Agreeing on and Controlling Business Service Levels in Service-Oriented Architectures |
This paper introduces Business Service Levels (BSLs) as a generalised concept to agree on feasibility and workload of business processes hosted in service-oriented architectures. BSLs loosen the coupling between technical service provision and business service consumption by offering an alternative to technical service level agreements. To controll the BSL compliance at runtime an technical approach is introduced and implemented as proof-of-concept. It retrieves state or load information from a technical monitoring system and technical topology information from a CMDB. Based on those, this component estimates a business process’s feasibility and workload. To maintain the contracted BSLs it actively controlls the request flow towards the services.
