It will:
- introduce SLAs
- agree terminology
- explain how they relate to the other service artefacts - how can a service description feed a SLA e.g.
- quality of service
- access and use - cost of using the service
- to do this we will look at any minimum (regulated) content. The content of SLAs is highly regulated.

Introduction
- A service-level agreement (SLA) is a commitment between a service provider and a client. Particular aspects of the service – quality, availability, responsibilities – are agreed between the service provider and the service user. (wikipedia)
- is a written contract between a service provider and its customer to define the agreed level of quality of that service.
Characteristics:
in order to use a service
consider using a service
contract when using a service
Purpose and usage
A service description can form the starting point for discussions on the SLA. The service description e.g. contains the minimum offered quality of service.

An example of a difference in a SLA over a service description can be found in this discussion on SWIM-SERV-014 Quality of service. At the moment, it sounds like you do not want to commit to a given figure for the availability of the service. It is possible to state "best effort" in the service description. It is then possible to update the service description within the European SWIM Registry if you think an update is needed based on the feedback from operations. SWIM-SERV-014 concerns the quality of service that is offered. The figure is used to inform contract negotiations and the creation of a Service Level Agreement between the provider and consumer. Indeed, it is the figure in the SLA that most interests consumers. Therefore, the service description can stay as "best effort" until you are confident you can provide a more accurate figure. The exact figure can be included in the relevant SLAs. |
