BitNami Open Atrium provides all-in-one free native installers, virtual machines and Cloud Images that simplify the Open Atrium installation and hosting. The stacks include a pre-configured version of Open Atrium and all of its required dependencies. Open Atrium is an open source platform designed specifically to make great teams communicate better. An intranet in a box with: a blog, a wiki, a calendar, to do list, a shoutbox, and a dashboard to manage it all. Let's not forget that it's also completely customizable. BitNami Stacks are built with one goal in mind to make it as easy as possible to install open source software. Our installers completely automate the process of installing and configuring all of the software included in each Stack, so you can have everything up and running in just a few clicks. BitNami Stacks are completely self-contained, and therefore do not interfere with any software already installed on your system.
