The Theorem of Scalability

The Theorem of Scalability states that a system's performance can improve proportionally as you increase resources like servers or processing power, up to a certain point. Essentially, if you double the resources, the system should handle twice as much work efficiently. However, beyond a certain scale, adding more resources may yield diminishing returns due to factors like communication overhead or bottlenecks. This concept helps in designing systems that can grow reliably without losing efficiency, ensuring that expanding infrastructure effectively boosts capacity without unnecessary costs or complexity.
