Cloud Certification Exams and Introduction to storage in cloud computing

Now, let’s understand the steps involved in setting up an S3 bucket in a basic AWS cloud architecture.
Setting up an S3 storage bucket in AWS involves a few simple steps. Here’s a step-by-step guide to creating an S3 bucket:

1. Sign in to the AWS console: Log in to your AWS account using your credentials at https://aws.amazon.com/console/.
2. Open the S3 service: Once logged in, go to the AWS Management Console and search for S3 in the services search bar or navigate to the Storage section and click on S3.
3. Create a bucket: Click on the Create bucket button to start the process of creating a new S3 bucket.
4. Configure bucket settings: You’ll need to configure various settings for your bucket, including the following:
   A. Bucket name: Provide a globally unique name for your bucket. Bucket names must be unique across all existing bucket names in AWS.
   B. Region: Choose the AWS region where you want your bucket to be created. Consider choosing the region closest to your users to reduce latency.
   C. Block all public access: Choose whether you want to block all public access to your bucket or allow public access (read or write) to some extent.
5. Set up bucket permissions: You can set up bucket permissions to control access to your S3 bucket. This includes bucket policies and ACLs. By default, the bucket owner has full control over the bucket.
6. Configure advanced settings: You can configure additional options such as logging, tags, events, and versioning based on your requirements. These settings help you manage and track activities within your bucket effectively.
7. Review and create: After configuring all the necessary settings, review your choices and click on the Create bucket button to create the S3 bucket.
8. Bucket created: Once the bucket has been created successfully, you will see it listed in your S3 dashboard.
   That’s it! You’ve now set up an S3 bucket in AWS. From here, you can start uploading objects (files) to your bucket and manage them as needed. Remember to follow AWS best practices for securing and managing your S3 bucket to ensure the safety of your data.
   Now, to create an S3 bucket using the AWS Command-Line Interface (CLI) in the AWS CloudShell utility, follow these steps:
9. Access AWS CloudShell: Go to the AWS Management Console and click on the Services menu. In the Security, Identity, & Compliance section, click on CloudShell.
10. AWS CLI installation: AWS CloudShell comes pre-installed with the AWS CLI. If you are using the CLI on your local machine, make sure you have it installed and configured with your AWS credentials. In CloudShell, this step is not required as it’s already set up.
11. Create an S3 bucket: To create an S3 bucket, open the AWS CloudShell terminal and execute the following command:

aws s3api create-bucket –bucket YOUR_BUCKET_NAME –region YOUR_REGION

4. Replace YOUR_BUCKET_NAME with the desired name for your bucket and YOUR_REGION with the AWS region where you want to create the bucket (for example, us-east-1).
5. Set up bucket permissions (optional): By default, the bucket owner has full control over the newly created bucket. If you want to grant public read access to the bucket, you can add the following command:

aws s3api put-bucket-acl –bucket YOUR_BUCKET_NAME –acl public-read

This will set the bucket ACL to allow public read access to objects in the bucket.

6. Configure advanced settings (optional): You can configure additional settings for your bucket using various CLI commands, such as enabling versioning, logging, and adding tags. Here are some examples:
   • Enable versioning:

aws s3api put-bucket-versioning –bucket YOUR_BUCKET_NAME –versioning-configuration Status=Enabled

• Enable server access logging:
aws s3api put-bucket-logging –bucket YOUR_BUCKET_NAME –bucket-logging-status file://logging-config.json

• Add tags to the bucket:
aws s3api put-bucket-tagging –bucket YOUR_BUCKET_NAME –tagging file://tagging-config.json

NOTE
For the preceding commands, you need to provide the corresponding JSON files (logging-config.json and tagging-config.json) with the appropriate configurations.
Remember to replace YOUR_BUCKET_NAME and YOUR_REGION with your desired values in each command.
Once the commands are executed successfully, your S3 bucket will be created with the specified settings. You can check your S3 dashboard in the AWS Management Console to verify the bucket creation and configurations.
