A company wants to add virtual servers to handle unusually high web traffic usage. Which of the following is the most efficient way?

The scenario requires a solution for dynamically scaling server resources to manage fluctuating web traffic. Rapid elasticity is a core characteristic of cloud computing that allows resources to be provisioned and released, often automatically, to scale up or down in response to demand. This is the most efficient method for handling unpredictable traffic spikes, as the company only pays for the additional resources when they are needed, ensuring both performance and cost-effectiveness.

A. Community cloud: This is a cloud deployment model for shared use by specific organizations, not a feature for managing resource allocation based on demand.

B. File synchronization: This is a data management process for keeping files consistent across different locations and is unrelated to scaling server infrastructure.

D. Cloud VDI: This service provides virtual desktops to users and does not address the need to scale web server capacity for handling traffic.

Section 2.1 "The Illusion of Infinite Computing Resources": Discusses elasticity as a key advantage

allowing services to scale up to handle peak loads and scale down when demand decreases.

"Cloud Computing: Definition": Lists "Elasticity" as a key property

describing it as the ability to "add/remove resources (at a fine grain

and fast time scale)."
