This meant that the user interface software UI , the program itself, and the database would be running on the same platform operating system and computer. Thus, Tier 2 architecture solutions started to be utilized. As the internet became popular in the s, it brought with it a revolution in terms of a user interface which was more performant and capable, but necessitated a specific web server. This widely empowered the proliferation of Tier 3 architecture in which the UI component was separated from the core computing and the database. N-tier or multi-tier architecture refers to software that has its several layers rendered by distinct IT environments tiers under a client-server logic. A layer is a logic component within a software suite that accomplishes a given functionality, whereas a tier is the logical and hardware platform where such layer runs.
