# DuploCloud Tenancy Models

DuploCloud supports a variety of deployment models, from basic multi-Tenant applications to complex single-Tenant deployments within customer environments. These models cater to different security needs, allowing customers to achieve their desired isolation level while maintaining operational efficiency. 

DuploCloud-supported tenancy models, outlined below, include:

* [Application-Managed Multi-Tenancy](#application-managed-multi-tenancy)
* [DuploCloud Tenant-per-Customer](#duplocloud-tenant-per-customer)
* [DuploCloud Infrastructure-per-Customer](#duplocloud-infrastructure-per-customer)
* [Cloud Account-per-Customer](#cloud-account-per-customer)
* [Hybrid Model](#hybrid-model)
* [On-Premises ](#special-hybrid-case-single-tenant-deployment-in-external-kubernetes-cluster)

## Tenancy Deployment Models

### Application-Managed Multi-Tenancy

* **Description**: The application manages Tenant isolation with DuploCloud structured pooled tenancy.&#x20;
* **Use Case**: The most common scenario is where the application logic isolates customer data. DuploCloud Tenants are then used to isolate development environments (i.e., Nonprod and Prod).&#x20;
* **Infrastructure**:
  * Shared DuploCloud Infrastructure (VPC, Tenant, VM/instances, S3 bucket, RDS). Cluster/namespace can also be shared.&#x20;
  * Scaling: Increase compute instances for Kubernetes worker nodes as needed.

### DuploCloud Tenant-per-Customer

* **Description**: Each customer gets a separate DuploCloud Tenant.
* **Use Case**: Suitable for older applications not designed for multi-tenancy, or security and compliance needs.
* **Infrastructure**:
  * Shared network layer (VPC).
  * Separate Tenants per customer with security boundaries (Security Group, KMS Key, SSH Key, Kubernetes Namespace).
  * Kubernetes Cluster is shared and boundaries are through the Namespace.

### DuploCloud Infrastructure-per-Customer

* **Description**: Each customer gets a separate DuploCloud Infrastructure.
* **Use Case**: Provides a higher security boundary at the network layer where customer access and data are separated.
* **Infrastructure**:
  * Separate VPC and Network Resources for each customer.
  * Clusters are inherently separate through Tenants isolated in different Infrastructures.
  * Higher cost due to duplicated resources and Operational Overhead.

### Cloud Account-per-Customer

* **Description**: Each customer gets a separate cloud account.
* **Use Case**: The least common model, used for customers requiring complete isolation.
* **Infrastructure**:
  * Separate accounts with a DuploCloud Platform installed in each.
  * Each account then has its own DuploCloud Infrastructure and Tenant.

### Hybrid Model

* **Description**: Combination of the above models as needed to meet specific requirements.
* **Use Case**: Diverse customer needs.
* **Infrastructure**:
  * A combination of previous models.
  * Organization-specific depending on requirements: some organizations may be in a pooled application environment whereas others may be more isolated through Tenant boundaries.

### Special Hybrid Case: Single-Tenant Deployment in an External Kubernetes Cluster

* **Description**: DuploCloud imports existing Kubernetes clusters from external environments.
* **Use Case**: A cluster and resources already exist, or customers require the application or services solution running inside their client's cloud account. Customers are comfortable creating their own Kubernetes environments.
* **Infrastructure**:
  * Customer's Cloud Account or On-Premises Cluster (EKS, AKS, GKE, Oracle, DOKS, etc.) in conjunction with a DuploCloud Infrastructure. This could be any Kubernetes Cluster not created by DuploCloud.&#x20;
  * Manages both multi-Tenant and single-Tenant environments from the DuploCloud UI.
