tech to try and increase resource utilization. Often sought out for its dedicated resources.

Advantages of cloud computing - correct answer✔✔Capital expense traded for variable ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




expense (pay for what you use). ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||

, Benefit from massive economies of scale (so many users in the cloud translates into lower||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




prices for all). ||\\//|| ||\\//|| ||\\//||

||\\//|| Increased speed and agility (everything is just a click away). ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




Stop spending money on running and maintaining data centers (focus on money making
||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//|| ||\\//||




endeavors). ||\\//||
