GC Tech-Talk #5

27. Oktober 2022 | 14:00 - 15:00

GC Tech-Talks | Florian Bühr | HPE & Sönke Pingel | EnBW Cyber Security GmbH

Join our monthly GC Tech-Talks, an open platform for the sharing of innovative projects related to sustainable Cloud infrastructures, Cloud services and Cloud use cases!

Hard facts

27 October, 2022

(And for the upcoming tech-talks every last Thursday of the month, from 2:00 pm to 3:00 pm)

NEW! We have adjusted our tech-talk and will now have one presentation per session instead of two. This will give the participants and our speakers more time for discussions and deep dives. We will also share news and events that could be of interest to our community.

    „Share without sharing – Swarm Learning to analyze any private data from any data owner without sharing private data to foster sovereignty“  Creating value from data which is inherently private and captured in  siloes needs to consider a multi-dimensional, open, transparent,  compliant, trustworthy and explainable approach. Swarm learning, a  decentralized machine-learning approach, unites edge computing,  blockchain-based peer-to-peer networking and coordination while  maintaining confidentiality without the need for a central coordinator,  going beyond federated learning. This enables to leave the data owner to  be sovereign on his data without exposing it in  the network. As an example in the medical field, it already has been  used successfully to perform secure decentralized patient classification  in several diseases using different data types. It extracts the  information and knowledge from the data to provide  doctors a valuable tool to help cure their patients.

    „Basic digital service – a utility perspective“

    Today, basic IT is a vital infrastructure for society. It is similar to and based on electricity and telecommunication, the core assets of utilities, so that many utilities already offer data center and IT solutions. In the near future, basic IT needs to become more EU-sovereign, green, secure, with low latency and cloud-ready – in different shadings for different business needs. In an R&D study @EnBW we evaluate with partners potential opportunities for such a distributed basic digital infrastructure. More information:

What is the focus of the GC Tech-Talks?

The GC Tech-Talks focus on projects that have the potential to improve digital infrastructures and cloud services, as well as on the use cases that rely on these infrastructures and services. Interesting topics include, but are not limited to:

  • Concepts, technologies or prototypical implementations that improve the sustainability of cloud infrastructures and services
  • Concepts or technologies to achieve interoperability, security, scalability and openness of cloud services in Multi-Cloud setting
  • Initial implementation and prototypes of the concepts that are being jointly developed in communities such as Gaia-X
  • Use cases that rely on Cloud services

Who can participate in the meetings?

Anyone who is interested in the discussed topics.

Who can present a project in the meetings?

Anyone who has a potentially relevant contribution to the community. The presentations can focus on projects in different maturity stages and should include technical aspects (i.e.: an initial technical concept or an overview of the implementation). Since the Tech-Talks are open, all speakers should use discretion regarding the disclosure of confidential information.

The story behind the GC Tech-Talk

In the summer of 2021, 28 partners joined forces to submit a project proposal to the call for expressions of interest for the IPCEI-CIS (Important Project of Common European Interest on Cloud Infrastructure and Services). The proposal was submitted under the name GREEN-CIS (General Purpose Resilient and Secure Energy Efficient Computing Infrastructure Network) and focused on developing and building a virtual, sustainable Cloud-Edge system for Europe, based on a decentralized, multi-provider open-source ecosystem that can operate as a seamless unit. Not all partners made it through the pre-selection process, but they still share the vision of an open, sustainable future of the Cloud infrastructure and services. The GREEN-CIS Tech-Talks were devised as an open community to continue driving this vision forward and to lay the grounds for an innovative and collaborative ecosystem for joint projects.
