When high availability and keeping sensitive information safe are top priority Scality is a great option and has good features that make it ideal for these type of applications. For small companies with limited resources to administer extensive systems Scality would not be a good match. It takes people dedicated to this platform to keep it functioning at its best.
Some access settings are mutually exclusive for performance (REST vs. CIFS)
QoS by Tenant requires use of external ADC (Hitachi suggested and sold us Pulse Secure) and their support on this product offering is not up to their normally high standard
As an organization, it took us a while to understand the shift from a traditional black box SAN to software-defined storage, but now we are much more certain of what this means. The time invested and the resources were not very high, thanks on the one hand to the technical support and on the other to the coherence and good development of the platform.
[Hitachi Content Platform (HCP)] has all of the features of competitive offerings and wraps them in a better multi-tenancy solution. It's object level permission model and non-overridable immutability (in Compliance mode for configured namespaces) is a bump up compared to other solutions. It's offering of it's own API as well as S3 REST support make it very flexible.
In reality, it did not become a substitute for AWS, since it allowed us to maintain a much more compact and rigid system by taking advantage of the support and evolutionary trend that Scality has and keeping AWS as a leader.
