Scalability refers to the ability of a system to handle an increasing workload or user base while maintaining acceptable performance levels. It focuses on the system's ability to scale up or scale down in response to increased/decreased demand. & Performance refers to how well a system performs a specific task or operation, often measured in terms of speed, response time, throughput, or latency. \tn
