Peter Makholm har allerede nævnt en del fordele ved det, men derudover er
det også nemmere at opgradere. Hver kunde kører i et seperat virtuelt miljø
(en virtuel Linux server), og ved at det er virtuelt, så er det muligt at
tildele en Linux server feks. mere processorkraft, mere RAM, mere diskplads,
etc., blot ved at ændre i det specifikke virtuelle miljø's opsætning. Man
skal ikke til fysisk at indsætte en processor eller RAM-klods mere - det
klares i softwaren, og kan derved klares lynhurtigt (der nævnes 5 minutter i
artiklen).

Det gælder selvfølgeligt også hvis de får en ny kunde, så opretter de blot
et nyt virtuelt miljø og tildeler passende resourcer, i stedet for, evt. at
skulle opstille endnu en server.

Det er lidt smart imnsho :-)
