Editing Work Amplification (section)

== Software ==

In software, a host of techniques exist to reduce the scope of the problem:

* caching - cut subsequent response costs at the price of freshness
* debouncing - assist with accidental request replication
* rate-limiting - control requests to match response costs
* request aggregation - set `n` request cost to same as 1 request cost

These are all necessary because otherwise it's trivial for someone to intentionally or accidentally result in denial of service. Modern designs usually distribute work-execution from work-determination which allows for many of these things to not be a problem. You may receive a thousand requests, but you only ever do the expensive thing every minute or so which allows you to just aggregate them.
