A new version of an e-commerce application was deployed using a standard template configuration of 4 vCPU and 8GB of RAM. The administrator has configured the application to automatically add 4 GB…

Integration testing verifies that different application components or services communicate and work together correctly, not that performance thresholds trigger scaling actions.

Load testing applies a continuous, sustained workload to an application to drive resource utilization to a target level and verify that scaling or threshold-based behaviors activate as configured. In this scenario, the administrator needs to confirm that sustained RAM usage above 80% over the defined period triggers the addition of 4 GB of RAM, which is exactly what load testing is designed to validate. Without load testing, there is no reliable way to confirm the auto-scaling configuration behaves correctly under real demand conditions.

Penetration testing is a security assessment technique used to identify vulnerabilities, not a method for validating resource scaling or performance thresholds.

Automation testing refers to using automated scripts to execute test cases efficiently, but it is not a specific testing type that validates resource utilization and scaling behavior.
