The production obtained by the customer through the service provided is at the heart of the service level agreement. 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.  Uptime is also a common metric that is often used for data services such as shared hosting, virtual private servers, and dedicated servers. Usual agreements include the percentage of network availability, operating time, number of planned maintenance windows, etc. GIS typically includes many components, from defining services to terminating the contract.  In order to ensure strict compliance with the AGREEMENTS, these agreements are often designed with specific dividing lines and the parties concerned must meet regularly to create an open forum for communication. The rewards and penalties applicable to the supplier are often indicated. Most LTC also leave room for periodic (annual) audits to make changes.
 RP7 IRMOS also looked at aspects of translating application-level SLAs into resource-based attributes to bridge the gap between customer expectations and cloud provider resource management mechanisms.   The European Commission presented a summary of the results of different research projects in the field of ASAs (from specifications to control, management and implementation).  A service level agreement (SLA) is an obligation between a service provider and a customer. Particular aspects of the service – quality, availability, responsibilities – are agreed between the service provider and the service user.  The most common element of an SLA is that services must be provided to the customer as agreed by contract. . . .
