The I Ching is one of the most precious cultural heritages of the Chinese nation.It contains ancient people's understanding

philosophy and dialectics of the universe and human society

which represents the philosophical thinking of ancestor about universe.We study the hierarchy design in computer architecture from the perspective of the I Ching and classify layers of the hierarchical architecture into yin and yang property

which helps us better understand the essence of hierarchy design and brings design models and theories.In order to give evaluations of the hierarchical model for architecture design

we establish a theory of hierarchical unity of opposites and combination of hardness with softness

which can promote the coordinated development between hierarchical components.By discussing the hierarchical connection relationship of trigrams and the hierarchical model of Six Yao

this paper expands the development and evolution of the I Ching hierarchical model.It also clarifies the approach and reasoning of hierarchical model design by the examples of SDN hierarchical model and cloud computing hierarchical model.Finally

this paper makes a conclusion and proposes the research plans for future works.
