Performance Metrics Scalability Ability of a system to grow and manage increased traffic. Increased volume of data or requests. Our goal is we want to achieve this growth without a lose in performance. Bad system design could result in a bottleneck on the number of users or traffic our application can handle, or could result in exponentially increasing cost to server a small increased traffic. Reliability Probability a system will fail during a period of time....
