To improve the quality of its work, create new opportunities and increase its competitiveness, HKV needed easy access to an environment with a pre-installed and validated version of Delft3D version that could scale to available hardware resources in a flexible way depending on the application, for example, risk analysis with large ensemble simulations or highly detailed modelling of structures. Delft3D as a Service (DaaS) is intended precisely for SMEs like HKV. The objective was to have a pilot version of DaaS running for remote use by HKV. With this pilot version, HKV would be able to perform production work with a certified Delft3D version on (HPC, Cloud) hardware. The development of such a pilot version was the challenge facing this experiment.
The official Deltares version of Delft3D has been installed at the HPC systems of SURFsara. This version was certified with an extensive test bench. Such certification is crucial for SME end-users who need to work with the Delft3D software for their clients. A portal for DaaS has been developed. Access is via a command-line interface with more options and flexibility for experienced users and via a web-based interface for inexperienced users. Iterative refinement of the portal was based on beta testing by HKV. Delft3D has been optimized for large-scale HPC. This is needed for coupled modelling involving different Delft3D modules and for highly detailed modelling increasingly required by SMEs. For this, simulations with Delft3D models of the Elbe, Lake Marken, the North Sea and the Amsterdam-Rhine Canal have been used. The objective was to show with these cases the potential of DaaS available to SME end-users.
DaaS opens new possibilities for SMEs, such as HKV, because it offers quick, efficient, and flexible access to HPC hardware resources for modelling and simulation using Delft3D. This Fortissimo experiment served as a starting point for gradual transition for current Delft3D users and growth model for new Delft3D users worldwide. Deltares and HKV themselves are already involved in further projects using Delft3D running on remote HPC systems.
Deltares expects additional revenues of about €70K per annum due to an increase in the use of (certified) Delft3D and of about €500K per annum due to an increase in Delft3D-related advisory and research projects by Deltares itself. With DaaS, Deltares expects an increase of business opportunities in data and forecasting services based on Delft3D and projects related to large scale computing with Delft3D, for example for dike safety assessments.
Due to the new possibilities of DaaS for large ensemble modelling and highly detailed modeling, HKV expects additional revenues of about €100K and €30K per annum, respectively. With DaaS, HKV expects an increase of business opportunities in add-on services based on Delft3D. Furthermore, DaaS will reduce risks in projects with a lot of Delft3D modelling, with the opportunity to spend more project time on creating added value for the client.
As a result of the use of DaaS, the increased revenue from the provision of additional computer resources by SURFsara is expected to be around €120K per annum.
It is planned to make DaaS available as a service not only via HPC systems at SURFsara, but also more widely through the Fortissimo Marketplace.
