The prescribed technical standards and specifications of the metric service technical interface must 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. SLAs often include many elements, from the definition of services to the termination of the contract.  In order to ensure rigorous compliance with ALS, these agreements are often designed with specific lines of demarcation and the parties concerned must meet regularly to create an open communication forum. Rewards and penalties that apply to the supplier are often set. Most ALS also leave room for regular (annual) revisions to make changes.  As 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.  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? 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. However, in the case of critical services, customers should invest in third-party tools to automatically collect sLA performance data that provide objective performance measurement. IT service organizations that manage multiple service providers may wish to enter into Operational Level Agreements (OLA) that explain how some parties involved in the IT service delivery process interact with each other to maintain performance. Overview – Service Level Agreement – Contents – Types of support required and support level – Service Level Requirements/Targets The main point is the construction of a new level for the grid, cloud or SOA middleware, which can create a trading mechanism between service providers and consumers. For example, the EU-funded Framework SLA@SOI 7 research projectexplores aspects of multi-level, multi-supplier slas within service-based infrastructure and cloud computing, while another EU-funded project, VISION Cloud, has delivered results in terms of content-based ALS.
