If the number of users within a workflow management system (WFMS) increases,
a central workflow server (WF-server) and a
single local area network (LAN) may become overloaded. The approach
presented in this paper describes an execution
environment which is able to manage a growing number of users by adding
new servers and subnets. The basic idea is to
decompose processes into parts which are controlled by different WF-servers.
That is, during the execution of a workflow instance
its execution (step) control may migrate from one WF-server to another.
By selecting the appropriate physical servers (for hosting
the WF-servers) in the appropriate LANs, communication costs and individual
WF-server workload can be reduced significantly.
