Explanation: Scalable applications are able to meet increased demand with consistent
results in acceptable time windows.
When a system is scalable, it scales horizontally or vertically to manage increases in load
while maintaining consistent performance. In basic terms, horizontal scaling adds more
machines of the same size (processor, memory, bandwidth) while vertical scaling increases
the size of the existing machines.
