Well-developed and well-implemented service level agreements can benefit customers, users and suppliers, including internal IT. These benefits will be all the more evident if the design is accurate, the implementation planned, the active use and the continuous improvement. Here are some of the advantages of the SSA: the it-service service contract is the contract by which a person or company (the provider) is obliged to provide an IT service to another person or company (to customers) independently and for remuneration. This agreement often supplements the license terms and the use of software. Many SLAs track to the Information Technology Infrastructure Library specifications when applied to IT Services. The main point is to build a new layer upon the grid, cloud, or SOA middleware able to create a negotiation mechanism between the providers and consumers of services. An example is the EU-funded Framework 7 research project, SLA@SOI, which is researching aspects of multi-level, multi-fournisseurs SLAs within service-oriented infrastructure and cloud computing, while another EU-funded project, VISION Cloud, has provided results with respect to content-oriented SLAs. You are a publisher and you have just launched your software on the market? Have you thought about correctly defining your contractual obligations in terms of availability and continuity of your services vis-à-vis your customers? Similarly, indicators and clauses delineating the extent of IT service provider intervention can sometimes be unclear and difficult for the uninitiated to interpret. For example, the availability of the service is often represented by a percentage, a multiple between 99% and 100%: «I guarantee that the software will be available 99.1% of the month». The SLA – or the Service Level Agreement – is a document intended to define and measure the commitments made by the provider with regard to the level of service. Alsd content varies depending on the type of software used or the expected IT services. However, it is generally recommended to include in particular the following information: 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.  The most common component of an SLA is that the services should be provided to the customer as agreed upon in the contract. For example, INTERNET service providers and telecommunications companies will typically include service level agreements in the terms of their contracts with customers in order to define the level(s) of the service sold in plain language. . . .
