These changes must be taken into account through the scoping and strategy phases on current and recurring tasks, both ad hoc and periodic. To address these risks, the policies and procedures of CSP and Cloud customers need to be synchronized as closely as possible, as cloud risk management must be a common activity to be successfully implemented. If the service provider is taken over by another entity or merges with another entity, the client can expect his ALS to remain in effect, but that may not be the case. The agreement may need to be renegotiated. Don`t make assumptions; Note, however, that the new owner does not want to alienate existing customers, so they can choose to honor existing SLAs. Make sure the metrics reflect factors that are in the service provider`s control. To motivate good behavior, ALS metrics must reflect factors in the control of the outsourcer. A typical mistake is to penalize the service provider for delays caused by the customer`s lack of performance. If the client.
B provides application code change specifications several weeks late, making it unfair and demotivating to keep the service provider on a pre-indicated delivery date. AlS bias by measuring client performance in interdependent actions is a good way to focus on expected results. The ALS should contain not only a description of the services to be provided and their expected levels of service, but also metrics to measure the services, obligations and responsibilities of each party, corrective measures or penalties in the event of a breach, and a protocol for adding and removing measures. Metric for the recovery of the average system: this highlights the time expected for a complete recovery in a system resistant in case or after a service failure. This is usually measured in minutes, hours and days. When sending a PSR, the customer must include the expected levels of service as part of the requirement. This has an impact on suppliers` offers and prices and may even influence the supplier`s decision to respond. If you need z.B. 99.999 percent availability for a system and the provider cannot meet this requirement with the indicated design, it can offer another, more robust solution. The goal should be to fairly integrate good practices and requirements that maintain service efficiency and avoid additional costs.
Service level agreements define the obligations of service providers to their customers. One of these obligations is the compensation that customers receive in the event of deterioration or interruption of service. This obligation exposes the service provider to the risk of paying large sums of money in the event of massive disruptions. The assessment of this risk is provisional for any counter-measures that the service provider wishes to take to reduce the risk. In this contribution, we assess the distribution of economic losses related to service outages as part of a Markovian ON-OFF service model.
