Since the late 1980s, SLAs have been used by fixed telecommunications operators. Today, SLAs are so prevalent that large organizations have many different SLAs in the company itself. Two different units in an organization write an SLA, one being the customer and the other the service provider. This approach helps maintain the same quality of service across different units of the organization and across multiple locations in the organization. This internal SLA scripting also makes it possible to compare the quality of service between an internal department and an external service provider. [4] In order to limit the amount of compensation, a service provider: a service level agreement (SLA) defines the level of service that a customer expects from a provider and defines the metrics on the basis of which that service is measured, as well as corrective actions or penalties, if any, if the agreed service levels are not met. The purpose of this SLA is to clarify the requirements of the SaaS service as defined here with regard to: by defining the requirements, everyone knows what the volume of work is, it cannot be changed at the last minute and the provider can achieve the objectives more easily – the objectives are difficult to achieve if you do not know: What they are. It is not uncommon for an Internet backbone service provider (or network service provider) to explicitly display its own SLA on its website. [7] [8] [9] The U.S.
