Certified Secure Software Lifecycle Professional Practice

In the context of cloud testing, ensuring optimal performance and scalability of applications is essential. This involves verifying that applications can handle varying loads and perform well under different circumstances, which is crucial in a cloud environment where resources can be dynamically allocated based on demand.

Scalability ensures that as the user base grows or the application needs increase, resources can be added seamlessly to maintain performance. Monitoring performance during load testing can help identify bottlenecks or resource constraints, leading to improvements that enhance user experience and overall application reliability.

While other aspects, like security and resource usage, are important in cloud testing, the primary focus should be on how well the application can perform and adapt to changes in workload, which directly impacts its usability and effectiveness in a production environment.
