Abstract: Cloud storage provides accessible interfaces, near-instant elasticity, scalability, multi-tenancy, and metered resources in a distributed framework providing fault tolerant solutions with high data durability.

Further, many retention structures are user driven but users make mistakes requiring a change to the record's associated retention period. Retention period mechanism enforced with immutable storage can satisfy compliance requirements but run contrary to data privacy rules as well as blocking adjustments.
