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. 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. 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.
This internal ALS script also compares the quality of service between an internal service and an external service provider.  Compensation for the downtime described in this section 4.4 replaces all other remedies in the event of non-compliance with Wolters Kluwer`s agreed availability and the client is not entitled to further compensation or corrective action in the event of such downtime. In order to seek redress under this section 4, the customer is required to notify Wolters Kluwer within 15 days of non-compliance with the current level of service. Wolters Kluwer reports on the level of service for the last reference period to the customer`s request. 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).  5.3 Technical contact is the customer`s primary point of contact for the communication of the online application service and requests related to incidents with Wolters Kluwer.
