Storage Services: Object, Block, and File Storage Questions

Know the main storage categories. Object Storage (S3, Azure Blob, Cloud Storage) is best for unstructured data, files, backups, and large-scale storage; it's infinitely scalable and cost-effective but accessed by key, not mounted like filesystems. Block Storage (EBS, Managed Disks, Persistent Disks) attaches to VMs; ideal for OS and database storage; provides high performance. File Storage (EFS, Azure Files, Filestore) provides shared access across multiple instances; useful for shared data and collaborative workflows. Understand use cases: Object storage for data lakes and backups; block storage for database disks; file storage for shared application data. Know that object storage pricing is very low compared to other options.
