Speaker: Professor Jun Han (Swinburne University of Technology, Melbourne, Australia)

Abstract:

With the emergence of Cloud Computing and maturity of Service Oriented Architecture (SOA), the Software-as-a-Service (SaaS) delivery model has gained popularity, due to its advantages in such aspects as lower start-up, reduced operating costs and quicker time to market. An SaaS vendor owns and takes the responsibility of maintaining a single application for multiple clients/tenants who may have similar but also varying requirements. Business process modelling (BPM) approaches can be used to package service offerings to meet these varying requirements on a shared basis. However, the customization of these business processes to achieve runtime sharing and variability can be challenging. In this talk we discuss the challenges arising from single-instance multi-tenancy, and present our approach to modelling and deploying adaptive business processes for multi-tenant cloud/SaaS applications to address those challenges.
