Aruba Cloud vs OpenStack Barbican

Both stand on cloud infrastructure as a service (cloud iaas) software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

Barbican offers OpenStack-native secret management with configurable storage integrations, including HSM support. Operators should account for its default key-storage tradeoff and the limits on container ACLs.
