Overview

SAP BTP Connectivity provides secure access from SAP BTP applications to remote services across cloud, on-premise, and VPC environments.

Core Components

| Component | Purpose |

|-----------|---------|

| Destination Service | Manages connection metadata, authentication, routing |

| Connectivity Service | Enables Kubernetes workloads via Cloud Connector |

| Cloud Connector | Reverse proxy for secure on-premise tunneling |

| Connectivity Proxy | Kubernetes component for on-premise access |

| Transparent Proxy | Kubernetes component for unified destination access |

Supported Environments: Cloud Foundry, ABAP Environment, Kyma

Supported Protocols: HTTP/HTTPS, RFC, TCP (SOCKS5), LDAP/LDAPS, Mail

Quick Start

Create HTTP Destination (Cloud Foundry)

• Navigate: Connectivity > Destinations in BTP Cockpit
• Select: Create > From Scratch
• Configure:

   Name: my-destination
   Type: HTTP
   URL: https://api.example.com
   ProxyType: Internet
   Authentication: OAuth2ClientCredentials
   clientId: <your-client-id>
   clientSecret: <your-client-secret>
   tokenServiceURL: https://auth.example.com/oauth/token

Set Up Cloud Connector

• Download from SAP Tools
• Access: https://localhost:8443
• Login: Administrator / manage (change immediately)
• Add subaccount connection

Access Destination in Application (Node.js)

const { getDestination } = require('@sap-cloud-sdk/connectivity');
const destination = await getDestination({ destinationName: 'my-destination' });

Connectivity Scenarios

Cloud-to-Cloud

ProxyType: Internet
Authentication: OAuth2ClientCredentials | OAuth2SAMLBearerAssertion

Cloud-to-On-Premise

ProxyType: OnPremise
Authentication: BasicAuthentication | PrincipalPropagation

Requires Cloud Connector installation in on-premise network.

On-Premise-to-Cloud (Service Channels)

For on-premise systems accessing SAP BTP services via Cloud Connector.

Destination Types

| Type | Use Case | ProxyType | Common Authentication |

|------|----------|-----------|----------------------|

| HTTP | REST/OData APIs | Internet/OnPremise | OAuth2, Basic, Certificates |

| RFC | SAP systems | OnPremise | Basic, PrincipalPropagation |

| LDAP | Directory services | Internet | Basic, NoAuth |

| MAIL | Email protocols | Internet | Basic, NoAuth |

| TCP | Generic TCP | OnPremise | Basic |

Detailed configuration: See references/http-destinations.md, references/rfc-destinations.md, references/mail-tcp-ldap-destinations.md

Authentication Configuration

OAuth2ClientCredentials (Service-to-Service)

Authentication: OAuth2ClientCredentials
clientId: <client-id>
clientSecret: <client-secret>
tokenServiceURL: https://auth.example.com/oauth/token

OAuth2SAMLBearerAssertion (User Propagation)

Authentication: OAuth2SAMLBearerAssertion
audience: <target-audience>
clientKey: <client-key>
tokenServiceURL: https://auth.example.com/oauth2/token
KeyStoreLocation: <certificate-location>

PrincipalPropagation (On-Premise SSO)

Authentication: PrincipalPropagation
ProxyType: OnPremise

Requires Cloud Connector X.509 certificate generation.

Cloud Connector Setup

Installation

• Production: Windows MSI/Linux RPM packages (service registration)
• Development: Portable archive (manual execution)

Initial Configuration

• Access UI: https://<hostname>:8443
• Login: Administrator / manage
• Change password immediately
• Select mode: Master or Shadow
• Add subaccount connection

Access Control

Configure on-premise resource access:

• Backend Types: ABAP System, SAP Gateway, Non-SAP System, SAP HANA
• HTTP Access Control: System mapping + resource paths + policies

High Availability

• Master-Shadow: Primary + backup with synchronized config
• Requirements: Stable network, separate machines, identical versions

Kubernetes/Kyma Connectivity

Connectivity Proxy

Enables Kubernetes workloads to access on-premise systems.

Installation:

helm install connectivity-proxy \
  oci://registry-1.docker.io/sapse/connectivity-proxy \
  --version <version> --namespace <namespace> -f values.yaml

Transparent Proxy

Exposes BTP destinations as Kubernetes Services.

Installation:

helm install transparent-proxy \
  oci://registry-1.docker.io/sapse/transparent-proxy \
  --version <version> --namespace <namespace> -f values.yaml

Usage: Create Destination Custom Resource, access as Kubernetes Service.

Complete configuration: references/kubernetes-connectivity.md

Common Issues & Troubleshooting

HTTP Error Codes

| Code | Cause | Solution |

|------|-------|----------|

| 400 | Malformed request | Check request syntax |

| 401 | Authentication failure | Verify credentials/tokens |

| 405 | HTTPS instead of HTTP | Use http:// with port 20003 |

| 407 | Missing authorization | Add Proxy-Authorization: Bearer <token> |

| 503 | Cloud Connector offline | Check CC connection and Location ID |

Cloud Connector Issues

Cannot connect to subaccount:

• Verify region host URL
• Check firewall allows outbound HTTPS
• Verify subaccount credentials

Access denied to resource:

• Check access control configuration
• Verify virtual host mapping
• Check resource path policy

Security Best Practices

Cloud Connector

• Deploy in DMZ under IT control
• Change default password immediately
• Configure LDAP for user management
• Enable audit logging (All level for production)
• Deploy high availability (master + shadow)

Destinations

• Use OAuth over basic authentication
• Store credentials in Destination Service, not code
• Enable TLS for all connections
• Use mTLS for enhanced security

Critical Rules

Always Do

• Change Cloud Connector default password immediately
• Use HTTPS for all external connections
• Configure access control before exposing resources
• Enable audit logging in production
• Cache tokens and destinations appropriately

Never Do

• Expose Cloud Connector UI to internet
• Store credentials in application code
• Skip access control configuration
• Modify Cloud Connector Tomcat config files
• Run multiple master instances (split-brain)
