AWS S3 Bucket is a storage container that can store data. It’s an easy way to upload, download, and share files. There are no limits on how long the content stays in the bucket or how big it can be. It’s designed for long-term archiving and backup, and it can scale up or down as needed. You can also use this service with Amazon EFS (Elastic File transfer), which allows you to create an NFS mount point within your VPC. It is beneficial if you need access to your data from outside the region it resides.

What are the primary purposes of AWS S3 Bucket?

There are several types of the bucket to choose from. Some buckets formats read-only, others read-write, but all can be used as a download or upload medium. However, all of them are designed for Storage and data transfer to/from any other location on the services provided by Amazon Web Services.


In S3, files are stored in buckets. Buckets are similar to folders on your computer. the common name given to objects under S3 (simple storage service).

An object can be anything. A photo, a zip file, a movie, or even something as familiar as a text file. When you see an object within the S3 bucket, it is nothing more than a pointer that points to its location.

S3 Storage Types

There are three types of S3 Storage: –

Standard Storage – The default type of Storage on AWS. Standard offers durability and availability by storing objects on multiple devices across multiple facilities. And it’s available for all regions and will automatically replicate to other AWS Availability Zones (AZ). It is designed to offer 99.99% durability.

Reduced Redundancy Storage (RRS) is designed for data that can be recreated when needed. However, RRS doesn’t provide the same availability and durability that S3 Standard offers to store these objects. When using RRS, you will incur fewer charges than Standard because it keeps your data in only one AZ rather than multiple.

Glacier is designed for long-term archiving and offers a shallow cost storage option because it requires no administration. You pay only for what you use, there is no additional cost to transfer your data to S3 IA (IA), but the main drawback of the IA is that you need to wait 3-5 hours before you can access it.

Objectives of Glacier:

  1. Low-cost Storage.
  2. Low-latency retrievals.
  3. Secure and safe for customers.
  4. Designed to store infrequently accessed data and long-term returns.

Infrequent Access (IA) is different from RRS because it’s designed for files accessed monthly or annual rather than daily. Most organizations using IA store the long-term data that they need to archive. Therefore, you can still expect S3 Standard durability with RRS.

The difference between Standard and RRS is the level of redundancy, not durability or cost.

What’s the difference between S3 Standard and S3 IA?

The main difference is the duration of access. Although AWS does not mention it, you could consider S3 IA storage as an object archiving service. You can also use IA for rarely accessed objects like data backup. When using IA, things are automatically transitioned to Glacier after 90 days, becoming Glacier’s responsibility.
