Good question and very relative nowadays. You should have a look at ILIAS. It’s been developed by German universities. However, it’s very versatile and pluggable. As a company we are offering several integrations. ILIAS is very strong when it comes to collaboration, but it doesn’t offer video conferences out of the box. Actually, I also don’t see ILIAS in that position. For such requirements you should definitely have a look at other solutions like MS Teams, Zoom etc. just because of scalability. Here in Germany mentioned solutions aren’t allowed because of privacy concerns. However, there are open source solutions followed by a system offered by the state for schools and other educational instances.
