Service Level Agreement SLA
The part of a contract that says what level of service you are actually promised, and what you get back when it is not delivered.
Also known as service agreement uptime guarantee
Definition
A useful SLA names three things: the target (say 99.9% uptime), how it is measured, and the remedy when it is missed.
An SLA with a target but no measurement method and no remedy is marketing, not a commitment.
Questions about Service Level Agreement
What does 99.9% uptime allow in practice?
About 43 minutes of downtime a month. 99.99% allows about 4 minutes. The extra nine is usually a large step in cost.
