What is AWS S3 used for?

There’s no doubt that among the most popular cloud computing platforms, Amazon Web Services (AWS) has risen to the top of the list. Most organizations have already adopted and implemented it, where the remaining is on the verge of doing it. Companies have been transitioning their operations to this cloud storage platform because it allows them to store data and provides a range of other benefits. Data access has become much easier as a result, and all credit goes to the Internet, which allows businesses to do so from anywhere at any time. Professionals who have the AWS certification are among the most in-demand in the different industries today.

But then the question arises what is AWS ? Do you have any idea about it? If no, then this article might be a great help to you. Describing the AWS S3 , this article thus primarily focuses on what this AWS is and what it is used for. So, let’s have a look.

About Amazon Web Services

AWS is known as the leading cloud provider present in the market and provides nearly over 170 AWS services to developers so that professionals can access data from anywhere at any place. It is an online platform that offers cloud computing solutions to professionals and organizations that are both scalable and cost-effective. AWS is a widely used cloud platform that helps businesses develop and expand by providing on-demand services like database storage, computational power, and content delivery.

What is AWS S3?

AWS S3 is a service for storage offered by Amazon. It represents for ‘simple storage service’ and provides cloud storage for only several web development applications. To offer the storage, S3 makes use of publicly available web interfaces like REST, SOAP, and BitTorrent. The S3 has been designed with converged infrastructure. The necessary storage capacity should be expandable. As a result, Amazon has developed it into several storage tiers, putting much emphasis on consumers who require more cloud storage.

The Amazon S3 provides file storage through a web interface. It is built to store, secure and retrieve any data from “buckets” at any time on any device from anywhere. As this storage service describes, an S3 environment has a flat structure. Here a user can create a bucket and this bucket thus helps to store objects in the cloud system.

Features of AWS S3

The most prominent features that this storage service has included:

  • Durability: The service claims to have a durability of 99.999999999%. This proves that the chance of losing any data can be one in a billion. 
  • Availability: The uptime of Amazon Web Services S3 ensures about 99.99% standard access.
  • Server-side Encryption (SSE): Supports three SSE models that are SSE-S3, SSE-C, and SSE-KMS.
  • File Size Support: Files ranging from 0 bytes to 5 terabytes can be stored easily. 
  • Infinite Storage Space: Having infinite storage space makes it more scalable for every kind of use case.
  • Pay as you see: Users are charged as per their storage holding.
  • AWS-S3: It is region-specific.

Why use Amazon Web Services S3?

The AWS S3 service is available to businesses that are of varied sizes and belong to different sectors. Data backups, websites, archiving, mobile apps, restores, IoT devices, and corporate apps are just a few examples of the use cases. The S3 is a storage device that can hold files up to 5 terabytes. The data file is subsequently saved in a bucket which is eventually connected to the account of Amazon Web Services. Because all of the objects or files are stored in a bucket linked with a single AWS account, each user may be given a unique key to identify themselves.

The objects, as well as the bucket, maybe moved in the direction of the user. The bucket’s permissions may also be modified, allowing users to upload, download, and so on. When there are numerous users, this helps by limiting the access power. S3 reduces the risk of faulty or incomplete data writes while implementing a data inconsistency across the board. The same goes for the process of deletion of data as well. 

Who can use AWS S3?

Any Solutions architect after his or her deployment can add AWS S3 into the solution architecture and instruct the DevOps team so that they can utilize it for storing data.

Where can you use AWS S3?

AWS S3 may be used to protect and restrict data access in a project that creates and has access to large amounts of sensitive data. Downtime is not an option because the breadth of these projects is often viewed at the enterprise level.


One might find a lot of alternatives to AWS S3 like Openstack Swift or Microsoft Azure. All they differ in terms of usability and feature set only. Other than that, instructions of OVERWRITE/GET/PUT are also not in common. For issues of latencies and optimization, one may select cloud storage that eventually is based on the infrastructure currently in place. When utilizing AWS S3, other services such as Amazon Elastic Compute Cloud, Amazon EMR, and AWS Snowball are typically available.
