Tips for Moving to a Multi-Tenant Setup

Adrian Hills continues a series on multi-tenant SQL Server:

What you knew a few years ago might differ significantly from the reality today, whether you started off with a single tenant system that you pivoted quickly to support multiple tenants, or you envisioned 10s of tenants and ended up with 1000s. Whatever that reality is, when you experience pain points around the 3 considerations I covered in part 1 of this series (security, maintainability, and scalability), it can lead to a need to change the multi-tenancy approach you’re using. Often, the biggest driver for change is around performance and scalability and typically tends to be related to a need to move from a less-isolated multi-tenancy approach (single database) to a more-isolated approach that supports the scaling out of workloads (multiple databases).

In the steps below, I’ll cover the general path you can follow to successfully make an architectural change like this to the database layer. As a provider of database performance monitoring and DataOps tools, SentryOne offers some tools that can come in handy along the way, so I’ll call those out as we go.
