This model provides a dedicated data plane for each customer while retaining the shared control plane hosted by Decube.

#### Components:

* **Control Plane** (same as SaaS)
* **Single-Tenant Data Plane** (dedicated to one customer)
  * Metadata API
  * Metadata Storage
  * Distributed Job Scheduler
  * Metadata Collector
  * Data Quality Monitoring

#### How it Works:

* A dedicated infrastructure ensures isolation and compliance adherence.
* Metadata is securely collected using the same read-only methods as in Multi-Tenant SaaS.
* Ideal for customers with stricter data handling policies or compliance requirements.

#### Data Security:

* Logical and infrastructure-level isolation is maintained.
* Data remains within the customer’s environment unless explicitly configured otherwise.
