SaaS Approaches
• There are several strategies available for ISVs to build/migrate their products to a SaaS model. However, each approach has its own pros and cons.
• Two broad approaches,• Single Tenant / Hosted Model• Multi-Tenant Model
• While there are plenty of differences in the approach between these two models,• Single tenant approach is mostly for products that
are migrated from on-premise models to SaaS/cloud model
• Multi-tenant approach has become the defacto standard for all newly built SaaS solutions
