The underlying advantage of cloud computing is the sharing of resources supported by the underlying nature of a shared infrastructure environment. Therefore, SLAs cover the entire cloud and are offered by service providers as a service-based agreement, not as a customer-based agreement. Measuring, monitoring, and reporting cloud performance is based on the end-user experience or its ability to consume resources. The disadvantage of cloud computing over SLAs is the difficulty of determining the cause of downtime due to the complex nature of the environment. SLAs typically include many components, from defining services to terminating the contract. This approach makes it possible to maintain the same quality of service between the different units of the organization and also on several sites of the organization. This internal SLA script also makes it possible to compare the quality of service between an internal department and an external service provider.  A Web Service Level Agreement (WSLA) is a standard for monitoring compliance with Web services service level agreements. Authors can specify the performance metrics associated with a Web service application, the desired performance goals, and the actions to take when performance is not achieved. THE 7th IRMOS PC also explored aspects of translating application-level SLA terms into resource-based attributes to bridge the gap between client-side expectations and cloud provider resource management mechanisms. .
