Difficulty: EasyHigh Availability, Scalability, and Elasticity

A logistics company configures its package tracking application to automatically allocate more virtual machines during high-traffic holiday seasons and deallocate them when demand drops. Is this behavior an example of cloud elasticity?

Answer: Answer

Answer

Yes, the described behavior is an example of cloud elasticity.
Elasticity is the cloud capability where resources are automatically added or removed to match demand. The logistics application's behavior of automatically allocating virtual machines during holiday spikes and deallocating them afterwards meets this definition.

Step-by-Step Solution

1
Identify the resource management behavior described in the scenario.
The application automatically scales resources up (allocating virtual machines) during peak times and scales them down (deallocating virtual machines) when demand declines.
Understanding the dynamic, automatic, and bidirectional nature of the resource adjustments is key to identifying the correct cloud concept.
2
Match the behavior to the definition of cloud elasticity.
Elasticity is defined as the capability of a system to automatically adapt resource capacity to workload fluctuations.
Since the resource adjustments are automatic and match the demand pattern, this perfectly aligns with cloud elasticity.

Key Concept

Cloud elasticity refers to the ability to automatically scale resources dynamically (both out and in) to match demand.
