Enhancing Your web application’s Performance with AWS CloudFront

Exploring the integration of AWS CloudFront can significantly boost your web application’s performance. Let’s dive into how setting up CloudFront can enhance content delivery and streamline user experience.

Why Use CloudFront?

AWS CloudFront serves as a robust content delivery network (CDN) that speeds up the distribution of your static and dynamic web content, such as .html, .css, .js, and image files. Here’s how CloudFront can enhance your setup:

Improved Latency and Speed

CloudFront delivers content from the nearest edge location to the user, significantly reducing latency and improving the speed of content delivery. This is crucial for maintaining a fast and responsive user experience.

Scalability and Availability

If your application is mainly static (like my Jekyll blog is), using CloudFront, you can handle sudden spikes in traffic without any configuration changes. It automatically scales and accommodates changing traffic patterns, ensuring that your web application remains available and performs well under any load.

Enhanced Security

CloudFront integrates with AWS Shield, AWS Web Application Firewall (WAF), and Amazon Route 53 to provide a layered security approach. This helps protect your web application from common web exploits and DDoS attacks.

Hands-On: Setting Up CloudFront with ECS Fargate

I’ve recently added cloudfront as a tool to enhanced latency, speed, scalability and availability of my blog. Here’s a step-by-step guide that helps how I did it:

  1. Create a CloudFront Distribution: Setup is straightforward:
    • Origin Settings: I configure my ECS service’s load balancer as the origin. This is where CloudFront will fetch the needed content in the event of a cache miss.
  2. Cache Policy Configuration: I decided on the duration CloudFront caches my content. For me a year is great since I don’t think an article will change much once it’s released. And if I need to, I can trigger cache invalidations. You might opt for shorter durations if your web application content updates frequently.

  3. DNS Configuration: I adjusted my web application’s DNS settings to point to the CloudFront domain instead of directly to the load balancer. This change ensures that all traffic benefits from CloudFront’s optimizations.

  4. Adjust Security Group Settings: I made sure that my load balancer’s security group permits traffic from CloudFront. Typically, this involves allowing access on ports 80 and 443.


In my case, integrating CloudFront with ECS Fargate enhanced my web application’s performance by improving load times, scalability, and security. This setup not only ensures a better user experience but also leverages AWS’s robust infrastructure to handle traffic efficiently and securely.

Happy deploying!
