Scalability is defined as a system's ability to handle increased loads by adding resources without sacrificing performance [], and importantly, doing so cost-effectively []. This necessitates understanding how to coordinate work across these added resources and ensuring that the overhead doesn't negate performance gains []. Objectively comparing systems is more valuable than simple labels, often visualized through response time versus demand curves, where a more scalable system shows a less steep incline []. The goal is to push the system's performance degradation point, the "knee" in the curve, as far to the right as possible [].
