts.
Tutorial introduction to OSGi
- 1. What’s Up with Modularity ?!
- 3. Observations Extremely agile (first mover advantage) Architecture (and code base) should be able to cope with change Trend Applications tend to grow bigger and more complex Agile development and refactoring have become more common
- 4. Modularity is the answer
- 5. What we lear ned about OO design in university : Prevent (tight) coupling Promote cohesion cohesion coupling
- 7. What do we need design consequences High-level enterprise APIs Architectural focus on modularity Runtime dynamic module framework Right now, OSGi is the only option let’s not reinvent the wheel for modularity?
- 8. Stop talking… and show me code!
