 Open infrastructure is about openness, diversity, and ultimately about independence. At StackHPC, we work with clients in research computing, often teams with deep technical expertise in the platforms they deploy and maintain. We help those clients with transformation to open infrastructure based around OpenStack. Our vision is for what we call the software-defined supercomputer. We believe this can only be realistically achieved using open infrastructure and the collective effort of institutions around the world to make this great cloud environment. And that is why StackHPC is proud to join the Open Infrastructure Foundation as a founding member.
