Open source software serves as the bedrock for today’s modern software development ecosystem. Tens of thousands of open source projects are continuously improved, with security and performance updates that ultimately deliver better software for developers to leverage. Despite this, too many users can’t take full advantage of open source software because of systemic supply chain challenges with the traditional snapshot-the-world distribution (distro) model. These shortcomings cost the users and organizations who rely on open source time and energy, while threatening their security and ability to innovate.
