Scalable
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.
