$3.$ Explain both demand and supply$-$side considerations when choosing the hardware platform for an e$-$commerce site. Include a discussion of I$/$O$-$intensive vs$.$ CPU$-$intensive operations and scalability.

Right$-$Sizing Your Hardware Platform

Two strategies in handling customer demands

$-$ Stateless $($ Stateful$)$: The server does not have to maintain an ongoing dedicated interaction with the client

$-$ I$/$O intensive: Input$/$output operations $($e$.$g$.,$ serving webpages$)$do matter more than heavy$-$duty processing power $($e$.$g$.,$ taking orders$)$

$3$ Ways to scale hardware

$-$ Vertically $($scale up$/$down$)$ increase processing power of individual components

$-$ Horizontally $($scale out$/$in$)$ Employ multiple computers to share workload

$-$ Improve processing architecture $-$ Most desirable
