Workflow SLAs 1 Workflow SLAs This snip is dedicated to the research regarding workflow SLAs. 1.1 Potential Research topics - (Automatic) construction of workflows by means of SLAs - Dynamic SLAs (for dynamic or undeterministic workflows?) - finding deterministic parts within the workflow - SLA is more then ensuring execution time: -- Quality of Service -- Security issues (e.g., run the workflow only on trusted resources) -- Reliability of resources -- Costs - What happens when SLAs are broken (fines etc.) - How to monitor SLAs? 1.1 Brainstorming - Analog to construction building: One company builds a house for you and you make a contract with the company to build the house with a certain quality within a certain timespan (this is the workflow). The company then subcontracts other companies to build the house and makes contracts with these subcontractors (this are subworkflows or atomic tasks/activities). If the company needs more time to build the house, then you get a discount etc... - SLA steering cycle: SLA Negotiation -> SLA Agreement -> SLA Monitoring -> SLA Violation -> SLA Enforcement -> ... __=========== under development! ============__ 2007-05-11 11:03:38.795 2007-05-10 17:22:04.591
