YAWL in the Cloud: Supporting Process Sharing and Variability Dennis Schunselaar, Verbeek, Reijers, Van der Aalst

Motivation

Traditional situation IS = Information System E = Event log M = Models

To-be situation IS-SaaS = Information System (SaaS-based BPMS) Multi-tenancy IS-SaaS = Information System (SaaS-based BPMS) E = Event log CM = Configurable Models C = Configuration

Overview Design time 2 3 Post run-time Deploy time 1 4 2 2 Run time Multi-tenancy IS-SaaS = Information System (SaaS-based BPMS) E = Event log CM = Configurable Models C = Configuration

Configurable Process Models

YAWL

Architecture Management Component YAWL in the cloud Router In 1 Router In k Load balancer DB Router Out 1 Router Out l Load balancer - No changes to YAWL - No difference for the end-user

Implementation A A A A R R R R A R : Get All Running Cases Per Tenant Router In 1 R R R DB Router Out 1 A - Multi-tenancy R : Get All Running Cases Per Tenant R

Implementation - No changes to YAWL - No difference for the end-user Management Component Router In 1 Router In k Load balancer DB Router Out 1 Router Out l Load balancer - No changes to YAWL - No difference for the end-user - Management component R : Get All Running Cases Per Tenant A

Conclusion Many advantages of moving non-competitive organisations to the cloud Proof-of-concept implementation showing the feasibility of multiple organisations sharing a single BPM Time for commercial uptake to show the sketched benefits
