Overview of SAP Leonardo and Google Cloud Platform Integration
- SAP Leonardo is a comprehensive digital innovation system integrating advanced technology like IoT, Machine Learning, and Blockchain to drive business growth and innovation.
- Google Cloud Platform (GCP) offers cloud computing services that provide a wide array of capabilities and tools for data storage, machine learning, and seamless integration with third-party services.
Set Up Your Environment
- Before commencing with the integration, ensure you have an active account on both SAP Cloud Platform and Google Cloud Platform. Create projects in both if not already existing.
- Ensure you have appropriate permissions to access and manipulate both environments. This often involves administrator permissions, especially when setting up APIs and cloud functions.
Enable Required APIs and Services
- In the Google Cloud Platform Console, navigate to the APIs & Services section and enable APIs such as Cloud IoT Core, Pub/Sub, and any other APIs that you will use for integration.
- Within SAP Cloud Platform, ensure that relevant environment services are activated, particularly those related to API Management and Integration Suite.
Configure SAP Leonardo IoT
- Log into your SAP Cloud Platform cockpit and access the IoT service. Define the device model and capabilities you want to utilize in your integration with GCP.
- Create a device and register it in the SAP Leonardo IoT service.
- Generate security tokens that will be used for secure communication between SAP IoT devices and other cloud platforms.
Set Up Google Cloud IoT Core
- Navigate to the Google Cloud IoT Core section in the GCP Console. Create a registries and within these registries, register devices that will be corresponding to the devices in SAP Leonardo.
- Ensure you configure authentication using the public keys from SAP Leonardo IoT security tokens for verification in the Cloud IoT Core.
Establish Integration Workflow
- Define and set up Pub/Sub topics in the GCP to receive data from IoT Core that can then be redirected to other Google Cloud services or external applications as needed.
- Use SAP Cloud Platform Integration (or similar middleware) to connect SAP Leonardo IoT outputs directly to GCP endpoints.
Create Cloud Functions for Data Processing
- Consider creating serverless functions in GCP Cloud Functions to process data coming in from SAP Leonardo, such as converting formats, or feeding data into BigQuery for further analysis.
exports.processData = (event, context) => {
const message = Buffer.from(event.data, 'base64').toString();
console.log(`Received message: ${message}`);
// Process the message data
};
Test the Integration
- Simulate IoT data sending from SAP Leonardo and ensure it successfully appears in the GCP Pub/Sub topics and is processed correctly by any cloud functions available.
- Verify MQTT configurations, IAM Permissions, and any firewall rules that may interfere with data transmission.
Monitor and Maintain the Integration
- Set up monitoring logs and alerts in both SAP Cloud Platform and GCP to track the performance and reliability of your integration, ensuring data is processed and transferred efficiently.
- Regularly review and update security protocols, including token refreshes and certificate management, to maintain the integrity and security of the data flow.
