Advanced Version Introduction

  • Kyma ✅
  • Cloud Foundry ✅

The Advanced Version of the sample application requires a certain Basic setup, which means you have to get started with the Basic Version, before challenging yourself with the Advanced Version. The Expert Features contain additional components and tutorials that can be applied to both the Basic and Advanced Version.

In the Basic Version we provided you with the core elements required for a Cloud Foundry or Kyma-based Software as a Service (SaaS) application on SAP Business Technology Platform (SAP BTP). The idea of the Advanced Version is about taking all the features implemented in the Basic Version and extending them to the next level with other great services provided by SAP BTP. This will take you one step closer to an enterprise-read SaaS application

Take a look at the following architectures to get an idea of the Advanced Version in the Kyma and Cloud Foundry Runtime.

2. Included Features

The Advanced Version provides the sample implementation of a CAP-based multitenant SaaS application containing all the features of the Basic Version. Furthermore, the Advanced Version provides sample integrations and usage scenarios of SAP BTP services including:

(*) indicates that the feature is only available in the Advanced Version, all other features are also available in Basic Version.

    • (*) SAP API Management setup which allows SaaS Providers to add enterprise API qualities to the API endpoints provided to subscribers.

3. Advanced Version Result

As a result of this Advanced tutorial, you have a SaaS application running in the Cloud Foundry environment or Kyma Cluster of your own SAP BTP Subaccount.

(*) indicates that the feature is only available in the Advanced Version, all other features are also available in Basic Version.

  • offers your Subscriber Tenants a user interface to
    • manage the Tenant specific users of the SaaS application.
    • create projects and assign members to different projects.
