Cloud federations and data spaces: Get to know the Simpl project

The European Commission's 'European Data Strategy' states that the creation of a single market for shared data is key. In this strategy, the Commission has set as one of its main objectives the promotion of a data economy in line with European values of self-determination in data sharing (sovereignty), confidentiality, transparency, security and fair competition.

Common data spaces at European level are a fundamental resource in the data strategy because they act as enablers for driving the data economy. Indeed, pooling European data in key sectors, fostering data circulation and creating collective and interoperable data spaces are actions that contribute to the benefit of society.

Although data sharing environments have existed for a long time, the creation of data spaces that guarantee EU values and principles is an issue. Developing enabling legislative initiatives is not only a technological challenge, but also one of coordination among stakeholders, governance, adoption of standards and interoperability.

To address a challenge of this magnitude, the Commission plans to invest close to €8 billion by 2027 in the deployment of Europe's digital transformation. Part of the project includes the promotion of infrastructures, tools, architectures and data sharing mechanisms. For this strategy to succeed, a data space paradigm that is embedded in the industry needs to be developed, based on the fulfilment of European values. This data space paradigm will act as a de facto technology standard and will advance social awareness of the possibilities of data, which will enable the economic return on the investments required to create it.

In order to make the data space paradigm a reality, from the convergence of current initiatives, the European Commission has committed to the development of the Simpl project.

What exactly is Simpl?

Simpl is a €150 million project funded by the European Commission's Digital Europe programme with a three-year implementation period. Its objective is to provide society with middleware for building data ecosystems and cloud infrastructure services that support the European values of data sovereignty, privacy and fair markets.

The Simpl project consists of the delivery of 3 products:

• Simpl-Open: Middleware itself. This is a software solution to create ecosystems of data services (data and application sharing) and cloud infrastructure services (IaaS, PaaS, SaaS, etc). This software must include agents enabling connection to the data space, operational services and brokerage services (catalogue, vocabulary, activity log, etc.). The result should be delivered under an open source licence and an attempt will be made to build an open source community to ensure its evolution.
• Simpl-Labs: Infrastructure for creating test bed environments so that interested users can test the latest version of the software in self-service mode. This environment is primarily intended for data space developers who want to do the appropriate technical testing prior to a deployment.
• Simpl-Live: Deployments of Simpl-open in production environments that will correspond to sectorial spaces contemplated in the Digital Europe programme. In particular, the deployment of data spaces managed by the European Commission itself (Health, Procurement, Language) is envisaged.

The project is practically oriented and aims to deliver results as soon as possible. It is therefore intended that, in addition to supplying the software, the contractor will provide a laboratory service for user testing. The company developing Simpl will also have to adapt the software for the deployment of common European data spaces foreseen in the Digital Europe programme.

The Gaia-X partnership is considered to be the closest in its objectives to the Simpl project, so the outcome of the project should strive for the reuse of the components made available by Gaia-X. 

For its part, the Data Space Support Center, which involves the main European initiatives for the creation of technological frameworks and standards for the construction of data spaces, will have to define the middleware requirements by means of specifications, architectural models and the selection of standards.

Simpl's preparatory work was completed in May 2022, setting out the scope and technical requirements of the project which have been the subject of detail in the currently open contractual process. The tender was launched on 24 February 2023. All information is available on TED eTendering, including how to ask questions about the tendering process. The deadline for applications is 24 April 2023 at 17:00 (Brussels time).

Simpl expects to have a minimum viable platform published in early 2024. In parallel, and as soon as possible, the open test environment (Simpl-Labs) will be made available for interested parties to experiment. This will be followed by the progressive integration of different use cases, helping to tailor Simpl to specific needs, with priority being given to cases otherwise funded under the Europe DIGITAL work programme.

In conclusion, Simpl is the European Commission's commitment to the deployment and interoperability of the different sectoral data space initiatives, ensuring alignment with the specifications and requirements emanating from the Data Space Support Center and, therefore, with the convergence process of the different European initiatives for the construction of data spaces (Gaia-X, IDSA, Fiware, BDVA).
