What exactly is a CDN?

A globally distributed network of servers that cache copies of your content close to users. It shortens the distance data travels, speeding up loads and offloading work from the origin server.

Does CloudFront improve SEO?

Indirectly yes: by reducing latency and improving Core Web Vitals (load speed), it helps ranking and user experience, factors Google takes into account.

Is CloudFront only for websites?

No: it speeds up and protects sites, applications, APIs and video streaming. Any content delivered over HTTP/HTTPS can benefit.

Amazon CloudFront — AWS CDN

AWS's content delivery network (CDN): it brings your website, APIs and video closer to users from hundreds of points of presence for a fast, secure experience.

What is Amazon CloudFront?

Amazon CloudFront is AWS's CDN (Content Delivery Network): a global network of edge servers that cache copies of your content close to users. When someone in Lima opens your site, the content is served from a nearby point of presence instead of traveling all the way to the origin server, reducing latency and improving conversion.

Beyond speed, CloudFront adds a security layer: it includes DDoS protection, pairs with AWS WAF to filter malicious traffic and handles HTTPS certificates. It also offloads work from the origin, lowering cost and increasing resilience against traffic spikes. Together with Amazon S3, it is the foundation of the fastest, hardest-to-take-down static websites.
