Maintaining service level agreements is part of service level management. Each time a service is changed or the service level objective of a service change, the service level agreement must be reviewed and revised. The new level of service agreement must reflect changes to the service or service level objectives. Therefore, the management of service level agreements is an important part of the continuous improvement of the ItIL service. Because it is an internal document, legal language is only used to maintain the form of the document (i.e., it looks like an agreement), but the content focuses on the definition of the service that is provided, for example. B the furniture service supports the air conditioning of the data centers. The important thing is that the OLA must support ALS. This means that z.B. if you use a database administrator from another organizational unit and you have an ALS that indicates that database-related incidents need to be corrected within 4 hours (for priority 2 incidents), the OLA must have at least the same parameters for these incidents or, as I suggest , better still (p.B 3 hours). 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).  Service level agreements are also defined at different levels: to achieve this understanding, it is necessary to decouple the service and see what you measure. This is really a “light bulb moment” when you take a design approach to provide a service and measure its delivery.
For example, in the Airline business, you realize that the true value of an ALS allows customers to complete their journey. Who cares if the computer system has “increased” by 99.8%? The second type of service level agreement structure is customer-based ALS. A customer-based ALS is an agreement with a customer that covers all of that customer`s services in Iron Mouth. Let`s look at the relationship between you and your telecommunications operator. They use voice services, SMS services, data services and several other services of the telecommunications operator. For all these services, you only have a contract between you and the telecommunications operator.
