When orchestrating highly distributed and data-intensive web service work flows the geographical placement of the orchestration engine can greatly affect the overall performance of a work flow. The authors present CloudForecast: a web service framework and analysis tool which, given a work flow specification, computes the optimal Amazon EC2 cloud region to automatically deploy the orchestration engine and execute the work flow. They use geographical distance of the work flow, network latency and HTTP round-trip time between Amazon cloud regions and the work flow nodes to find a ranking of cloud regions.
