What is AWS S3 Bucket ?

Amazon Simple Storage Service (Amazon S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance. There are different ways to create an S3 bucket in AWS, let check one by one.

Using the AWS Management Console

This is the most common way to create an S3 bucket.

1. Sign in to the AWS Management Console and open the Amazon S3 console
2. In the left navigation pane, choose Buckets.
3. Choose Create bucket. The Create bucket page opens.
4. For Bucket name, enter a name for your bucket.
5. For Region, choose the AWS Region where you want the bucket to reside.
6. Choose any additional configuration options, such as versioning or encryption, ACLs and control ownership of objects uploaded in your bucket etc.
7. Click the “Create bucket” button to create your new S3 bucket.

Using the AWS Command Line Interface (CLI)

We can also create an S3 bucket using the AWS CLI.

1. Open a terminal or command prompt.
2. Install and configure the AWS CLI.
3. Use the “aws s3 api create-bucket” command to create a new S3 bucket, specifying the bucket name and region.

aws s3api create-bucket --bucket my-new-bucket --region us-west-2

Using AWS SDKs

AWS provides SDKs for various programming languages, which allow you to interact with AWS services programmatically. We can also create an S3 bucket programmatically using one of the AWS SDKs. Here’s an example SDK for Node.js/JavaScript (v3). For other language check S3 bucket using an AWS SDK

import { CreateBucketCommand, S3Client } from "@aws-sdk/client-s3";

const client = new S3Client({});

export const main = async () => {
  const command = new CreateBucketCommand({
    // The name of the bucket. Bucket names are unique and have several other constraints.
    // See https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucketnamingrules.html
    Bucket: "bucket-name",
  });

  try {
    const { Location } = await client.send(command);
    console.log(`Bucket created with location ${Location}`);
  } catch (err) {
    console.error(err);
  }
};

Using AWS Cloud Formation

AWS Cloud Formation is a service that allows you to create and manage AWS resources using templates. We can create an S3 bucket using a Cloud Formation stack using template. To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "Type" : "AWS::S3::Bucket",
  "Properties" : {
      "AccelerateConfiguration" : AccelerateConfiguration,
      "AccessControl" : String,
      "AnalyticsConfigurations" : [ AnalyticsConfiguration, ... ],
      "BucketEncryption" : BucketEncryption,
      "BucketName" : String,
      "CorsConfiguration" : CorsConfiguration,
      "IntelligentTieringConfigurations" : [ IntelligentTieringConfiguration, ... ],
      "InventoryConfigurations" : [ InventoryConfiguration, ... ],
      "LifecycleConfiguration" : LifecycleConfiguration,
      "LoggingConfiguration" : LoggingConfiguration,
      "MetricsConfigurations" : [ MetricsConfiguration, ... ],
      "NotificationConfiguration" : NotificationConfiguration,
      "ObjectLockConfiguration" : ObjectLockConfiguration,
      "ObjectLockEnabled" : Boolean,
      "OwnershipControls" : OwnershipControls,
      "PublicAccessBlockConfiguration" : PublicAccessBlockConfiguration,
      "ReplicationConfiguration" : ReplicationConfiguration,
      "Tags" : [ Tag, ... ],
      "VersioningConfiguration" : VersioningConfiguration,
      "WebsiteConfiguration" : WebsiteConfiguration
    }
}

Using AWS Cloud Shell

AWS Cloud Shell is a browser-based shell environment that we can use to manage AWS resources. We can create an S3 bucket using the AWS CLI in Cloud Shell. Here’s an example:

1. Open AWS CloudShell from the AWS Management Console.
2. Run the following command to create a new S3 bucket:

aws s3 mb s3://bucket-name --region us-west-2

Using AWS Lambda

AWS Lambda is a serverless computing service that allows you to run code without provisioning or managing servers. You can create an AWS Lambda function to create an S3 bucket. Here’s an example in Node.js.

const AWS = require('aws-sdk');
const s3 = new AWS.S3();

exports.handler = async (event, context) => {
  const bucketName = 'my-new-bucket';

  try {
    const response = await s3.createBucket({
      Bucket: bucketName
    }).promise();
    console.log('Bucket created:', bucketName);
  } catch (err) {
    console.error(err);
  }
};

Conclusion

These are some few examples through we can create an S3 bucket in AWS. There are many other methods and tools available, so it’s worth exploring the AWS documentation and resources to find the best approach for your specific use case.
