# FAQ

> Frequently asked questions about Grand Central iPaaS

<AccordionGroup>
  <Accordion title="Does Grand Central offer DDoS protection?">
    Yes. Grand Central offers **DDoS Protection** as a platform add-on. The service uses Azure DDoS Protection to provide advanced mitigation against volumetric, protocol, and application-layer attacks with sub-second response times.

    For full details and how to enable it, see [Add-ons](/platform/add-ons).

  <Accordion title="Does my code run in a shared environment?">
    No. Each customer gets a **dedicated installation**, not a shared multi-tenant cluster. The isolation model includes:

    * **Separate GitHub repositories per customer**: Each customer has their own `applications-live` and `self-service` repositories
    * **Separate AKS clusters per installation**: Each installation has its own cluster, or at a minimum its own namespaces and runtimes
    * **Separate SOPS keys** per customer environment, linked to that customer's Azure Key Vault
    * **Separate APIM configuration** per installation
    * **Separate Microsoft Entra ID roles** scoped to each installation's environments

    Grand Central is **single-tenant by design**. Each customer has isolated infrastructure, isolated repositories, and isolated secrets. Different customers' connectors never run side-by-side in a shared runtime.
