# 9. S3 Consideration for Multi-tenancy

VAST enables Cloud Service Providers (CSPs) to consolidate workloads and securely serve multiple tenants from a single platform while retaining strong isolation, flexible access controls, and simplified administration.

### S3-Specific Multi-Tenancy Identification

For S3, each tenant is mapped to its own **Access/Secret Keys**, along with its respective policy controls. This lets CSPs enforce fine-grained authorization per tenant while retaining operational simplicity.

- **S3 Bucket Names**: Must be globally unique across the platform, much like AWS S3.
- **Access Keys**: Provide per-user authentication and authorization.
- **Client IP Filters (Optional)**: An additional layer for securing multi-tenant S3 endpoints.
