A Step-by-Step Guide to Creating an S3 Bucket in AWS Cloud

30 Jun 2024

Amazon Simple Storage Service (Amazon S3) is a scalable object storage service that allows you to store and retrieve any amount of data from anywhere on the web. Creating an S3 bucket in AWS (Amazon Web Services) is a straightforward process that involves a few simple steps. This guide will walk you through the process of creating an S3 bucket using the AWS Management Console.

Step-by-Step Guide:

1. Sign in to the AWS Management Console:

Navigate to AWS Management Console, and sign in using your credentials.

2. Open the S3 Console:

Once logged in, find and select "S3" from the list of AWS services. Alternatively, you can click here to go directly to the S3 console.

3. Create a New Bucket:

In the S3 console, click on the "Create bucket" button. This will start the process of creating a new S3 bucket.

4. Configure Bucket Properties:

Bucket Name: Choose a unique name for your bucket. Bucket names must be globally unique across all of AWS.

Naming Conventions: Follow AWS naming conventions for S3 bucket names. They should be DNS-compliant and unique; avoid the use of capital letters.

Region: Select the AWS region where you want your bucket to be located. This choice can affect latency and compliance regulations.

Configure options: You can set options like versioning, logging, and tagging for your bucket. These configurations are optional but can enhance your management and security.

5. Set Permissions:

Choose who can access your bucket and the objects within it. By default, only the bucket owner has access, but you can configure more granular permissions using Access Control Lists (ACLs) and Bucket Policies.

6. Review and Create:

Review all the configurations you have chosen for your bucket. Ensure that the settings align with your requirements.

Click "Create bucket" to finalize and create your new S3 bucket.

7. Access Your Bucket:

Once the bucket is created, you can start uploading objects to it using the AWS Management Console, AWS SDKs, or AWS CLI (Command Line Interface).

‘Object’ tab:

In Amazon S3 (Simple Storage Service), the "object tab" typically refers to the list of objects (files or data) stored within a specific S3 bucket. When you navigate to a bucket in the AWS Management Console or interact with it programmatically, you can view or manage the objects stored within that bucket. This tab or section displays details such as object names, sizes, timestamps, and other metadata associated with each object. It's a fundamental part of managing and accessing data stored in S3 buckets.

‘Properties’ tab: Accessing and managing these properties from the Properties tab in the AWS Management Console allows you to configure your S3 bucket according to your specific requirements, ensuring security, compliance, performance, and cost-effectiveness for your storage needs.

‘Permissions’ tab: Managing permissions effectively ensures that your S3 buckets and objects are secure and accessible only to authorized users and applications. It’s essential to configure permissions based on the principle of least privilege, granting only the minimum permissions necessary for users and applications to perform their required tasks.

To manage media files in an S3 bucket using your program while ensuring that the "Block all public access" setting remains unchecked in development but enforced in production, you would typically handle this through AWS IAM policies and possibly S3 bucket policies.

In your development environment, you may want to allow broader access to facilitate testing and development. You can achieve this by defining an IAM policy that grants necessary permissions to your IAM users or roles. Here’s an example policy that grants full access to an S3 bucket and its objects.

Cross-Origin Resource Sharing (CORS) is a security feature implemented by web browsers that allows a web application running at one origin (domain) to access resources from a different origin. An origin is defined by the combination of scheme (protocol), host, and port of a URL.

‘Metrics’ tab: You can configure S3 to collect and report metrics on the bucket and object-level activity, such as the number of requests, data transfer size, and storage metrics. These metrics help you monitor the performance and usage of your S3 resources.

‘Management’ tab: The Management tab in Amazon S3 consolidates these features and settings in one place, making it easier for you to optimize storage costs, manage data lifecycle, ensure compliance, and monitor usage and performance metrics for your S3 buckets and objects.

‘Access Points’ tab: Access points provide a simplified and secure way to manage access to your S3 data, especially in scenarios where you need to segregate access based on different applications, teams, or security requirements. They help simplify access management by encapsulating permissions within the access point configuration, reducing the complexity of managing access controls at the bucket level.

You can start managing your media files in AWS cloud storage by uploading directly or through your program.

Every file contains an object URL that can be used on your site for end users.


Security: Always apply the principle of least privilege when configuring bucket permissions.

Monitoring and Management: Utilize AWS CloudWatch to monitor your S3 bucket metrics, and set up alerts for any unusual activity.

By following these steps, you can create an S3 bucket in AWS quickly and securely, ready to store and manage your data in the cloud.
