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. Prescribed technical standards and specifications for the FP7 IRMOS service technical interface also examined aspects of translation of ALS terms at the application level into resource-based attributes to bridge the gap between customer expectations and the cloud provider`s 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).  It is not uncommon for an internet service provider (or network service provider) to explicitly state its own ALS on its website.   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.  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. There is an important point to remember: when an ALS agreement is reached, the service provider serves as a service provider to the company; in the case of an OLA, the agreement is reached between two parties within the service provider`s organization. Service level agreements are also defined at different levels: the service received by the customer as a result of the service provided is at the heart of the service level agreement. 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. (z.B. to SLAs superior to the corporate or customer level, which also apply to this agreement) 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. SLAs for cloud services focus on data center features and more recently include network features (see Carrier`s Cloud) to support end-to-end SLAs.  ALS often encompasses many elements, from the definition of services to the termination of the contract.  In order to ensure rigorous compliance with ALS, these agreements are often designed with specific lines of demarcation and the parties concerned must meet regularly to create an open communication forum.
