scale changes the design problem space
-
Architecture components must be stateless, replicated, and tolerant of failures of dependent services
-
it can be regarded as tight coupling of the process, logical and physical views in the 4+1 view model
Some preliminary work
-
Lightweight Evaluation and Architecture Prototyping for Big Data (LEAP4BD)
- for decision-making and not real development
-
specify reqs
-
select candidate databases
-
design and implement a prototype
-
evaluate
-
make best choice/decision
