An online retailer specifies that 99.9 % of incoming HTTP requests must succeed in any given quarter. In Site Reliability Engineering terminology, what is this 99.9 % target called?
Service Level Objective (SLO)
Error budget
Service Level Indicator (SLI)
Service Level Agreement (SLA)
In SRE, an SLI (Service Level Indicator) is the raw measurement, such as the actual percentage of successful requests. An SLO (Service Level Objective) is the desired target or threshold for that measurement-in this case, 99.9 % success per quarter. An SLA is a contractual commitment usually defined between a provider and its customers, and an error budget is the allowable margin of failure derived from the SLO (100 % − SLO). Therefore, the 99.9 % target described is an SLO.
