rate limiting
termnetworkingweb devsecurity
Capping how often something may happen, to protect a system from load it cannot absorb.
Used as containment it buys time without fixing anything, and it moves the problem rather than removing it: whatever was rate limited is still trying, and the queue it forms is now somebody's capacity problem. The retry that masks a slow dependency becomes a thundering herd when the dependency stops entirely.
Also known as: rate limit, throttling
