OSCON (Open Source Convention) has been the focal point of the open source movement. The inception of OSCON came from an event focused on Perl and grew to cover the other scripting languages. It has since evolved into the destination for all things free and open. The event has also provided a platform for the launch of major initiatives such as Kubernetes 1.0 and OpenStack—both announced at OSCON.
