How To Store Data in a S3 Bucket? (original) (raw)
Last Updated : 23 Jul, 2025
Pre-requisite: S3 (Simple Storage Service)
AWS S3(Simple Storage Service) is a storage-as-a-service platform provided by Amazon. S3 offers various types of storage classes such as Standard, Standard IA, Intelligent, Reduced Redundancy, and Glacier. Amazon S3 stores the data inside a bucket in the form of an object. The object inside the S3 bucket can be accessed, versioned, and deleted as per requirement. We can store data in S3 using various methods such as below.
Methods to Store Data in S3
- AWS Console: We can access S3 service using a web-based AWS console. We can upload and store files as objects in an S3 bucket using web UI.
- AWS CLI: AWS Command line interface uses various commands which can be used to store and retrieved objects in an S3 bucket.
- AWS SDK: Storing objects to an S3 bucket is also available with the help of programming language-specific SDKs provided by AWS. We can easily import AWS SDK and use it to store application files in S3.
- AWS S3 Rest APIs: S3 provides a REST application programming interface for accessing S3 buckets using Amazon S3 endpoints. The S3 bucket can be accessed with help of standard HTTP and HTTPS requests.
As all other methods need some understanding of other concepts let's see storing data to S3 using AWS Console.
Steps to Store Data to S3 using AWS Console
Step 1: First We need to create an S3 bucket in AWS. To create a bucket navigate to Services > Storage >S3 > Buckets
Step 2: On the S3 page select Create Bucket.

| Block public access | You can allow public access or block it |
| Bucket Versioning | If enabled all objects will be versioned |
| Tags | Optional |
