A FEW HARD-WON LESSONS

PHILIPPE LALANDA

DONE IN COLLABORATION WITH ADA DIACONESCU (PARISTECH)& CATHERINE HAMON (ORANGE LABS)

SOFTWARE ENGINEERING

Development/deployment/administration of pervasive applications is extremely challenging.

Dynamic

Heterogeneous

No administrator

LESSON 1

MODELS ARE COMPLEX AND HARDLY REUSABLE

Autonomic Machine (service oriented)

Deployment Architecture(with variability)

15

LESSON 2

YOU CAN’T GO FROM DESIGN TO EXECUTION

Autonomic Machine (service oriented)

Design Architecture(with variability)

Deployment Architecture(with less variability)

16

LESSON 3

YOU CAN’T COMPOSE ANYTHING

Autonomic Machine (service oriented)

Design Architecture(with variability)

Deployment Architecture(with less variability)

ONE SOLUTION!
