\u201cSLIs drive SLOs which in turn inform the SLA\u201d<\/em>\u00a0<\/p> SLOs are specific sets of targets that define the objectives that the service provider has to meet. SLO parameters generally include availability, throughput, reliability, etc. SRE believes that the core requirement of success is availability. In the context of SRE, availability can be defined as a system being able to perform the required function expected from it at a point in time. While enacting SRE within an organization, we tend to set a numerical function to measure availability. It is known as the availability service level objective of the system. The other objective is the reliability of the systems. If the reliability of a service increases, it becomes more expensive to operate. We state the lowest level of reliability that you can obtain from each service as our SLO. This is the benchmark of reliability that allows your stakeholders to decide whether your service needs should be made more or less reliable\u00a0\u00a0<\/p> The contract agreement between the service provider and the user documents the list of services and the service standards that need to be maintained by the service provider.
