Variability middleware for multi-tenant SaaS applications
Dimitri Van Landuyt, Stefan Walraven, Wouter Joosen · 2015
Software product line engineering (SPLE) and variability enforcement techniques have been applied to run-time adaptive systems for quite some years, also in the context of multi-tenant Software-as-a-Service (SaaS) applications. The focus has been mainly on (1) the pre-deployment phases of the development life cycle and (2) fine-grained (tenant-level), run-time activation of specific variants. However, with upcoming trends such as DevOps and continuous delivery and deployment, operational aspects become increasingly important.
