Introduction
In today’s digital-first environment, Speed and reliability are critical for businesses delivering content to global users. Whether you run a SaaS platform, eCommerce store, or media streaming service, optimizing content delivery ensures low latency, high availability, and cost efficiency.
So, How do you achieve this? The answer is AWS CloudFront.
As the Head of Engineering at Bacancy, I’ve worked with companies across industries to fine-tune CloudFront to help them achieve seamless, high-performance content delivery. In this guide, I'll walk you through the key steps to optimize content delivery with AWS CloudFront, backed by real-world insights from our work at Bacancy.
What is AWS CloudFront?
AWS CloudFront is a powerful content delivery network (CDN) provided by Amazon Web Services. It is designed to securely deliver a wide range of content, such as videos, data, applications, and APIs, to users across the globe with minimal latency and high-speed data transfers. It works by caching content at edge locations worldwide, reducing the need to fetch data from the origin server every time a user makes a request.
Why Use AWS CloudFront?
- Faster Load Times – Content is served from the nearest AWS edge location.
- Reduced Server Load – Caching minimizes the number of direct requests to the origin.
- Enhanced Security – Integrated with AWS WAF, DDoS protection, and SSL/TLS encryption.
- Cost Optimization – Less data transfer from the origin, leading to lower AWS bills.
Now that we understand why it is a game-changer, let’s dive into the key steps to optimize content delivery with AWS CloudFront for maximum performance and efficiency.
5 Key Steps to Optimize Content Delivery with AWS CloudFront
Here is a curated list of the key steps to follow for enhanced content delivery with AWS CloudFront
1. Choose the Right CloudFront Distribution Settings
AWS CloudFront supports two types of distributions:
Web Distributions (for static & dynamic content)
RTMP Distributions (for media streaming – now deprecated)
✅ Best Practice: If you’re delivering web content (HTML, CSS, JavaScript, APIs, images, videos, etc.), always opt for a Web Distribution.
💡 Example: One of our clients, an eCommerce business, was using inefficient cache settings on CloudFront, causing delays in product image loading. We optimized their Web Distribution and cache policies, reducing their page load time by 40%—which directly boosted conversions.
2. Optimize Cache Behavior for Faster Load Times
Caching plays a major role in CloudFront performance. Configuring it correctly can significantly reduce latency and backend server load.
🔹 Enable Origin Shield – Reduces origin load by caching content closer to users.
🔹 Set Up Cache-Control Headers – Use max-age and s-maxage to define caching rules.
🔹 Leverage CloudFront Functions – Customize caching logic at the edge.
✅ Best Practice: Configure Time-to-Live (TTL) values appropriately:
Static files: Longer TTL (e.g., 1 week or more)
Dynamic content: Shorter TTL (e.g., 5–10 minutes)
3. Use AWS WAF for Enhanced Security
Security is non-negotiable when serving global traffic. AWS Web Application Firewall (WAF) adds an extra layer of protection.
🔹 Protect Against DDoS & Bots – Use AWS Shield and WAF rules to prevent attacks.
🔹 Restrict Access – Implement signed URLs and geo-blocking for sensitive content.
🔹 Monitor Traffic – Leverage AWS CloudWatch for security insights.
How we do it at Bacancy: For a SaaS client, we set up AWS WAF with rate limiting, preventing bot-driven API abuse—saving $30,000 annually on AWS costs.
4. Implement HTTP/3 for Faster Connectivity
HTTP/3 with QUIC is the latest protocol that improves speed and performance. It reduces handshake times and enhances streaming and real-time interactions.
🔹 Enable HTTP/3 in your CloudFront settings.
🔹 Ensure your backend servers support HTTP/3.
🔹 Test performance with AWS CloudFront Logs & Real-Time Metrics.
How we do it at Bacancy: When we enabled HTTP/3 for a media-streaming client, their buffering time dropped by 55%, improving user retention.
5. Reduce AWS Costs with Smart Optimization
AWS CloudFront follows a pay-as-you-go pricing model, where costs are primarily driven by data transfer out and HTTP/HTTPS requests. These costs can escalate quickly if not managed properly, especially for high-traffic applications.
To optimize costs while maintaining performance, here are some smart strategies:
- Compress Assets: Use Gzip & Brotli to minimize file size.
- Enable Lambda@Edge: Offload logic to edge locations, reducing origin traffic.
- Use Regional Edge Caches: Reduce requests to the origin server.
How we do it at Bacancy: By compressing assets and offloading logic to Lambda@Edge, we helped one of our clients cut their AWS bill by 35%.
6. Improve Performance with Multi-CDN Strategy
For businesses serving a global audience, using multiple CDNs (e.g., CloudFront + Akamai) can enhance resilience and performance.
🔹 AWS CloudFront + Multi-CDN Benefits:
- Faster failover in case of CDN outages
- Reduced latency for users in different geographies
- Improved cost efficiency by leveraging price differences
How we do it at Bacancy: One of our gaming clients deployed AWS CloudFront + Fastly for a hybrid approach, improving global latency by 50%.
7. Monitor & Continuously Optimize with AWS Tools
Ongoing monitoring is crucial to ensure consistent performance and cost efficiency.
📊 Key AWS Monitoring Tools:
- Amazon CloudWatch – Real-time logs & metrics.
- AWS X-Ray – Track request paths for debugging.
- AWS Cost Explorer – Monitor CloudFront cost trends.
How we do it at Bacancy: We conduct monthly performance audits for our clients to identify optimization opportunities and cost-saving strategies.
Conclusion: Optimize Content Delivery With AWS CloudFront
Optimizing AWS CloudFront isn’t just about speed—it’s about efficiency, security, and cost control. By following the steps to optimize content delivery with AWS CloudFront, such as–smart caching, security enhancements, HTTP/3, and continuous monitoring, you can deliver seamless experiences to users worldwide.
