On Architectural Diversity of Dynamic Adaptive Systems
Hui Song, Amal Elgammal, Vivek Nallur, Franck Chauvel, Franck Fleurey, Siobhán Clarke · 2015
We introduce a novel concept of ``architecture diversity'' for adaptive systems and posit that increased diversity has an inverse correlation with adaptation costs. We propose an index to quantify diversity and a static method to estimate the adaptation cost, and conduct an initial experiment on an exemplar cloud-based system which reveals the posited correlation.
