Why choose Amazon CloudFront as your CDN





By implementing new features more frequently AWS is always standing out in the content delivery segment in comparison to other open source services. Below we will learn about the perks of having CloudFront as your content delivery service rather than any other outside service to give your website performance a boost.


Why CloudFront ?
Amazon CloudFront, a fully managed content delivery network (CDN) service, offers several advantages over open-source CDN solutions. Here are some perks of CloudFront in comparison to other open-source CDN services:


1. Global Edge Locations:

- CloudFront: Amazon CloudFront has a vast global network of edge locations, ensuring low-latency content delivery to end-users worldwide. These edge locations are strategically placed around the world, reducing latency and enhancing user experiences.

- Open Source CDN: While open-source CDNs can be deployed globally, achieving the same level of global reach and low-latency performance often requires significant effort in terms of infrastructure and maintenance.


2. Ease of Setup and Management:

- CloudFront: CloudFront is fully managed by AWS, which means you don't need to worry about provisioning and maintaining servers or software. Setting up CloudFront is user-friendly through the AWS Management Console, CLI, or SDKs.

- Open Source CDN: Implementing and managing open-source CDN solutions typically requires a more significant investment of time, expertise, and resources for setup, configuration, and ongoing maintenance.


3. Scalability:

- CloudFront: CloudFront can seamlessly handle traffic spikes and scale automatically, thanks to the vast AWS infrastructure. It provides dynamic scalability, making it suitable for applications with varying traffic patterns.

- Open Source CDN: Scaling open-source CDN solutions may require more manual intervention and may not scale as easily or cost-effectively as a cloud-based solution like CloudFront.


4. Integration with AWS Services:

- CloudFront: CloudFront integrates seamlessly with various AWS services, including Amazon S3, Lambda@Edge, and AWS Shield. This integration simplifies content delivery and enhances the overall AWS ecosystem.

- Open Source CDN: Open-source CDN solutions may lack the tight integration with a wide range of cloud services and may not provide the same level of compatibility with the broader cloud ecosystem.


5. Security and DDoS Protection:

- CloudFront: CloudFront is integrated with AWS Web Application Firewall (WAF) and AWS Shield, offering robust protection against DDoS attacks and other security threats. AWS's security expertise enhances the level of protection provided.

- Open Source CDN: While open-source CDN solutions can be secured, they may not have the same level of security features, expertise, and integrated security services offered by a cloud-based CDN like CloudFront.


6. Cost-Efficiency:

- CloudFront: AWS's pay-as-you-go pricing model allows you to pay only for the data transfer and requests you use. Additionally, AWS often offers a free tier for the first 12 months, making it cost-effective, especially for smaller businesses and startups.

- Open Source CDN: Open-source CDN solutions may have lower upfront costs, but they may require more significant investment in hardware, infrastructure, and ongoing maintenance, potentially resulting in higher total cost of ownership.

While open-source CDN solutions have their merits and are often chosen for specific use cases, Amazon CloudFront's global reach, ease of use, scalability, integration with AWS services, security features, and cost-efficiency make it an attractive choice for businesses looking for a fully managed CDN solution. The choice ultimately depends on your specific requirements and the resources available for managing the CDN.


What’s currently new at CloudFront ?

You can now sort query strings with CloudFront Functions

“You can use CloudFront Functions to improve cache hit rates on CloudFront by sorting query string parameters. CloudFront Functions enables you to personalize content with low latency while delivering web traffic on CloudFront. This new feature allows you to alphabetize or change the order or case of query strings to improve caching.”

You can now review and enable AWS WAF security recommendations

“CloudFront conveniently displays security rules for you based on elements of your CloudFront configuration including path patterns or your origin type. Additionally to help protect against HTTP floods, Amazon has added a guided workflow to rate limit requests when they are coming at too fast a rate.”

You can now secure your web applications and APIs with AWS WAF with a single click

“Previously, you could secure your CloudFront distributions with AWS WAF by preconfiguring an AWS WAF web access control list (web ACL) containing the security rules you wanted to enable. Now, CloudFront handles creating and configuring AWS WAF for you with out-of-the-box protections recommended by AWS for all applications.”
