Service Level Agreement

(abbreviated to SLA) is an agreement between the customer and service provider regarding mutual rights and obligations. In particular, an SLA specifies which requirements a service must fulfill in terms of availability, reliability, response times, etc. and which costs may be charged. Performance fulfillment is often measured using key performance indicators. An SLA usually leads to the application of bonus-malus systems.
