*Tier* & Benchmark Environments     Last updated on           , a full moon day

After year 2000, global data centers are most likely to be in Singapore because of politically, strategically, ... , but a myanmar still cannot classify whether architecture or frequency yet. In common, 2-tier is aka client-server applications, 3-tier is also known as distributed applications, Also see: *tier* in Similarity.htm;

Data tier, Middle tier, Presentation tier, Three tier architecture, ...
