A Service Level Objective (SLO) is a constraint on the
values of a quality attribute or metric. It is
part of a Class
of Service. In other words, a Class of Service comprises a set of
SLOs expressing a complete service level that is promised to be offered
by the provider's service. [Kritikos et al. 2011] {GEN: Quality
of Service Constraint} |
