Zorluk: OrtaHigh Availability, Scalability, and Elasticity

A smart home device manufacturer operates a telemetry platform on Azure to process data from millions of connected smart plugs. During peak hours, the volume of incoming messages fluctuates significantly. The manufacturer configures the Azure platform to dynamically add server instances as the message load increases and remove them as the load decreases. Which cloud concept is primarily illustrated by this automatic adjustment of resources?

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

Cevap

Elasticity
Elasticity represents the ability of a cloud platform to automatically adjust resources (scaling both out and in) in real-time to match the fluctuating demand of an application. In this scenario, dynamically provisioning servers during peak telemetry loads and deprovisioning them when traffic drops perfectly demonstrates elasticity.

Adım Adım Çözüm

1
Analyze the resource management behavior described in the scenario.
The system dynamically adds server instances during high demand and removes them when demand drops, automatically matching capacity to current load.
This shows dynamic resource scaling both upwards and downwards based on active workload.
2
Differentiate between similar cloud concepts such as scalability and elasticity.
While scalability is the general capacity to grow to meet load, elasticity specifically refers to the automatic, bidirectional (scaling out and in) behavior based on fluctuating demand.
Correctly identifying elasticity helps avoid paying for idle resources during low-traffic periods.
