Open source is everywhere, in every product, every business, and every organization -- it’s a core part of the modern DevOps landscape. Understanding your open source engagement enables you to drive the outcomes you want, from creating great ecosystems around your tech, to contributing to and supporting the projects you depend on, to using open source in a secure and compliant way. This is the remit of the modern Open Source Programs Office (OSPO).

Not only is open source in 80-90% of today’s systems, the scale of that open source is staggering -- it’s trivial to type docker build and end up with 100s or 1000s of components in your container.

In this talk we cover the policies, mechanisms, and culture changes needed to be effective as you attempt to navigate the scope and scale of open source engagement, enable your organizations, and ensure important ecosystems flourish. We tell the story through the lens of Microsoft’s journey from actively opposing open source to being one of its largest proponents with over 20,000 developers on GitHub. You will hear how Microsoft evolved, and continues to evolve, on the engagement spectrum and learn how you can drive similar changes in your world.
