18. Summary

19. So, what does a platform mean nowadays?
The Ellip Solutions are built for earth sciences
practitioners:
▪ to share about their findings, streamline
their creation of new resources and make
these accessible, interoperable,
▪ and document their developments on the PaaS
as reproducible experiments
In line with the FAIR guiding principles to make
data findable, accessible, interoperable and
reusable

20. All of it: an Open Cloud strategy
▪ The Ellip subscribers remain the owners of
their created assets, and decide how to
share these on the platform, for other users
to find and reuse these assets.
▪ They are also empowered to decide on the
target production environment of their
packaged applications (no lock in with
Cloud provider)
Producers
Consumers

21. Looking forward
hearing from you!
