Service level agreements are also defined at different levels: you enter into service-level SLA or “Service-based SLA” when multiple parties use a service or product supplier. A Service Level Contract (SLA) is an obligation between a service provider and a customer. Specific aspects of the service – quality, availability, responsibilities – are agreed between the service provider and the service user. [1] The most common component of ALS is that services are provided to the client in accordance with the contract. For example, internet service providers and telecommunications companies will generally include service level agreements under the terms of their contracts with customers to define service levels of service level sold in plain language. In this case, ALS generally has a medium-time technical definition between errors (MTBF), average repair time or average recovery time (MTTR); Identifying the party responsible for reporting errors or paying royalties; Responsibility for different data rates throughput; Jitter; or similar measurable details. The Service Level Agreement (SLA) or the German Service Quality Agreement (DGV) refers to a contract between an IT service provider (Provider) that regulates recurring IT services, response time and processing speed. Quality of service, which describes the agreed quality of service, is an important element in this regard. A web service level agreement (WSLA) is a standard for monitoring compliance with web services according to the service level agreement. It allows authors to indicate performance metrics assigned to a web application, desired performance goals, and actions to perform if performance is not achieved.

The service received by the customer as a result of the service provided is at the heart of the service level agreement. FP7 IRMOS also examined aspects of translation of ALS terms at the application level into resource-based attributes to bridge the gap between customer expectations and cloud provider resource management mechanisms. [14] [15] The European Commission has presented a summary of the results of various ALS research projects (from specifications to monitoring, management and implementation). [16] The main point is to create a new level for the SOA network, cloud or middleware, capable of creating a trading mechanism between service providers and consumers. For example, the EU-funded Framework SLA@SOI 7 research project[12]explores aspects of multi-level, multi-supplier slas within service-based infrastructure and cloud computing, while another EU-funded project, VISION Cloud[13], has delivered results in terms of content-based ALS. It is not uncommon for an internet service provider (or network service provider) to explicitly state its own ALS on its website. [7] [9] The U.S. Telecommunications Act of 1996 does not specifically require companies to have ALS, but it does provide a framework for companies to do so in Sections 251 and 252. [10] Section 252 (c) (1) (“Duty to Negotiate”) obliges z.B. established local exchange operators (CIDs) to negotiate in good faith matters such as the sale of dentes` and access to whistleblowing channels. Service level agreements can contain many service performance metrics with corresponding service level targets.

A common case in IT services management is a call center or service desk. Among the metrics generally accepted in these cases are: The goal of an ALS is to maintain the quality of a service in measurable indicators. This level of service must be achieved by the contractor in his activities for the client and, depending on the type of contract, he must maintain it for a longer period of time. A service level contract is an agreement between two or more parties, one being the customer and other service providers.
