scalable systems

A scalable system is one that can grow and handle increased demand efficiently. Imagine a store that starts with a few employees and limited products; as more customers visit, it adds staff and stock to maintain service quality. Similarly, scalable technology can expand its resources—like adding servers or bandwidth—to support more users or data without losing performance. This flexibility ensures the system remains reliable and responsive, whether it's handling a small group or millions of users, making it essential for businesses expecting growth or fluctuating activity.
