Hyrax utilizes the Samvera framework to provide users with a base-level IR solution that can be customized, allowing for easier upgrades and better sustainability as the users are not working with an entirely home-grown DAMS or IR. HyKu is a multi-tenant version of Hyrax that allows for an organization to host multiple instances of Hyrax at scale - example: A vendor could use HyKu to run a single instance which would be home to multiple customers utilizing the same Fedora, Valkyrie and core components but display entirely locally with local control for customers. Sufia is a predecessor of Hyrax - and while it continues to exist at some institutions, Hyrax is a combination of Sufia, Curation Concerns 
and original development work from the Samvera community.

- My institution/organisation is moving more and more stuff into the cloud. Can I have Samvera in the cloud?
Hyku was created specifically to work in the cloud as a multi-tenanted solution for delivering repository solutions. There is a Hyku Interest Group that is taking forward the development of Hyku for use in this context.
- Does Samvera meet good standards of accessibility/security/...?
The Hyrax gem, which is the basis of most Samvera systems at the moment, has undergone an external accessibility audit. A few minor issues were found which are currently being addressed. - How stable is the code?
The code is being actively developed on an ongoing basis, but is also being released in managed ways. Hyrax has a roadmap that highlights ongoing development and likely release schedule; individual gems have component owners who announce new releases periodically.
- Who else is using it? and how?
There is a list of sites using Samvera at https://samvera.org/samvera-partners/ ? (this needs updating with more links)
