Welcome to MOTIFS, where I follow cultural and literary images found in the Bible in an attempt to unearth God's meaning in His pattern of usage.


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. [11] The main point is to create a new level for the SOA network, cloud or 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. 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. [14] [15] The European Commission has presented a summary of the results of various ALS research projects (from specifications to monitoring, management and implementation). [16] The fundamental advantage of cloud computing is the joint use of resources that are supported by the underlying nature of a common infrastructure environment. SLAs therefore extend to the cloud and are offered by service providers as a service-based contract and not as a customer-based agreement. Measuring, monitoring and covering cloud performance is based on the final UX or its ability to consume resources. The disadvantage of cloud computing compared to ALS is the difficulty of determining the cause of service outages due to the complex nature of the environment. It is not uncommon for an internet service provider (or network service provider) to explicitly state its own ALS on its website. [7] [9] 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.

[10] 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. 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. Service level agreements are also defined at different levels: 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. [1] 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. Many SLAs follow the specifications of the Information Technology Infrastructure Library when applied to IT services.
