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. Measures should be designed so that bad conduct is not rewarded by both parties. If z.B. a service level is violated because the customer does not provide information on time, the provider should not be penalized. This service level agreement for Microsoft Online Services (this “SLA”) is part of your Microsoft volume license agreement (the “agreement”). The basic terms that are used in this ALS but are not defined have the meaning assigned to you in the agreement. This ALS applies to microsoft online services (a “service” or “services” listed below), but does not apply to separate services that are related to or related to services, or to local software that is part of a service. A web service level agreement (WSLA) is a standard for monitoring compliance with web services according to the service level agreement. It allows authors to indicate performance metrics assigned to a web application, desired performance goals, and actions to perform if performance is not achieved.
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).  Select the measures that motivate good behaviour. The first objective of any metric is to motivate the corresponding behaviors on behalf of the client and service provider. Each side of the relationship tries to optimize its actions to achieve the performance goals defined by the metrics. First, focus on the behavior you want to motivate. Then test your metrics by placing yourself instead of the other side. How would you optimize your performance? Does this optimization support the results initially desired? Because applications are moved from dedicated hardware to the cloud, they must reach the same level of service, or even more sophisticated than conventional installations. SLAs for cloud services focus on data center features and more recently include network features (see Carrier`s Cloud) to support end-to-end SLAs.
 Your cloud provider needs hardware software and (potentially) to operate its services. The provider should describe the hardware that cloud services rely on, including servers and other equipment. If you know the specifications of your cloud`s devices and software, you`ll be able to better understand the specifics of building your cloud environment. and what you need to educate your employees. SLAs are an integral part of an IT provider contract. An ALS brings together information about all contract services and their expected reliability in one document.
