Admission Control

Admission control is a strategy used to manage access to resources, ensuring that systems or services operate efficiently. It involves setting limits on how many users can access a service or application at any one time. This helps prevent system overload, ensuring that performance remains stable and that users have a smooth experience. For instance, a website might limit the number of users who can log in simultaneously to avoid crashing. Essentially, admission control balances demand with available capacity, maintaining service quality while managing peak usage times.
