Which benefit of the AWS Cloud does this example illustrate?
High availability
Elasticity
Reliability
Global reach
Explanations:
High availability refers to the system’s ability to remain operational and accessible. While Auto Scaling can contribute to high availability by adding instances, it is not the primary benefit illustrated here.
Elasticity is the ability to automatically scale resources up or down based on demand. Amazon EC2 Auto Scaling exemplifies this by adjusting the number of EC2 instances in response to changing workloads.
Reliability pertains to the ability of a system to perform consistently well over time. While Auto Scaling can enhance reliability, the specific action of scaling instances is more closely related to elasticity.
Global reach refers to the ability to deploy applications across multiple geographical regions. Auto Scaling does not directly demonstrate this benefit, as it focuses on resource management within a specific region.
