SaaS Maturity Model

Level 4 Optimizing Highly secure multi-tenancy model (infrastructure, application & database) implemented withability to configure “any” licensing model, support hard SLAs, configure per-client businessprocess flows, and predictive monitoring (continuously improving model)

Level 3 Adaptive Multi-tenancy is supported via single version and “instance” of the application with support for on-demand scalability with advanced support for diverse licensing models, integration & monitoring

Level 2 Managed Applications run on consolidated infrastructure to serve multiple clients with basic support for traditional licensing models, global usage, integration, security & monitoring

Level 1 Reactive Each new customer requires a separate instance of the application maintained on a per tenantbasis
