  Traditional networking systems, especially the famous 3 tier topology design,
focused more on centralizing the networking systems, and used redundancy as a
protection mechanism against future failures of the system. However, in recent
years, the evolution of decentralization has taken place through several design
techniques. Starting with clients requiring physically separate networks for
critical applications. And then emerged the Spine Leaf topology and the
Software Defined Network solutions. In this research paper, I will first, prove
how decentralization is better than centralization using aspects of probability
theory. Second, I will go further and show how the Spine Leaf and Software
Defined Networks are inherently decentralized, redundant and are better than
the traditional centralized networks.
