Amplifying Website Performance with AWS: Beyond Core Web Vitals

Explore advanced AWS strategies for boosting website performance, covering tactics like sophisticated caching, file compression, and utilizing CloudFront and S3 to their fullest potential.

Boosting Website Performance on AWS: Strategies Beyond Core Web Vitals


Optimizing website performance on AWS involves a symphony of strategies, well beyond just focusing on Core Web Vitals. This article delves into how AWS services like CloudFront and S3 can be fine-tuned to significantly enhance your site’s speed and user experience.

Advanced Techniques for Performance Enhancement

  1. Sophisticated Browser Caching: Leverage browser caching to reduce server hits and speed up page loads for repeat visitors. On AWS S3, this can be achieved with a command like:

    aws s3 cp --cache-control max-age=3153600,public s3://yourbucket/yourfile s3://yourbucket/yourfile

    This command sets a long cache lifetime, ensuring that your static content is stored in users’ browsers.

  2. File Compression: Compress your files to slash loading times. AWS S3 supports this with a simple command line:

    aws s3 cp --content-encoding gzip s3://yourbucket/yourfile s3://yourbucket/yourfile

    Pre-compress files before upload to maximize efficiency.

  3. CloudFront Edge Node Caching: Utilizing AWS CloudFront, distribute your content across global edge locations. This reduces latency by serving content from the nearest edge location to your users.

  4. Optimizing S3 Storage Classes: Choose the right S3 storage class for your use case. For frequently accessed content, use S3 Standard. For less accessed content, consider S3 Intelligent-Tiering, which automatically moves data to the most cost-effective access tier.

  5. HTTP/2 Support: Enable HTTP/2 in CloudFront. It allows multiple requests and responses between the client and server in parallel, reducing the load time.

  6. TLS Optimization: Use TLS 1.3 on CloudFront. It’s faster and more secure, reducing the time for SSL/TLS handshakes.

  7. Image Optimization: Use image formats like WebP for better compression and quality. AWS Lambda@Edge can dynamically convert images to WebP based on browser support.

  8. Lambda@Edge for Custom Code: Execute custom code closer to users with Lambda@Edge. This is useful for SEO redirects, A/B testing, or user authentication.


By implementing these tactics, you’re not just boosting performance metrics but also enhancing the overall user experience on your website. It’s all about delivering content swiftly and efficiently.

Fun Fact:

The term “browser war” refers to the competition between web browsers. The first one started in the late 1990s, primarily between Internet Explorer and Netscape!
