2.1. Creating an S3 Bucket

1. Log In to AWS Management Console: Navigate to the AWS Management Console and log in.
2. Open S3 Service: Go to the S3 service from the AWS Management Console.
3. Create a Bucket: Click on “Create bucket,” enter a unique bucket name, and select the desired region.
4. Configure Bucket Settings: Configure settings such as versioning, logging, and permissions. Enable public access if you want your website to be publicly accessible.
5. Upload Website Files: Upload your website’s files (HTML, CSS, JS, images) to the bucket.

2.2. Configuring Bucket for Website Hosting

1. Enable Static Website Hosting: Select your bucket, go to the “Properties” tab, and enable static website hosting.
2. Specify Index Document: Enter the name of your main index file (e.g., index.html).
3. Specify Error Document: Optionally, enter the name of your error page (e.g., 404.html).
4. Save Changes: Apply and save the settings.

2.3. Configuring Bucket Policy

1. Set Bucket Policy: Go to the “Permissions” tab, and add a bucket policy to allow public access
2. Apply the Policy: Save and apply the policy to your bucket.

2.4. Accessing Your Website

1. Get the Website URL: From the S3 bucket properties, find the endpoint URL.
2. Visit Your Website: Use the endpoint URL to access your website.

3. Hosting a Dynamic Website on AWS EC2

For dynamic websites that require server-side processing and databases, Amazon EC2 is an appropriate choice.

3.1. Launching an EC2 Instance

1. Log In to AWS Management Console: Access your AWS Management Console.
2. Open EC2 Service: Navigate to the EC2 service.
3. Launch Instance: Click “Launch Instance” and select an Amazon Machine Image (AMI) based on your needs (e.g., Ubuntu, Amazon Linux).
4. Choose Instance Type: Select an instance type based on your performance requirements (e.g., t2.micro for basic usage).
5. Configure Instance Details: Set configurations such as network settings and IAM roles.
6. Add Storage: Configure storage options as needed.
7. Configure Security Group: Define firewall rules to allow HTTP/HTTPS traffic.
8. Review and Launch: Review settings and launch the instance. Create or select a key pair for SSH access.

3.2. Setting Up Your Web Server

1. Connect to Your Instance: Use SSH to connect to your EC2 instance.
2. Install Web Server Software: Install software like Apache, Nginx, or others.
3. Deploy Website Files: Upload your website files to the web server directory (e.g., /var/www/html for Apache).

3.3. Configuring Domain Name and DNS

1. Purchase a Domain: Use Amazon Route 53 or another domain registrar to purchase a domain name.
2. Configure DNS Settings: Set up DNS records to point to your EC2 instance’s public IP address or Elastic IP (if using a static IP).

3.4. Securing Your Website

1. Set Up HTTPS: Use AWS Certificate Manager (ACM) to obtain and configure SSL/TLS certificates.
2. Update Security Groups: Ensure your EC2 security group rules allow secure traffic (HTTPS).

4. Using AWS CloudFront for Improved Performance

AWS CloudFront can enhance your website’s performance by delivering content through a global network of edge locations.

4.1. Setting Up CloudFront

1. Open CloudFront Service: Go to the AWS Management Console and open CloudFront.
2. Create a Distribution: Click “Create Distribution” and select the origin type (e.g., S3 bucket or EC2 instance).
3. Configure Distribution Settings: Set up caching, security, and distribution settings as needed.
4. Deploy Distribution: Create and deploy your CloudFront distribution. It may take some time to propagate.

4.2. Updating Your Website to Use CloudFront
