A Service Level Target (SLO) is a key element of a Service Level Agreement (SLA) between a service provider and a customer. SLOs are agreed as a means of measuring the service provider`s performance and are described as a way to avoid disputes between the two parties on the basis of misunderstandings. In addition, there are three other classifications: customer-based SLAs, services and several steps. 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).  Monitoring of services and reports – This section defines the reporting structure, follow-up intervals and stakeholders involved in the agreement. A multi-stage ALS divides the agreement into different levels specific to a number of customers who use the service. For example, an as-a-service software provider can offer basic services and support to all customers who use a product, but it can also offer different price ranges when purchasing the product, which imposes different levels of service. These different levels of service are included in ALS on several levels. Most service providers provide their service level statistics via an online portal. In this way, customers can check whether the right level of service is being met.
If they can`t find it, the portal also allows customers to see if they are entitled to compensation. The service received by the customer as a result of the service provided is at the heart of the service level agreement. Several definitions of service levels are used in literature and practice. These may differ not only in terms of the size and number of products considered, but also in terms of the time interval to which they are linked. These performance indicators are the main performance indicators (KPIs) of an inventory note, which must be monitored on a regular basis. If performance control of an inventory node is overlooked, the decision maker is not able to optimize processes within a supply chain. The measures should reflect only the factors that make the service provider exercise appropriate control. Measurements should also be easy to collect. In addition, both parties should refuse to choose excessive amounts of measures or measures that produce large amounts of data. However, the intrusiveness of too few metrics can also be a problem, because without you, one could give the impression that the treaty has been violated. When IT outsourcing began in the late 1980s, SLAs developed as a mechanism to resolve these relationships.
Service level agreements set expectations for a service provider`s performance and impose penalties for lack of targets and, in some cases, bonuses for exceeding them. Because outsourcing projects have often been tailored to a particular client, outsourced ALSs have often been designed to drive a particular project. There are three basic types of SLAs: customers, internal and lenders service level agreements. In order to limit the extent of compensation, a service provider can: A Service Level Obligation (SLC) is a broader and more general form of ALS. The two are different because an ALS is two-way and has two teams. On the other hand, an SLC is a one-sided obligation that defines what a team can guarantee to its customers at any time. During Andrieux and. al. define the SLO as “the aspect of the quality of service of the agreement.” From a syntactic point of view, this is an affirmation of the terms of the agreement as well as qualities such as date and time.”  Keller and Ludwig define an SLO more concisely as “the obligation to maintain a certain level of performance for a certain period of time” with respect to the state of the SLA parameters.  Keller and Ludwig further point out that, although service providers are most often the leading unit in the acquisition of SLOS, it is not
