Assessing the Performance and Scalability of Cloud-based Software Applications

Vamsi Krishna Thatikonda

Abstract: Cloud computing has revolutionized the IT industry by offering diverse service models such as SaaS, PaaS, and IaaS. As these services become integral to modern businesses, ensuring their performance and scalability is a central concern. Performance relates to a system's responsiveness, evaluated through metrics like response time and throughput. In contrast, scalability assesses a system's ability to adapt to varying user loads, measured through elasticity and load variance. While tools like Apache JMeter and AWS CloudWatch assist in evaluating these dimensions, challenges, like shared resource contention and balancing cost with performance, remain. An illustrative case of Netflix highlights the criticality of consistent performance and scalability testing. In a world dominated by cloud services, achieving a balance between system responsiveness and adaptability is paramount for a seamless user experience.
