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 projectexplores aspects of multi-level, multi-supplier slas within service-based infrastructure and cloud computing, while another EU-funded project, VISION Cloud, has delivered results in terms of content-based ALS. The problem with this work is to clarify how to build SLM contracts (SLA, OLA and UC) in an ITIL SLM environment depending on the process. There is a need for further clarification of how they are related in the MLS process. Because of the practical orientation of this work, this link becomes closely linked to the process of introducing MLS. Problems should be: Service level agreements may contain many service performance metrics with service level targets. A common case in IT services management is a call center or service desk. Among the metrics commonly accepted in these cases include: This work shows a way to develop a clean SLM contract base for the ITIL SLM process and how SLM contracts between them and with the SLM process. The focus is on the MLS process, taking into account its phased introduction. Thus, after reading this work, one will be able to understand all the links of SLM contracts (SLA, OLA, UC) in the SLM process to understand or create own contracts and SLM for these SLM process statement and basic ground rules.
to verify the completeness of existing contracts and, if necessary, to extend them. 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.” The orientation of the potential of services leads to the need for the service provider, its performance in advance. These performances include, for example, know-how or physical skills (for example. B programming knowledge or the strength and perseverance of employees of a moving department).
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. Since the late 1980s, SLAs have been used by fixed-line operators. Today, ALS is so widespread that large organizations have many different ALSs within the company itself. Two different units in an organization script an ALS, one unit being the customer and another the service provider. This helps maintain the same quality of service between different units of the organization and in several sites within the organization.
