Abstract:
Service Level Agreements (SLA) are contracts established between Software as a Service (SaaS) providers and Platform as a Service (PaaS) providers related to various properties of the services running on the platform. We propose a generic method to evaluate to what extent SaaS provider proposed Quality of Service (QoS) targets, such as response time or maximal throughput, can be guaranteed with constraints on workload, resources and cost. These ``what-if'' evaluations are based on small scale benchmarking and ability of the application to be scaled. The approach allows us to estimate with minimal costs, to what extend a given SLA can be accepted by both client and provider of a given PaaS.
