Question 50

A software engineering team is investigating the latency (response time, in milliseconds) of API requests under two different hosting architectures. Architecture S S\,S uses a serverless computing model, while Architecture H H\,H uses a dedicated virtual host model. The team recorded the latencies of a large number of requests for both architectures and calculated the measures of central tendency shown in Table 1 below.

Table 1: Measures of central tendency for Architecture S S\,S and Architecture H H\,H latencies (ms)

Measure of central tendencyArchitecture S S\,S latency (ms)Architecture H H\,H latency (ms)
Mean120.4105.2
Median98.5105.0
Mode85.0105.0

Using the data in Table 1, explain how the distribution of latencies for Architecture S S\,S differs from the distribution of latencies for Architecture HHH.
