An SLA is a contractual agreement between a service provider and a customer that defines the expected performance and availability targets for a service. It defines specific key figures, such as response time, availability and downtimes, as well as the consequences of non-compliance.

Availability is often calculated as a percentage of the time a service is available over a certain period of time. For example, if an SLA guarantees an availability of 99.9%, this means that the service may only be unavailable for a maximum of 8.76 hours in a year.
