How to install BigBlueButton on Ubuntu 20.04 LTS Linux

Learn the quick steps to install and configure BigBlueButton on Ubuntu 20.04 LTS Focal Fossa server to create your own web-based video conferencing platform free of cost. 

“BigBlueButton” or “BBB” is an open-source web-based video conferencing tool. This means that users have to enter the URL in the browser instead of downloading the program to their computer. With the free version of “BigBlueButton”, users can conduct video conferences, as well as host webinars and online presentations.

The platform has experienced increased demand, especially due to the corona pandemic and the associated online teaching. Many schools have been using open-source software for some time, enabling students and teachers to communicate. In addition to audio and video transmission, the software also offers a chat and a virtual whiteboard for presentations.

If necessary, the room can also be secured with an access code and the conference can be recorded. To create a conference, you must first register or, if you already have an account, log in. You can then create a room and invite it via a link.

How do I use Big Blue Button?

Once you will have the Invitation link received by the Moderator, open the same in your browser. If an access code is required then supply that. After that press, the Join button and then choose the medium of joining the meeting means whether you want to listen to the conference without a microphone or participate with an active microphone.

How secure is Big Blue Button?

Big Blue Button is an open-source program, so the source code is publicly available to everyone. Hence, nothing is hidden or any malicious code that can create some ruckus.  Schools, Universities, and businesses can set up the software on their own server for more security. This means all data thus remains on your server and – if Big Blue Button is configured correctly – it is only sent encrypted. Nevertheless, the developers of BigBlueButton also offers it as a service that one can subscribe to by paying its usage cost.

What features does Big Blue Button offer?

The software also offers a private and public chat function, a digital whiteboard, and breakout rooms. Here is the list of some important ones:
