Amazon CloudFront
FreemiumAWS's global CDN, built to disappear into the rest of your AWS stack.
Published 27 September 2026
Scores
Popularity5/5
Backed by the dominant public cloud vendor and holding roughly a quarter of measured CDN market share, CloudFront is a name recognized across the industry, not just within CDN-specialist circles, and is the default answer for 'what CDN' in most AWS tutorials and reference architectures.
Learning Curve4/5
CloudFront distributions, cache and origin-request policies, IAM permissions, and ACM certificates are all AWS-specific concepts to learn before configuration feels natural; review sources consistently note the best experience belongs to teams already comfortable with AWS rather than newcomers bolting on a CDN.
Flexibility4/5
CloudFront Functions and Lambda@Edge cover both lightweight and heavyweight edge logic, and it can front S3, ALB, API Gateway, or any custom HTTP origin, though caching behavior is configured through AWS's policy objects rather than a fully open scripting layer like VCL.
Performance5/5
600+ edge locations across 100+ cities, backed by AWS's global network backbone, are consistently cited for low latency at scale across review sources.
Portability2/5
CloudFront can technically front any HTTP origin, but its deepest integrations — Lambda@Edge, CloudFront Functions, Origin Access Control, WAF, Shield, ACM certificates — are AWS-native and don't transfer to another cloud, so teams that lean into those capabilities couple their edge logic tightly to AWS.
About Amazon CloudFront
Amazon CloudFront is AWS's content delivery network, operating across 600+ edge locations in 100+ cities worldwide. It can front any HTTP origin, but its real strength is native integration with the rest of AWS: S3 buckets via Origin Access Control (signing requests so the bucket never needs to be public), Application Load Balancer, API Gateway, Route 53, and AWS Certificate Manager for TLS.
Edge compute comes in two tiers: CloudFront Functions for sub-millisecond JavaScript logic on headers and cache keys at massive scale, and Lambda@Edge for heavier transforms, authentication, or server-side rendering that needs a fuller Node.js/Python runtime. AWS WAF and Shield plug in directly for request filtering and DDoS protection without a separate vendor.
Pricing underwent a significant restructure, adding flat-rate named plans (Free, Pro, Business, Premium) alongside the classic pay-as-you-go model of data transfer plus request volume. The flat plans bundle WAF, DDoS protection, DNS, and S3 storage with no overage surprises, while the classic usage-based tiers still apply for teams that outgrow them or prefer granular billing. Every AWS account also keeps a permanent free tier — 1TB of data transfer and 10 million requests per month, with no 12-month expiration.
The tradeoff is depth of AWS knowledge required: distributions, cache/origin-request policies, IAM permissions, and ACM certificates are all AWS-specific concepts, so the smoothest experience belongs to teams already operating inside the AWS ecosystem rather than those bolting a CDN onto an unrelated stack.
Key Features
- 600+ edge locations across 100+ cities
- Origin Access Control for secure, non-public S3 origins
- CloudFront Functions — sub-millisecond edge JavaScript at massive scale
- Lambda@Edge for heavier compute (SSR, auth, transforms)
- Native AWS WAF and Shield integration for security
- Permanent free tier — 1TB transfer and 10M requests/month
- Flat-rate named plans (Free/Pro/Business/Premium) alongside classic usage-based billing
Pros
- Deep, native integration with S3, Lambda, ALB, Route 53, and ACM removes glue work for AWS-hosted stacks
- Extensive edge network delivers consistently low latency globally
- Origin Access Control gives a secure default for private S3-backed sites
- Permanent, uncapped-duration free tier is generous for small projects
- CloudFront Functions handle high-scale edge logic with very low overhead
Cons
- Steeper learning curve than single-purpose CDNs — requires comfort with IAM, ACM, and other AWS concepts
- Best experience is reserved for teams already running core infrastructure on AWS
- Pricing structure (data transfer + requests + optional features, plus newer flat plans) is more to reason about than a flat per-GB competitor
- Configuration (distributions, cache policies, origin-request policies) has more moving parts than most CDNs
Amazon CloudFront Pricing
Freemium- · Permanent free tier: 1TB data transfer out and 10 million HTTP/HTTPS requests per month, no expiration
- · 2 million CloudFront Function invocations per month included
- · Flat-rate plan bundling WAF, DDoS protection, DNS, and S3 storage with no overage charges
- · Suited to small production sites beyond the free tier
- · Higher included data transfer and request volume on the same flat-rate, bundled-feature model
- · Highest flat-rate tier for larger production workloads
- · Usage-based billing on data transfer out (from $0.085/GB in North America and Europe) plus per-request charges
- · Regional pricing varies — Asia ~$0.12/GB, India ~$0.109/GB, South America ~$0.11/GB
- · Still available for teams that prefer granular metered billing over the flat-rate plans

Alternatives to Amazon CloudFront(3)
The two most broadly recognized CDNs, but from different starting points — CloudFront wins for teams already built on AWS (S3, Lambda, ALB integration), while Cloudflare wins on its free tier and bundled security stack (WAF, DDoS, Zero Trust) independent of any single cloud vendor.
CloudFront is the natural choice for teams already deep in AWS infrastructure; Fastly is the alternative for teams that want CDN-vendor independence from AWS or need Fastly-specific capabilities like instant purge and VCL scripting.
CloudFront suits teams already on AWS that want deep integration with S3, Lambda, and IAM; Bunny.net is the alternative for teams outside the AWS ecosystem who want simpler, flat-rate pricing for static assets and video without AWS-specific configuration overhead.
