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.   The European Commission has presented a summary of the results of various ALS research projects (from specifications to monitoring, management and implementation).  Service level agreements may 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 measures agreed in these cases are: 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.” 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.  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. Quiz`s estas sean las siglas mes desconocidas para la mayora. El SLA (Service Level Agreement o Acuerdo de Nivel de Servicio, in castellano) es un acuerdo marcado entre dos partes con respecto a servicio determinado. In otras palabras, se trata de un contrato donde se describe el nivel de servicio que un cliente espera de su proveedor. Los SLA no son solo un acuerdo por escrito de unos determinados servicios. También se establecen unos determinados levelles de calidad. Uptime is also a common metric that is often used for data services such as shared hosting, virtual private servers and dedicated servers. General agreements include network availability percentage, operating time, number of planned maintenance windows, etc.
Because applications are moved from dedicated hardware to the cloud, they must reach the same level of service, or even more sophisticated than conventional installations.
