Kronos Edition

Kronos Edition provides a compatible environment for SAP HANA Extended Application Services (XS) based applications. It is deployed outside of SAP HANA instance as a Docker a container on Kubernetes. Hence, some of the features can work against any other JDBC compliant RDBMS such as PostgreSQL. The compatibility stack is an extension of the Eclipse Dirigible cloud development platform.

This is the official fork of the Project “XSK”, which was discontinued by SAP in 2022.

Landscapes - Before and After Migration

The main difference is that the engine running the application is now outside HANA instance, hence it is possible to run it for scale on any Kubernetes or Containers as a Service offering - SAP or non-SAP.

FAQ

  • How long will Kronos be supported?

    Kronos is an open source project with community support. Everyone can join and make a PR. In fact SAP discontinued official support to project “XSK”, and this fork maintained by the same developers is prove that the approach is viable and useful. The company codbex provide enterprise support for Kronos based runtimes.

  • Should future developments be based on Kronos?

    Yes, you can use Kronos for future development.

  • What about the tooling? Do we get state of the art tooling for maintaining and enhancing Kronos?

    Kronos tooling is based on Eclipse Dirigible and in the near future it will be possible to maintain Kronos projects with any modern IDE like VSCode, Eclipse Theia, etc.

  • What about the ops aspects - will Kronos be smoothly integrated into a state-of-the-art lifecycle and ops management (be it SAP-based or non-SAP based like GitHub Actions?

    Yes, the Kronos itself uses GitHub actions for CI/CD

  • Will there be limitations that will not be mitigated?

    You can get the up-to-date list of covered features as well as the limitations, cheat sheet and readiness.
