After several years of intensive planning and implementation work, the network renewal at RWTH Aachen University is approaching an important milestone: Since its launch in 2018, the finish line for the end of 2026 is slowly coming into view. You can also read about our interim status in 2022 in our previous blog article. The completion of the measures in the individual university buildings marks the transition from project to regular operation. The aim of the network renewal is to modernize the communication infrastructure, which is in some parts severely outdated, and to put it on a future-proof footing—technically, organizationally, and operationally.

Artificial intelligence (AI) is no longer a topic for the future – it has arrived in the centre of society and is changing the way we research, learn and work. As one of Europe’s leading technical universities, it is therefore crucial for RWTH Aachen University to actively engage with the potential and challenges of this technology.
As RWTH’s central IT facility, the IT Center plays a central role in this: it develops technical solutions, ensures a data protection-compliant infrastructure and creates new services that enable the use of AI in the university context.
And not just since yesterday: For some time now, the IT Center has been working intensively on making artificial intelligence usable for the entire university.

This year, 13 sessions took place, covering three main topics: the development of new features, the management of old data and the possibility of connecting ILIAS and Moodle with external platforms and tools.
RWTH, May We Introduce: git.nrw
A new service is now available to employees and students in pilot operation: git.nrw!
The associated git.nrw project was launched to provide a central platform to facilitate the exchange of code and ideas between developers, students, and teachers. The aim of the project is to provide a shared central GitLab instance for all universities in North Rhine-Westphalia to facilitate cross-institutional work.
The technical requirements have now been met to gradually open up the instance. RWTH is one of the first universities in North Rhine-Westphalia to be allowed to use the platform. Other universities will be connected step by step.
Find out what the git.nrw service can do and how you can use it for your everyday tasks in the blog post.
Green HPC: Sustainability in the Data Centers of Tomorrow
Digital technologies have become an integral part of science and industry – but data centers are among the biggest energy consumers in the IT sector. High-performance computers in particular are essential for complex calculations in research, but at the same time cause high electricity costs and CO2 emissions. To meet these challenges, RWTH Aachen University is focusing on innovative solutions for energy efficiency and sustainable resource utilisation.
