Use cases

Open source software for the public sector

Univention develops open-source software and supports IT modernization in the public sector, in education, and in companies with its applications. Due to its own extensive infrastructure, which had grown over the years, Univention’s growth recently seemed to be in jeopardy, as there was an increasing lack of in-depth know-how and time to deal intensively with the necessary topics. For this reason, the company was looking for an open-source cloud that offered more scalability, greater reliability, and SCS compatibility. With pluscloud open, Univention can relieve its own internal IT and concentrate on further growth.

Performance & security without technology lock-in

The start-up company Knowledge Hero aims to revolutionize the learning of PLU codes (price look-up codes) in food retail with its SaaS learning solution easyPLU®, which was launched at the end of 2023. As the solution has to ensure simultaneous learning processes for a large number of users and constantly process large amounts of live data, the start-up was looking for a suitable infrastructure on which it could develop and operate its software in the long term. Above all, the infrastructure had to guarantee data security and performance. Knowledge Hero chose plusserver’s Managed Kubernetes solution because easyPLU® is based on a modern microservice architecture. The secure infrastructure from certified data centers in Germany was also a decisive factor. Thanks to the BSI-C5-tested pluscloud open, on which the plusserver Kubernetes Engine is based, Knowledge Hero can run its workloads securely and with high performance without having to rely on proprietary technologies. This solution is therefore the ideal foundation for long-term, flexible growth without technology lock-in.

Customer Testimonials

Stefan Gohmann von Univention
“We used to do a lot of things ourselves. But lately, we have not been able to deepen the expertise we need to scale. And that meant that any downtime would be very expensive. So we looked for an open source cloud that could give us data sovereignty and SCS compatibility, and we found it in pluscloud open.”
Stefan Gohmann
COO of Univention
Andreas Weiss:

With Gaia-X Federation Services we offer important building blocks for the operation of Gaia-X ecosystems. This also includes the presentation of specific applications in operation. For this purpose, we use the sovereign cloud stack offering from plusserver – the pluscloud open.
