Service-Level Agreement
A formal commitment from Microsoft on the expected uptime and connectivity of a service.
A Service-Level Agreement (SLA) is a formal commitment in which Microsoft guarantees a minimum uptime and connectivity percentage for an Azure service, plus the service credits customers receive if that threshold is missed. Different services carry different SLA percentages, and free-tier resources typically carry no SLA at all. The key exam nuance is composite SLA calculation: when an application depends on two or more services, you multiply their individual percentages together, which always yields a number lower than either alone. Adding redundancy through availability zones or paired regions can raise the effective uptime guarantee above a single instance.
