Scalability is the ability to grow. Elasticity is automatic scale out and back in with demand.

Scalability

Scalability refers to a system's ability to handle an increasing amount of work or its potential to be enlarged to accommodate that growth. It involves adjusting resources, such as processing power, memory, or storage, to meet fluctuating demands without compromising.

Scalability is a system's capacity to grow and handle increased workload, crucial for performance and efficiency.
