Which cloud concept is demonstrated by using AWS Compute Optimizer?

Explanations:

AWS Compute Optimizer does not focus on security validation; it primarily helps optimize resource usage and performance rather than ensuring security compliance or validation.

AWS Compute Optimizer is designed for rightsizing, which involves analyzing your current AWS resource usage and providing recommendations to optimize and right-size your resources based on their actual performance and utilization patterns.

While elasticity refers to the ability to scale resources up or down as needed, AWS Compute Optimizer does not directly demonstrate elasticity; it focuses more on optimizing resource configurations rather than managing scaling operations.

Global reach refers to the ability to deploy services and applications across multiple geographical locations. AWS Compute Optimizer does not address this aspect; its purpose is to optimize resource utilization rather than extend global infrastructure.
