Zorluk: OrtaHigh Availability, Scalability, and Elasticity

Is the following statement true or false?

An e-commerce company experiences a sudden, temporary spike in web traffic. To handle the load, the IT administrator manually increases the size of their Azure Virtual Machine by upgrading its CPU and RAM. This manual reconfiguration of a single resource is an example of implementing cloud elasticity.

Cevap: Cevap

Cevap

False
The statement is false because elasticity refers to the cloud's ability to automatically and dynamically allocate or de-allocate resources in response to changing demand. In contrast, manually upgrading the CPU and RAM of a single virtual machine is an example of manual vertical scaling (scalability).

Adım Adım Çözüm

1
Analyze the scenario details: the resource adjustment is performed manually by an IT administrator, and it involves upgrading the CPU and RAM of a single Virtual Machine.
Identified that the action is a manual upgrade of a single resource (vertical scaling).
To distinguish between scalability and elasticity, we must determine if the resource changes are manual or automatic, and if they involve changing the size (vertical) or count (horizontal) of resources.
2
Recall the definitions of cloud scalability and elasticity: scalability is the ability to handle increased load by adding resources (manually or automatically, horizontally or vertically), while elasticity is the ability to dynamically and automatically scale resources to match demand.
Confirmed that manual resizing of a single instance is vertical scalability, not elasticity.
Elasticity requires automatic, dynamic scaling out and scaling in to match demand fluctuations without manual intervention.
