Today we going to talk about IT Infrastructure, We will talk about the Evolution of IT Infrastructure from the beginning to the present, so it will be around 60 years journey so please sit tight to your chairs this going to be a very long session :) I’m just kidding of course, Actually as this is a very informative topic has a lot of information's so I took the liberty to split it to 4 sessions as the following every session will take around 15-20 Minutes: Evolution of IT Infrastructure Architectures of IT Infrastructure (Traditional, Reference, Converged, Hyper Converged) Virtualization and Cloud Computing (Private cloud, Hyped Cloud, Public Cloud) LIFI vs WIFI
