The basis for SAAS is a Multi-tenancy architecture that allows multiple tenants (organizations) access to multiple instances of the software hosted on a single server. The client application is not aware of multi-tenant implementation. On the other hand, a single tenant's workload could impact how the service performs for others. Application pools they are server-side sandboxes for isolating application processes. How to Implement Multi-Tenancy with SQL Server (Part 3), What is Multi-Tenancy? Create storage efficient pluggable databases in seconds that mirror full data set copies of the source pluggable database for development and testing environments. User session virtualization dynamically allocates computing resources to user session within a multi-user operating system.

Scaling and Virtualization for Multi-tenant Application. A tenant identifier (tenant key) associates every row with the right tenant. For that reason, creating a new DbContext per operation should usually be fine. Db2 and Db2 on Cloud also provide row-level access control, and even column-level access control, to further refine access in both a shared or multi-tenant environment.
