Implementation plan:

  1. What is object storage — flat namespace for files (blobs)
  2. Comparison: object storage vs database vs filesystem
  3. Use cases: images, documents, backups, large files
  4. Key concepts: buckets, objects, keys (paths)
  5. Public vs private buckets — access control
  6. Interacting with object storage via API: upload and download
  7. Pre-signed URLs — temporary access to private objects
  8. Integrating object storage from a Spring Boot application (brief)
  9. Exercise: upload and retrieve a file from object storage
