## 2. Account Model

### Hierarchy
```
Global Account → Directory (optional) → Subaccount (region-specific)
                                    ↓ CF: Org → Spaces
                                    ↓ Kyma: Cluster → Namespaces
                                    ↓ ABAP: System instance
```

### Key Entities
- **Global Account**: Contract with SAP, region-independent, manages entitlements
- **Directory**: Organizational container, up to 7 levels, optional entitlement management
- **Subaccount**: Region-specific deployment target hosting apps and services
- **Labels**: Metadata tags (up to 10 values per label)

### Account Types
- **Trial**: 90-day free exploration (4GB memory, 10 routes, 40 services, daily stops)
- **Enterprise**: Production use based on commercial contract
- **Free Tier**: Long-term testing with service-specific limits, no SLA

## 3. Environments

SAP BTP offers four runtime environments at the subaccount level:

### Cloud Foundry Environment
Open PaaS with polyglot support. Features: multiple buildpacks (Java, Node.js, Python, Go, PHP), spaces for separation, auto-scaling, SAP HANA integration.
```bash
cf login -a [https://api.cf.<region>.hana.ondemand.com](https://api.cf.<region>.hana.ondemand.com)
cf push my-app
cf bind-service my-app my-service-instance
```
**Structure**: Subaccount → Org (1:1) → Spaces

### Kyma Environment
Managed Kubernetes runtime based on open-source Kyma.
- **Default Modules**: istio (service mesh), api-gateway, btp-operator
- **Optional Modules**: serverless, eventing, application-connector, telemetry, keda
**Structure**: Subaccount → Cluster (1:1) → Namespaces

### ABAP Environment
Cloud ABAP development with RAP, CDS, SAP Fiori integration, ADT, 1:1 SAP HANA database per system.
**Use Cases**: Extend S/4HANA Cloud, build new cloud applications, transform ABAP custom code

### Neo Environment
**Status**: Sunsetting December 31, 2028. **Recommendation**: Migrate to CF/Kyma.

## 4. Commercial Models

### Consumption-Based
Access all eligible services with flexible usage. Flavors: SAP BTPEA, CPEA, Pay-As-You-Go. Benefits: Switch services on/off, access current and future services.

### Subscription-Based
Fixed cost for selected services, pay irrespective of consumption. Additional services require contract modification.

**Best Practice**: Use consumption-based for pilots, subscription for stable workloads.

## 5. Entitlements and Quotas

### Definitions
- **Entitlement**: Right to provision and consume a service plan
- **Quota**: Numeric quantity of consumption allowed
- **Service Plan**: Variant of a service (e.g., t-shirt sizes)

### Quota Types
- **Fixed**: Upper limit (subscription model)
- **Unlimited**: No limit, billed by usage (consumption model)

### Distribution Flow
Global Account → Directory (reserves) → Subaccount (consumes) → CF Space (optional)

## 6. Regions and Infrastructure

### Region Providers

| Provider | Examples |
|----------|----------|
| **SAP** | eu10, us10, ap10 |
| **AWS** | eu10, us10, ap10, ap11, ap12 |
| **Azure** | eu20, us20, ap20, jp20 |
| **Google Cloud** | us30, in30 |
| **Alibaba Cloud** | cn40 |

### Key Considerations

- Each subaccount assigned to exactly one region
- Multi-region requires separate deployments
- EU Access available in specific regions for compliance
- API endpoints vary by region instance

### Availability Zones

Multi-AZ deployment for high availability:
- Isolated power, network, cooling
- Automatic failover within region
- Both CF and Kyma support multi-AZ
