A perfectly designed ALS is a set of communication rules for customers and service providers. Because SLAs are time sensitive, it can advance an efficient service with minimal time. SLAs can also help deflect the performance metrics of each provider in its service. A full ALS can reduce downtime and improve ROI for businesses. Application Case 4: The cloud service client must ensure that they can recover all data processed by their cloud service provider at the end of the service, regardless of why the service is interrupted. Service levels are essential to the effectiveness of ALS and must be realistic, achievable and measurable. You can refer to the quality, cost, punctuality, quantity or other appropriate measures that the customer requires of the provider. Select the measures that motivate good behavior. 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? In ICT, the introduction of suppliers is a recognized problem in which authorities that have contracts with suppliers of ict products or services for a given period cannot easily switch suppliers at the end of the contract, as essential information is not available to new suppliers. Application Case 3: The cloud service client must monitor (may) the delivery of services by its cloud service provider to ensure that it provides these services at agreed levels. AN ALS is a document agreed between a client and a service provider that defines the nature, quantity and quality of services to be provided. There is no requirement for a client to use an external service provider and an ALS can regulate services provided by internal sources. The parties may intend to establish a legally binding contractual relationship for ALS, which is less important for an ALS used for internal purposes. An ALS should address the following issues: Service elements include the specifics of the services provided (and what is excluded when there is room for doubt), service availability conditions, standards and slots for each level of service (e.g. prime time and non-prime time). B different levels of service), each party`s responsibilities, escalating procedures and cost/service compromises.
