[Overview] System Overview

Implemented secure global content distribution for Team Sports Enterprises using Amazon CloudFront and S3.

Achieved 60% faster content delivery with end-to-end encryption and Origin Access Control for secure S3 access.

[Context] Situation before

##### Key Challenges

Slow content delivery to global users.

Security concerns with direct S3 access.

High traffic peaks during tournament events.

Need for secure access to sensitive player documents.

[Diagnosis] The real problem

Provide fast, global content delivery.

Secure access to sensitive documents and media.

Enable reliable, automated deployment workflows.

Protect against DDoS and application-layer attacks.

Understanding the root cause changed everything.

[Boundaries] Working constraints

Amazon CloudFront

Amazon S3

Origin Access Control (OAC)

Amazon Route 53

AWS WAF

AWS Certificate Manager

Constraints are features, not obstacles. They guide design decisions.

[Decisions] Key tradeoffs

Ampity Infotech implemented a serverless content delivery architecture using CloudFront with Origin Access Control (OAC) for secure S3 access.

WAF integration provides protection against common web exploits. Route 53 enables reliable DNS routing with health checks.

[Design] Architecture design

CloudFront distribution with S3 origin and Origin Access Control. WAF web ACL attached to distribution for threat protection. HTTPS enforced through ACM certificate with automatic renewal.

[Approach] Execution model

##### Phase 1: S3 Configuration

Created S3 buckets with block public access and proper bucket policies for OAC.

##### Phase 2: CloudFront Setup

Configured CloudFront distribution with OAC, caching behaviors, and custom error pages.

##### Phase 3: Security Integration

Deployed WAF web ACL with managed rule groups and custom rate limiting.

##### Phase 4: DNS & SSL

Configured Route 53 routing and provisioned ACM certificate for HTTPS.

##### Phase 5: CI/CD Integration

Automated content deployment with cache invalidation on updates.

##### Phase 6: Monitoring

Set up CloudWatch dashboards and alarms for performance and security monitoring.

[Results] Measurable outcomes

##### 60% Faster Content Delivery

CloudFront edge locations dramatically reduced latency for global users.

##### End-to-End Encryption

HTTPS enforced throughout with ACM-managed certificates.

##### 70% Reduction in Release Time

Automated deployments with cache invalidation streamlined content updates.

##### Zero Downtime

Highly available architecture with global edge distribution.

[Anti-patterns] What could have gone wrong

##### Benefits

Global edge caching reduces origin load and latency.

Origin Access Control prevents direct S3 access.

WAF protection against DDoS and web exploits.

Automated certificate management with ACM.

[Applicability] Where this pattern applies

##### Good Fit

Global static content delivery.

Secure document distribution.

Applications requiring DDoS protection.

HTTPS-required deployments.

Every system is different. Context always matters.
