Zorluk: KolayHigh Availability, Scalability, and Elasticity

A food delivery service experiences unpredictable spikes in customer order volume during severe weather events. The service utilizes a configuration that automatically provisions additional virtual servers during these spikes and decommissions them once the order volume drops. Which cloud concept does this configuration represent?

  1. A
    High availability
  2. B
    Scalability
  3. ElasticityCevap
  4. D
    Disaster recovery

Cevap

Elasticity
The correct answer is elasticity because the scenario highlights the automatic addition and removal of virtual servers in response to unpredictable traffic spikes. This dynamic adjustment of resource capacity to closely match actual demand is the primary definition of cloud elasticity.

Adım Adım Çözüm

1
Analyze the scenario details: the food delivery service experiences temporary, unpredictable spikes in demand and automatically adds and removes virtual servers to handle this fluctuation.
The scenario describes dynamic, automatic resource scaling (both scaling out and scaling in).
Understanding the key operational requirement helps match it to the correct cloud characteristic.
2
Evaluate the definition of the correct cloud concepts.
Elasticity is defined as the ability of a cloud infrastructure to dynamically provision and release resources automatically based on demand, which matches the behavior described.
Differentiating between elasticity, scalability, and high availability ensures the correct selection.

Anahtar Kavram

Elasticity allows cloud resources to automatically scale out (add resources) or scale in (remove resources) in response to real-time fluctuations in demand, optimizing performance and cost.
