Scalability refers to a system's ability to handle increased demands by adding resources without requiring fundamental redesign. A scalable website can serve more users by adding servers. A scalable process can handle more transactions by adding staff without changing procedures. For government digital services, scalability ensures systems can accommodate growth in users, data, and transactions. Poor scalability leads to system slowdowns or failures during high demand. Cloud computing improves scalability by allowing resources to be added on demand. When evaluating technology solutions, municipalities consider whether systems can scale as the community grows or service demands increase.
