What is amazon s3?

Amazon s3 or simple storage system is storage service by aws.
Here files are stored as objects.
Objects are stored in buckets. so we need to create buckets first and then store objects inside it.
we can assign the accessibility (ACL) to objects as private or public.
public objects will be accessible to all.
Private objects require access key and a secret key.

Any amount of data can be transferred with s3 storage.
