A company hosts virtual conferences on Azure. During a keynote speech, the number of active attendees suddenly increases from 1,000 to 50,000 within a few minutes. The company wants the underlying virtual machine instances to automatically add more instances to handle the sudden spike in traffic, and automatically shut down the extra instances when the keynote ends and traffic returns to normal. Which cloud concept describes this ability to dynamically match resources with demand?

Cevabı ve açıklamayı göster

Cevap: Elasticity

Cevap

Elasticity is the capability that allows systems to automatically add or remove resources in response to changing demand patterns.
Elasticity is the correct concept because it represents the cloud's ability to dynamically allocate and deallocate resources automatically to match workload demand. In this scenario, adding VM instances during a traffic surge and shutting them down afterwards precisely maps to elastic behavior.

Adım Adım Çözüm

1
Analyze the requirement of the scenario.
The application needs to scale up automatically to handle a sudden traffic spike and then scale down automatically when demand drops.
Determining that the application must scale both up and down automatically is the key to identifying the correct cloud benefit.
2
Differentiate between scalability and elasticity.
While scalability allows the infrastructure to expand to handle larger workloads, elasticity specifically introduces automated, bi-directional scaling in real-time.
This distinction helps rule out general scalability in favor of the more precise term elasticity.
