Oracle Cloud Infrastructure (OCI) Object Storage

OCI Object Storage is Oracle's enterprise-grade, S3-compatible storage service. It offers strong security defaults, including automatic encryption, customer-managed keys, and immutable object storage to prevent deletion. It integrates with OCI's Identity and Access Management and comprehensive auditing. Part of a larger cloud ecosystem, it suits enterprises with hybrid Oracle databases or applications.

Its tiered storage (standard, infrequent access, archive) provides cost optimization. It ranks as a decent, highly secure option for large enterprises, particularly those invested in or migrating to the Oracle Cloud infrastructure.
