A Service Level Agreement (ALS) is traditionally a contract between an organization and an external service provider. B s, for example, an ISP or an APPLICATION SUPPLIER that imposes certain levels of benefits. But the benefit of an ALS is not limited to external services; SLAs can be used internally to set requirements for everything from support services to internal processes, network performance and availability, performance and application availability. This ALS also uses enumeration marks to clearly identify its services and customer promises. The first point of your ALS should be an overview of the agreement. What service did you promise the other party? Summarize the service it is delivered to and how the success of this service will be measured. When it comes to the level of performance defined in a contract, these levels of service should be specific and measurable. Otherwise, the measurement service will be difficult, as well as the right services to reward and punish the poor service. To this end, an ALS often uses technical terms to quantify service levels such as the average time between errors (MTBF) and average recovery time (MTTR). Once you have set up the services you provide, you are ready to consider your standards, which include concepts such as availability and reliability, as well as response and solution times. You also need to determine what you can offer your customers in the event of a disaster or emergency. In one of these scenarios, will you be able to provide the same operating hours? Other standards you might want to include include response and resolution times. 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. The second step is to identify metrics and define the basic requirements that measure the effectiveness of the reaction time, performance and availability covered by ALS. For each service, the metric used to measure them should be one of the main quantifiable indicators of service quality. The metric should also be realistic. Cloud computing is a fundamental advantage: shared resources, 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. SLAs are common to a company when signing new customers.
However, if there is between sales and marketing services, this agreement specifies marketing objectives such as the number of leads or the revenue pipeline. and distribution activities that follow and support them, such as. B of the committed leads qualified by the marketing team. Here you define the responsibilities of the service provider and the customer. In the next section, the agreement overview should contain four elements: 3. Setting up a system of rewards and penalties for compliance and non-compliance. In the absence of such a system, the service provider is not encouraged to follow ALS. 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.
The main point is to create a new level for the grid, cloud or SOA middleware, capable of creating a trading mechanism between suppliers and consumers to
