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.  The fundamental advantage of cloud computing is the sharing of 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. The techniques described help you assess service costs against quality, resulting in competitive advantages and business results. They can be applied to any sector, delivery or support service.

The aim is to make the control possibilities for the client transparent and to accurately describe overly safe performance characteristics such as performance level, reaction time and speed of machining. An important element is the level of service, which describes the agreed quality of service and contains information about the range of services (e.g. time. B, volume), availability, supplier response time, etc. The typical example is the operation of servers, which are 24 hours a day, 7 days a week with a maximum z.B failure rate of 0.1% per year and a response time of 30 minutes after reporting the damage by an external service provider that must be.  “A level of service agreement is the instrument that ensures the provision of a consistent, appropriate and timely quality of service to meet business needs at the right price.
