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

2. Motivation

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

4. 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

5. 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

6. Configurable Process Models

13. YAWL

14. 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

15. 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

20. 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
