That way you can have all the data of all the companies in the same table / database and at application level you can control what company is tied to which companyId and determine which data to display for certain company. Risk of "noisy neighbors"tenants can impact the performance of the system for all others due to a lack of isolation and all competing for the same resources, One-size-fits-all performance tuning and stability, Approach #2: Single Database, Separate Schema, Separate tables for each tenant, each set under a tenant-specific schema, Schema updates more involved, needing to be rolled out to n tenants, Limited to scaling-up hardware, rather than scaling out, Some added complexity to maintain a registry of, Approach #4 : Multiple Databases, Multiple Tenants Per Database, Shared Schema, Tenants share a database and schema with other tenants, but are spread over multiple databases, Choose to balance between overhead of more databases to maintain (lower tenant density) versus fewer (higher tenant density). This can be achieved by: Virtual machine technology it provides an emulator on a hardware to run multiple operating systems on it while sharing the same physical hardware. Are You Ready for SAP S/4HANA Running on Cloud? The applications repository layer is aware of the tenant-specific database, and it is using the information from the current context to help the applications domain layers. using a prefix someprefix_), Adding a text column called id_tenant to every table to store the name of the tenant the row belongs to, Creating a trigger for each table to automatically store the current database username to the id_tenant column before inserting a new row, Creating a view for each table with the original table name with all the columns except id_tenant.

Also, we add security to tenants using JWT. Therefore, the tenant identifier is the database catalog itself. The ITenantService is passed to the constructor via dependency injection and used to resolve and store the tenant identifier. There are three multi-tenancy models and each has its own level of complexity and cost. Are you going to have 10s, 100s, 1000s of clients?
