AWS S3 storage is a cloud storage service offered by Amazon. It is a great way to store large amounts of data, and it is very reliable. It is also a great way to back up your data.
An S3 bucket is a container for storing objects (files and folders) in AWS S3. Buckets can be used to store data from different applications or to store data for backup and disaster recovery purposes. You can create as many buckets as you need, and you can choose the region where your buckets are stored.
