Platform Fundamentals

Account Hierarchy

Global Account (SAP contract)
├── Directory (optional, up to 7 levels)
│   └── Subaccount (region-specific, apps run here)
│       ├── Cloud Foundry Org → Spaces
│       └── Kyma Cluster → Namespaces
└── Subaccount

Key Points:

• Global account = contract with SAP (one per commercial model)
• Directory = groups subaccounts (max 7 levels deep)
• Subaccount = deployed in specific region, enables runtimes
• Use labels for virtual grouping (Dev/Test/Prod, cost centers)

Environments

Commercial Models

• Consumption-Based (BTPEA/CPEA): Flexible access, best for pilots
• Subscription-Based: Fixed-cost for known service needs

Best Practice: Start with consumption-based, move to subscription for stable workloads.

Account Model Setup

Simple Model (3 subaccounts)

Global Account
├── Dev Subaccount
├── Test Subaccount
└── Prod Subaccount

Best for: Initial implementations, single team, <3 projects

Directory Model (scalable)

Global Account
├── Directory: HR
│   ├── hr-dev / hr-test / hr-prod
├── Directory: Sales
│   ├── sales-dev / sales-test / sales-prod
└── Directory: Central IT
    ├── api-management
    └── shared-services

Best for: Multiple teams, cost allocation, complex governance

Naming Conventions

Tip: Derive CF org/Kyma names from subaccount names for consistency.

Security and Authentication

Identity Provider Setup

Always use SAP Cloud Identity Services - Identity Authentication

Corporate IdP → Identity Authentication (proxy) → SAP BTP

Critical Steps:

1. Add multiple administrators (different time zones)
2. Enable MFA for all admins
3. Configure security alerts
4. Set up backup admins in SAP ID Service

Authorization Methods

Destination Authentication

Recommended:

• PrincipalPropagation - SAP on-premise systems
• OAuth2SAMLBearerAssertion - Third-party systems
• OAuth2JWTBearer - User token exchange

Avoid in Production:

• BasicAuthentication
• OAuth2Password

See: references/security-and-authentication.md for complete guidance

Connectivity

Remote System Access

• Internet Services: Destinations with authentication
• On-Premise Systems: Destinations + Cloud Connector

Cloud Connector

• Lightweight on-premise agent
• Secure tunnel to SAP BTP (no inbound ports)
• Fine-grained access control
• Supports RFC and HTTP protocols
• Enables principal propagation

Note: Each subaccount needs separate Cloud Connector config.

Governance and Teams

Required Teams

Platform Engineering Team (Center of Excellence):

• Manages cloud landscape infrastructure
• Handles account operations, build infrastructure
• Creates governance and compliance guidelines
• Does NOT manage individual application lifecycles

Cloud Development Teams:

• Follow DevOps (develop AND operate)
• Responsible for application lifecycle
• Regular maintenance (e.g., UI updates every 6 months)

Essential Documentation

1. Onboarding Doc: Organization, app IDs, timeline, tech stack
2. Security Doc: Data sensitivity, policies, auth framework
3. Services Catalog: Templates for destinations, builds, schemas

Development

Programming Models

SAP CAP (Cloud Application Programming Model):

• Framework with languages, libraries, tools
• Supports Java, JavaScript, TypeScript
• Enterprise-grade services and data models

ABAP Cloud:

• Modern ABAP for cloud-ready apps
• RAP (RESTful ABAP Programming Model)
• Extensions for ABAP-based products

Development Lifecycle

1. Explore: Business opportunity, team roles
2. Discover: Use cases, technology options
3. Design: UX design, domain-driven design
4. Deliver: Landscape setup, development
5. Run and Scale: Feedback, optimization

AI Development

SAP BTP provides AI capabilities through SAP AI Core for:

• Generative AI (LLMs, RAG)
• Narrow AI (classical ML)

Key Resources:

• Repository: SAP-samples/sap-btp-ai-best-practices
• Documentation: https://btp-ai-bp.docs.sap/

Best Practices:

• Use service keys for secure authentication
• Implement PII data masking
• Build RAG with SAP HANA Cloud Vector Engine
• Configure content filtering
• Monitor model drift

Use Cases: 20+ samples including chatbots, PDF extraction, procurement.

See: references/ai-development-best-practices.md for patterns and examples

Deployment and Delivery

Deployment Methods

Cloud Foundry/Neo:

• Package as MTA archive
• Deploy via: BTP Cockpit, CF CLI, Business Application Studio

Kyma:

• Docker images (Dockerfile or Cloud Native Buildpacks)
• Helm charts for production
• Deploy via SAP Continuous Integration and Delivery

CI/CD Approaches

SAP Continuous Integration and Delivery:

• Low expertise required
• Ready-to-use infrastructure
• Direct SAP support

Project "Piper":

• High expertise required
• Jenkins-based
• Open-source community support

Best Practice: Combine CI/CD with SAP Cloud Transport Management for governance + agility.

See: references/deployment-and-delivery.md for detailed configs

High Availability and Failover

Multi-Region Architecture

Custom Domain URL
       │
    Load Balancer
       ├── Region 1 (active)
       └── Region 2 (passive/active)

Failover Implementation

Four Core Principles:

1. Deploy in Two Regions: Near users and backend systems
2. Keep Synced: CI/CD pipeline or Cloud Transport Management
3. Define Detection: Monitor 5xx errors, timeouts
4. Plan Failback: Visual differentiation, user-driven

Legal: Check cross-region data processing restrictions.

See: references/failover-and-resilience.md for implementation details

Operations and Monitoring

Go-Live Checklist

1. Deploy to production
2. Set go-live timeframe (avoid quarter-end)
3. Embed in SAP Fiori Launchpad
4. Provision business users
5. Configure role collections

Monitoring Tools

SAP Cloud ALM (Enterprise Support):

• Real User Monitoring
• Health Monitoring
• Integration and Exception Monitoring
• Job Automation Monitoring

SAP Cloud Logging:

• Observability across CF, Kyma, Kubernetes

SAP Alert Notification:

• Multi-channel notifications (email, chat, ticketing)

Cost Management

Best Practices

1. Check *Costs and Usage* monthly
2. Provide minimal required entitlements
3. Use labels for cost allocation
4. Set up automated alerts (Usage Data Management + Alert Notification)

Contract Strategies

• Consolidate subscriptions in one global account
• Use hybrid accounts for mixed workloads
• Note: Consumption credits non-transferable between global accounts
