Object storage is a type of cloud storage that stores data as discrete units called objects. Each object has a unique identifier, metadata, and data. Object storage is ideal for storing long-term archive data in the cloud because it offers high scalability, durability, availability, and cost-effectiveness12. Object storage can handle large amounts of unstructured data, such as documents, images, videos, and backups, and allows users to access them from anywhere using a simple web interface3. Object storage also supports features such as encryption, versioning, lifecycle management, and replication to ensure the security and integrity of the archive data45. References: [CompTIA Cloud Essentials+ Certification Study Guide, Second Edition (Exam CLO-002)], Chapter 2: Cloud Computing Concepts, pages 36-37.
