'''BigBlueButton''' is an [[open source]] [[web conferencing]] system developed primarily for distance education.

== Features ==
BigBlueButton supports multiple audio and video sharing, presentations with extended whiteboard capabilities - such as a pointer, zooming and drawing - public and private chat, desktop sharing, integrated VoIP using [[FreeSWITCH]], and support for presentation of PDF documents and Microsoft Office documents. Moreover, users may enter the conference in one of two roles: viewer or moderator.

As a viewer, a user may join the voice conference, share their webcam, raise their hand, and chat with others. As a moderator, a user may mute/unmute others, eject any user from the session, and make any user the current presenter. The presenter may upload slides and control the presentation.<ref name="bigbluebuttonorg">

Although its components are open source, the BigBlueButton client depends on a [[browser plugin]] for the [[Adobe Flash]] platform. The BigBlueButton server runs on Ubuntu 10.04 32-bit or 64-bit and can be installed either from source code or from Ubuntu packages. BigBlueButton is also downloadable as a Virtual Machine (VM) that runs within [[VMware Player]] on PC and Unix computers and within [[VMWare Fusion]] on Macs.<ref name="bigbluebutton_install_vm">

</ref>  The BigBlueButton server can also run within a cloud environment, such as Amazon EC2, by installing it on an Ubuntu 10.04 32-bit or 64-bit instance.

== Architecture ==
Similar to [[Openmeetings]], BigBlueButton uses red5, an open source implementation of Adobe's Flash Media Server, to support its real-time collaboration.<ref name="osflashorg"> It also leverages [[redis]], the open-source key-value data store software, to maintain an internal list of its meetings, attendees, and any other relevant information.

In 2010 the core developers added a whiteboard for annotating the uploaded presentation. Jeremy Thomerson added an application programming interface (API) which the BigBlueButton community subsequently used to integrate with [[Sakai]],<ref name="sakaiprojectorg">
