The Service Level Agreement (or SLA) is part of a contract that defines exactly what services will provide the service provider and the level or the standard needed for the service.
Service providers need SLA to help them manage customer expectations and define the severity and circumstances in which they are not responsible for blackout or performance issues. Customers can also benefit from SLA because the contract explains the characteristics of service performance – which can be compared with other vendor SLAS – and determine the means to load service problems.
