Each SLA management strategy takes into account two well-differentiated phases: contract negotiation and real-time execution monitoring. Therefore, the SLA administration includes the definition of the SLA contract: the basic scheme with the QoS parameters; THE AES negotiations; SLA surveillance; detection of ALS lesions and the application of ALS, as directed. 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. For example, high-end or standard services, incidence or requirement services, or any other distinction between services. Any professional wishing to develop a career in IT services management should consider an ITIL v4 certification course.
After certification at the ITIL Foundation, you can help a business organization execute best IT services management practices and use IT as a tool for growth or change. A Service Level Contract (SLA) is a contract between a service provider and its customers that documents the services provided by the provider and sets out the service standards that the provider is required to meet. 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. This agreement is tailored to the needs of the end-user company.
