Exclusions — Specific services that are not available should also be clearly defined to avoid confusion and to make room for other parties` assumptions. The administration of ALS does not stop as soon as we provide the service. It is important to analyze customer satisfaction, for example through regular surveys. It is important to ask them for their opinion, to know the effectiveness of our agreement management and, if necessary, to adapt improvements. 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. Service level agreements are also defined at different levels: an agreement at the level of after-sales service is reached between the supplier and an external customer. There is an internal ALS between the supplier and its internal customer – it can be an organization, a department or another site. Finally, there is a lender ALS between the provider and the lender. 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. 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. A Service Level Contract (SLA) is a contract describing the level of service a customer expects from their supplier. SLA को एक „और उपभोक्ता” बीच और उपभोक्ता, अनुबंध, एक महत्वपूर्ण घटक माना है. क्योंकि „और उपचारात्मक” (Remedial) है है काम भी कार्यों, जैसा sLA में है, जैसा. यह समझौता सरल भाषा में तैयार किया जाता है ताकि एक ग्राहक इसे स्पष्ट रूप से समझ सके.
इसमें ” को परिभाषित ” लिए शब्द शामिल हो हैं. सामान्यतः दूरसंचार कंपनियों ALS, इंटरनेट प्रदाताओं और IT service providers में उपयोग है। Since the late 1980s, SLAs have been used by fixed-line operators. Today, ALS is so widespread that large organizations have many different ALSs within the company itself. Two different units in an organization script an ALS, one unit being the customer and another the service provider. This helps maintain the same quality of service between different units of the organization and in several sites within the organization. This internal ALS script also compares the quality of service between an internal service and an external service provider.  Among the most important elements of a service level agreement is: Combine service and customer ALS and also apply to all users of an organization at the enterprise level.
