Service level agreement

Operating procedures and standards for a service contract.

The Explain card

Plain English
A service level agreement (SLA) sets the operating procedures and measurable standards a provider commits to in a service contract: uptime, response times, support hours and what happens when targets are missed.
Example
A company buys hosted LLM inference. The SLA promises a specific availability percentage, a maximum latency per request, notification within a fixed period of any security incident affecting customer data, and service credits if the vendor falls short.
Why it matters
Your AI system is only as reliable and secure as the services beneath it. SLAs are where defenders write in breach notification, data handling and availability guarantees, and where they gain leverage when a vendor fails.
Hook
The promise with a penalty clause.

Word knowledge

How the word is built, where it came from, and what it sits beside in memory.

In a sentence

The hosted inference API is not enabled until the service level agreement lists 99.9 percent monthly uptime and a four-hour incident-notice window.

Why these words
  • service Old French servise, from Latin servitium, slavery supplies the work-done-for-another half, so the bargain is about a supplied function rather than a sold object
  • level Old French livel, from Latin libella, a small balance supplies the degree half, so that work is scored against a mark rather than left open
  • agreement Old French agrement, consent, from Latin ad, to, and gratus, pleasing supplies the head noun, the bargain both sides can cite
Where it came from
Origin
English IT compound, from Old French servise (Latin servitium, slavery, from servus, slave), Old French livel (Latin libella, a small balance), and Old French agrement (consent, from Latin ad, to, and gratus, pleasing)
Entered the language
late 1980s
What changed
Service had meant slavery, then a servant's work, then a public utility. Level had meant a carpenter's instrument, then a horizontal plane, then a degree of quality. Agreement had meant pleasing consent, then a binding bargain. Telecom and IT shops in the late 1980s joined the three to name a bargain that measures uptime and response, and the phrase later became the ordinary label for that measured page in a cloud or model-hosting deal.
How it is spelled
Pattern
c before e is /s/, never /k/
Pattern
-ice nouns from French keep the c
Pattern
-ment from French names a result of a verb
Breaks the pattern
the noun phrase stays three words; a hyphen appears only when service-level modifies another noun
Breaks the pattern
service keeps c as /s/ before e, while the related verb serve drops the c
Breaks the pattern
English level writes e where Old French livel wrote i
