Object Storage

"File storage" is what you're already familiar with:

• Files are stored in a hierarchy of directories
• A file's system-level metadata (like timestamp and permissions) is managed by the file system, not the file itself

File storage is great for single-machine-use (like your laptop), but it doesn't distribute well across many servers. It's optimized for low-latency access to a small number of files on a single machine.

Object storage is designed to be more scalable, available, and durable than file storage because it can be easily distributed across many machines:

• Objects are stored in a flat namespace (no directories)
• An object's metadata is stored with the object itself

1. Open the video object we uploaded in the last lesson in the S3 console and look at the "Object overview" - you should see a bunch of metadata about the object:
   • Size
   • Type
   • Entity tag
   • etc.
2. Use the AWS CLI to read the metadata of your uploaded vertical video object, and redirect the output to /tmp/object_metadata.txt

aws s3api head-object --bucket BUCKET_NAME --key OBJECT_KEY > /tmp/object_metadata.txt

Replace BUCKET_NAME and OBJECT_KEY with the name of your bucket and the key of your object

Run and submit the CLI tests.
