Step-by-Step Example: Creating an S3 Bucket and Uploading an Object

Log in to the AWS Management Console: Go to the AWS Management Console and sign in with your AWS credentials.

Open the S3 Console: Search for “S3” in the search bar and open the S3 console.

Create a Bucket:

• Click “Create bucket.”
• Enter a unique bucket name (bucket names must be globally unique).
• Select a region (e.g., us-east-1).
• Configure other settings as needed (e.g., versioning, encryption).
• Click “Create bucket.”

Upload an Object:

• Navigate to the newly created bucket.
• Click “Upload.”
• Select the file you want to upload.
• Configure upload settings (e.g., object key, storage class).
• Click “Upload.”

Verify the Upload:

• Refresh the bucket view.
• Verify that the uploaded object is listed in the bucket.

Key Concepts:

• Bucket: A container for storing objects in S3.
• Object: A single file or data stream stored in an S3 bucket.
• Object Key: A unique identifier for an object within a bucket.
• Storage Class: Determines the storage location and cost of storing objects (e.g., Standard, Standard-IA, Glacier).
• Versioning: Enables you to keep multiple versions of the same object.
• Access Control Lists (ACLs): Control access to objects within a bucket.
• Bucket Policies: JSON-based rules that control access to a bucket and its objects.
