Service availability: The time available to use the service. This can be measured using the time window, z.B 99.5% availability between hours 8 a.m. and 6 p.m. and more or less availability at other times. E-commerce processes are generally extremely aggressive. 99.999 percent operating time is an unusual requirement for a website that generates millions of dollars per hour. The main point is to create a new level for the grid, cloud or SOA middleware, capable of creating 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. Management elements should include definitions of standards and methods of measurement, reporting processes, content and frequency, a dispute resolution procedure, a compensation clause to protect the client from third-party disputes arising from breaches of service (which should already be included in the contract) and a mechanism to update the agreement if necessary.
For example, making a reading-only catalog available is quite simple for customers. Although the catalog can have a very high value, it is quite easy to restore backups with minimal impact on the customer. However, if the same service has online purchases with financial transactions and customer data, the level of risk and importance to the business have just increased. The type of service is an integral part of determining the right ALS. The elasticity and configurability of infrastructure is part of the reason people move applications around the cloud. Your services must be manageable at all times to provide this benefit. Oracle provides management SLAs to ensure you can manage, monitor and modify resources. OpenAIRE can offer applications as a service (z.B.
