Amazon CloudFront delivery
Content served from an edge location near the user instead of a single origin — which is most of the fix for a site that feels slow far from where it is hosted.
CDN
Chosen per project
Maintainable handover
A large share of perceived slowness is distance. A site hosted in one region is genuinely further away for users elsewhere, and no amount of server tuning changes the speed of light.
A CDN caches your static assets — and often whole pages — at edge locations, so most requests never reach the origin at all. That makes the site faster and, as a side effect, considerably harder to overwhelm.
What we build with CloudFront
Sites with visitors spread across regions or countries
Media-heavy pages where images dominate load time
Protecting an origin server from traffic spikes
Serving a private S3 bucket publicly without making it public
Where it fits — and where it does not
Good fit when
Static assets — images, CSS, JavaScript, downloads
Content that changes on a schedule rather than per request
Any site where Core Web Vitals matter for search
Consider something else when
Highly personalised pages, which cache poorly without careful keying
Very small local-only sites, where the setup outweighs the gain
Where a cached request stops
The best request is the one that never reaches your server.
Browser cache
No network request at all.
Edge location
Served from a point of presence near the user.
Regional cache
A second tier before the origin is troubled.
Origin
Only for a miss, or content that must not be cached.
How we work with CloudFront
Cache policy per path
Long-lived caching for fingerprinted assets, short or no caching for HTML that changes.
Locked-down origin
Origin Access Control so the bucket or server only answers CloudFront, never the open internet.
Compression and modern formats
Brotli or gzip at the edge, and images served in modern formats where the browser supports them.
Invalidation discipline
Fingerprinted filenames so deployments do not depend on cache invalidation to be correct.
Our typical CloudFront setup
| Concern | What we use |
|---|---|
| Origins | S3 with Origin Access Control, or an application load balancer |
| TLS | Certificate from ACM, HTTP/2 and HTTP/3 enabled |
| Caching | Per-path policies; fingerprinted assets cached for a year |
| Security | Optional WAF, and origin locked to CloudFront only |
| Monitoring | Cache hit ratio and error rates tracked after launch |
Frequently asked questions
It fixes the distance component and the asset-delivery component, which together are often most of it. If the page is slow because a database query takes four seconds, the CDN will not help and we would look there instead.
Yes. The origin does not have to be on AWS — any reachable server can sit behind it.
By fingerprinting asset filenames so new files have new URLs, and keeping HTML on a short cache. That avoids relying on invalidations, which are slower and easy to forget.
