Many SLAs follow the specifications of the Information Technology Infrastructure Library when applied to IT services. A service level contract is an agreement between two or more parties, one being the customer and other service providers. It may be a formal or informal legally binding “treaty” (for example. B internal relations within the department). The agreement may include separate organizations or different teams within an organization. Contracts between the service provider and other third parties are often referred to as SLAs (wrongly) – the level of service having been set by the (main) customer, there can be no “agreement” between third parties; these agreements are simply “contracts.” However, operational agreements or olea agreements can be used by internal groups to support ALS. If an aspect of a service has not been agreed with the customer, it is not an “ALS.” For example, you are a customer of a bank and the bank provides you with services. A service level agreement between you and the bank describes the services provided and the levels of service to which they are provided. For example, you can withdraw money at an ATM with the bank, and the transaction does not last more than 10 seconds. This is an example of agreement on service levels and is part of service level management.
Service level management is now primarily responsible for recording service requirements as well as monitoring and reporting of agreed service levels. The SOA course aims to help organizations and individuals understand how the five phases of ITIL`s five lifecycle (service strategy, service design, service transition, operation and continuous service improvement) can add value to organizations and projects. You will also find guides to develop services to meet the needs of businesses and users. A contract is a legally binding agreement between two or more parties. It is important to know for effective management of the ITIL level of service. All negotiated and agreed terms, obligations, obligations and responsibilities of both parties are recorded in a contract. And in the event of a dispute between the parties, if the dispute cannot be resolved, the contract will be the reference before the law or in the courts. Therefore, each item documented in the treaty must be carefully checked and approved by each party. Any clause or condition that cannot be met by any of the parties should not be mentioned in the contract. Service level agreements are also defined at different levels: the third and final type of service level agreement is the multi-level ALS.
In multi-level ALS, aspects of ALS are defined by the client`s organization with a kind of heredition with global definitions relevant to all lower levels. This ALS focuses on the client`s organization. All services and their relationships with subordinate services are used in defining the agree structure for multi-level service levels. The main point is to create a new level for the grid, cloud or SOA 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.
