4. Enter a unique bucket name and select the region where you want to create the bucket.

5. Choose the desired options for access control and versioning.

6. Click the "Create Bucket" button

Once you have created an S3 bucket, you can upload files to the bucket using the S3 web console, AWS CLI, or SDKs.

Here are the steps to upload a file using the S3 web console:

1. Navigate to the S3 service.

2. Click on the bucket you created.

3. Click the "Upload" button.

Here are the steps to set up access controls in Amazon S3:

1. Navigate to the S3 service.

2. Click on the bucket that contains the object you want to set up access controls for.
