Using an S3 bucket for a website can significantly improve performance. This is because S3 buckets are designed to handle high traffic and can serve static content quickly.

Static content such as images and CSS files can be stored in an S3 bucket and served directly to users. This reduces the load on your server and improves page load times.

S3 buckets also provide a Content Delivery Network (CDN) that caches content across multiple servers. This means that users will get the content from a server closest to them, reducing latency.

By hosting your website's static content in an S3 bucket, you can free up resources on your server and focus on dynamic content and functionality.

Set Up

To set up an S3 bucket for your website, you'll need to create an Amazon S3 bucket and enable website hosting on it. You can automate this process using Terraform, an open-source infrastructure as code tool.

First, create the S3 bucket on AWS by typing a unique bucket name, selecting the region where to host the bucket, and enabling public access. You can also add tags and configure encryption settings as needed.

To create the bucket, follow these steps: type a bucket name, select the region, and enable public access. In the Object Ownership section, leave it as is. In the section "Block Public Access settings for this bucket", untick the checkbox Block all public access and tick the checkbox I acknowledge that the current settings might result in this bucket and the objects within becoming public.

Here are the specific settings to use when creating the S3 bucket:

Next, create the CloudFront distribution by typing the origin domain related to your S3 bucket, giving a name to the distribution, and restricting bucket access to CloudFront only. You'll also need to change the viewer protocol policy to "Redirect HTTP to HTTPS" and leave the rest of the settings as is.

To create the CloudFront distribution, follow these steps: type the origin domain, give a name to the distribution, and restrict bucket access to CloudFront only. In the section "Origin access", tick the radio button with the label "Origin access control settings (recommended)". In the section "Default cache behavior", change the value to "Redirect HTTP to HTTPS".

Uploading and Hosting

Uploading and hosting your website on an S3 bucket is a straightforward process. You can upload website files to your S3 bucket by navigating to the bucket, clicking the Upload button, and adding all the files for your website.

To ensure proper file hierarchy, add files and folders individually, rather than uploading the entire project at once. Your index page should be at the root of the S3 bucket.

Once your files are uploaded, enable static website hosting for the bucket by clicking on the Properties tab, scrolling down to the Static website hosting section, and clicking on the Edit button. Select the Enable option and provide your website's default home page and error page.

You can upload files to your S3 bucket using the Objects tab.

Navigate to the S3 bucket you intend to host your website.

Click on Upload, add all of the files for your website, and click on Upload at the bottom when finished.

Be sure to upload files one by one to avoid issues with file hierarchy.

Ensure that your index page is at the root of the S3 bucket.

This is important for your website to be accessible.

You can also use the AWS CLI to upload files to the S3 bucket.

This is helpful when using a script to deploy your website.

The recursive option allows copying subfolders.

The command to upload the "dist" folder to the S3 bucket is provided in the AWS CLI instructions.

Enabling Hosting

Enabling hosting is a crucial step in getting your website live. To do this, you need to enable static website hosting on your S3 bucket.

First, click on the Properties tab and scroll down to the Static website hosting section. Get access to the static website hosting settings by clicking on the Edit button under the Static website hosting section.

Select the Enable option to enable static website hosting. Provide your website's default home page (Index document) and error page (Error document). You can leave the Error document field blank as it is optional.

The index document is the default page users will see when they access your website. Save the changes you made in the Index and Error document field by clicking on the Save changes button.

Take note of the website endpoint that you can see by scrolling down to the Static website hosting section in the Properties area. The website endpoint is a URL you'll use to test your website.

To test your website, paste the website endpoint into your browser's address bar. If your setup is correct, you'll get to access your website publicly.

Security and Access

To secure your S3 bucket, you must assign an S3 bucket policy that allows all users to read objects inside the bucket. This policy should be set up while on your S3 bucket in the AWS Management Console, specifically on the Permissions tab.

You'll need to scroll down to the Bucket policy and copy and paste a specific policy that allows all users to read any objects inside the bucket. This policy is "*": "Action":["s3:GetObject"].

After pasting the policy, save the bucket policy by clicking on Save changes at the bottom of the page. This step is crucial to securing your S3 bucket.

To allow the CloudFront distribution to access the S3 bucket, you'll need to edit the bucket policy and replace the bucket name and CloudFront distribution ARN with the correct values. This will enable the CloudFront distribution to get files from the S3 bucket.

Once the policy is updated, click the "Save changes" button to finalize the changes. After saving, locate the text input with the label "Default root object" and type the value "index.html".

Static Site Hosting

To host a static website on Amazon S3, you need to enable static website hosting for the bucket. This can be done by clicking on the Properties tab, scrolling down to the Static website hosting section, and clicking on the Edit button.

To configure the static website hosting, you need to select the Enable option and provide your website's default home page (Index document) and error page (Error document). The index document is the default page users will see when they access your website, while the error document will appear if an error occurs.

You can leave the Error document field blank as it is optional. The index document can be any file name, but it's common to use "index.html". The website endpoint is a URL you'll use to test your website, and it can be found by scrolling down to the Static website hosting section in the Properties area.

To test your website, paste the website endpoint into your browser's address bar. If your setup is correct, you'll see your website publicly, but it will not be secure as indicated in the address bar (Not secure).

To serve a secure version of your website, you can use Amazon CloudFront, which is AWS' Content Delivery Network (CDN) service. CloudFront will distribute your website closer to your audience, improving performance and resiliency.

Here are the basic steps to create a CloudFront distribution:

  • Create a CloudFront distribution by clicking on the Create a CloudFront distribution button.
  • Set an origin domain by entering your S3 bucket endpoint in the Origin domain field.
  • Select the Redirect HTTP to HTTPS option under Viewer protocol policy to force all HTTP traffic to HTTPS.
  • Add your domain name in the Alternate domain (CNAME) section and select the certificate that was issued to your domain.
  • Click the Create distribution button to create the distribution.

Once you've created your CloudFront distribution, you can test it by copying the distribution's domain name and pasting it into your browser's address bar. If your setup is correct, you'll see your website's home page displayed by default, and it will be secure as indicated by the https prefix or padlock icon in your browser's address bar.

Cost and Performance
