Service Level Agreement (SLA) is that part of a service contract where the level of service is formally defined. In practice, the term SLA is sometimes used incorrectly in the context of contracted delivery time (of the service) or performance. WHAT IS A SERVICE LEVEL AGREEMENT (SLA)? A SLA is a formal negotiated agreement between two parties. It is a contract that exists between customers and their service provider, or between service providers. It records the common understanding about services, priorities, responsibilities, guarantee, etc. with the main purpose to agree on the level of service. For example, it may specify the levels of availability, serviceability, performance, operation or other attributes of the service like billing and even penalties in the case of violation of the SLA. Historically, SLAs have been used since late 80's by fixed line telecom operators as part of their contracts with their corporate customers. More recently, IT departments in larger enterprises have adopted the idea of using service level agreements with their customers, i.e. users in other departments within the same enterprise, to allow for comparing the delivered quality of service with the one promised, and potentially consider the alternative of outsourcing IT services to an external company. A SLA is generally business oriented and doesn't go into much technical detail. Its technical specifications are commonly described through either SLS (Service Level Specification) or SLO (Service Level Objective). SLS is a technical interpretation of SLA. It is therefore intended as an operational guideline for the implementation of the service SLO is a subset of SLS, which contains some service parameters the goals to be achieved by the SLS...
