Same situation applies to the cloudbased software applications. In SaaS (Software as a Service) Model Most of the web applications are SaaS – But not Multi-Tenant…! Multi-Tenant Examples, Highrise Jira YaY In these systems, organizations make their accounts and they are provided a look and feel of their own „Home‟
Why this is so important? Data is vital for some businesses. Should be able to isolate data among tenants in SaaS model. If we provide it…. We have Competitive Advantage.
That implies…Data Architecture is the mostsignificant factor in a MultiTenant Application.
We can identify 3 differentarchitectures at present… Separate DB – Separate Schema Shared DB – Separate Schema Shared DB – Shared Schema
Separate DB – Separate Schema Extendibilitywith tenant specific requirements Easy Backup High Cost Suitable for Medical and Banking applications in spite of high cost
Shared DB – Separate Schema Separate set of tables for each tenant in same DB Extendible and easy to implement Suitable if No. of Tenants < 100 Low cost than the previous one
Shared DB – Shared Schema Lowest Cost Additional development effort Less security Each row contains tenant Id Suitable for a huge cluster of tiny tenants
Regularity Consideration (legal requirements of companies) Skills set of development team etc…
InYayCRM we have invented a model that is supported all those architectures You can, - distribute databases in a server farm - expand and shrink the number of databases - move tenants among databases
