Understanding Multi-Tenancy in B2B SaaS
Multi-tenancy refers to a software architecture where a single instance of an application serves multiple distinct groups of users, known as tenants. In a B2B context, each tenant is typically a separate company.
- Core Concept: A single application instance and backend infrastructure are shared, but each company's data, settings, and user base are isolated from others.
- Example: Slack is a prime example, where a single user can belong to multiple workspaces (organizations), each with its own team, channels, and data, entirely separate from other workspaces.
- Challenge: The primary challenge lies in identifying which organization a user belongs to upon login and assigning them the correct permissions. This necessitates sophisticated systems for managing organization switching, membership, and access control.
