Zorluk: OrtaHigh Availability, Scalability, and Elasticity

A media streaming company runs its video transcoding pipeline on Azure Virtual Machines. When a large batch of video uploads is received, the system increases the capacity of the active virtual machines by adding more CPU cores and memory to speed up the processing, rather than provisioning additional virtual machines.

Is the following statement true or false: This method of resource adjustment is an example of horizontal scaling (scaling out).

Cevap: Cevap

Cevap

False
The correct answer is false because upgrading the CPU cores and memory of existing virtual machines represents vertical scaling (scaling up). Horizontal scaling (scaling out) would involve deploying and adding more virtual machine instances to the resource pool.

Adım Adım Çözüm

1
Analyze the action taken to adjust cloud resources in the scenario.
The capacity of the active virtual machines is increased by adding more CPU cores and memory to the existing instances, rather than adding new instances.
To classify the type of scaling, we must determine if we are modifying existing resources or adding new resources.
2
Compare the resource adjustment action with the definitions of horizontal and vertical scaling.
Adding resources to an existing instance is defined as vertical scaling (scaling up). Adding new instances is horizontal scaling (scaling out).
This comparison allows us to verify the accuracy of the statement in the question.
3
Determine the truth value of the statement.
Since the scenario describes vertical scaling and the statement claims it is horizontal scaling, the statement is false.
To formulate the final answer based on the classification.
