Capacity Planning
Performance
// Definition
Forecasting the infrastructure needed to handle expected load — CPU, memory, database connections, network. Performance test results feed the model that decides how much hardware to provision.

Load Testing
Verifying system behaviour under expected production load. Confirms the application meets performance targets at typical concurrent-user counts before release.
Throughput
The amount of work completed per unit of time — requests per second, transactions per second. Higher is better.
Concurrent Users
The number of users actively interacting with the system at the same moment. A primary input to load and stress test design.
