Define scalability and explain its importance.
What will be an ideal response?
Scalability, sometimes also called extensibility, refers to a system’s ability to expand, change, or downsize to meet the changing needs of a business enterprise. Scalability is especially important in implementing systems that are volume related, such as transaction processing systems. A scalable system is necessary to support a dynamic, growing business. For example, a scalable network could handle anywhere from a few dozen nodes to thousands of nodes, and a scalable DBMS could support the acquisition of an entire new sales division. When investing large amounts of money in a project, management is especially concerned about scalability issues that could affect the system’s life expectancy.
