What this planner is
What it is. A rule-based planning worksheet for managed service providers. You answer a short set of questions and it writes a requirements profile: the isolation model to ask for, capacity headroom reasoning, backup and recovery design considerations, network, monitoring and management-plane concerns, and questions to put to a hosting provider. Every result shows what drove it.
What it is not. It does not measure, scan, audit or test any real system, and it is not a certification. It names no supplier or product, quotes no price and states no capacity figure. All processing happens in your browser: your answers are not sent anywhere and are not stored.
Answer the form and choose Build requirements profile. The result appears here.
How the rules work
The planner combines your answers into three levels. Isolation takes the higher of a security level (from compliance pressure and data residency) and a performance level (from the workload mix, where databases and hosted desktops weigh most), and moves up a step when both are demanding. Recovery class follows whichever of your recovery point and recovery time is stricter. Headroom posture rises with growth, tight recovery times, around-the-clock support, latency-sensitive workloads and hosted desktops. A harder answer never produces an easier result.
The tenant count does not change the isolation level. It changes the advice: at larger counts the output tells you to automate network builds, plan for many tenants recovering at once, and consider N+2 failure tolerance when recovery times are tight.
