Global CDN Strategy & Implementation
Users expect fast experiences regardless of location, but serving global audiences from centralized infrastructure creates latency, scalability, and reliability challenges. Content delivery networks (CDNs) solve these problems by distributing content to edge locations worldwide. Drawing on experience implementing CDN strategies for enterprise applications serving millions of global users, including at Veeva supporting pharmaceutical companies across continents, we design and implement CDN solutions that deliver consistent performance, improve reliability, and reduce infrastructure costs.
Global Performance
Serve users worldwide with consistent low latency by distributing content across global edge networks, reducing load times by 50-70% for international audiences.
Scalability & Reliability
Handle traffic spikes and regional outages gracefully through distributed architecture, automatic failover, and elastic capacity that grows with demand.
Cost Optimization
Reduce origin server load and bandwidth costs through intelligent caching, edge computing, and efficient content distribution strategies.
Security Benefits
DDoS protection, WAF capabilities, SSL/TLS termination at the edge, and bot mitigation integrated into CDN services protect applications and data.
Enhanced Capabilities
Edge computing, image optimization, video streaming, and API acceleration unlock new features while improving performance.
Simplified Operations
Managed CDN services handle infrastructure complexity, allowing teams to focus on application development instead of global distribution.
Why CDN strategy matters
Geographic distance creates fundamental performance constraints. Network latency follows physics, and requests traveling from Tokyo to servers in Virginia experience unavoidable delay. For users far from origin servers, this manifests as slow page loads, sluggish interactions, and poor experiences compared to users nearby.
CDNs solve latency through geography: distributing content to edge servers near users worldwide. When configured properly, CDNs dramatically improve global performance while reducing origin server load, enabling graceful scaling during traffic spikes, and providing built-in DDoS protection and security features.
But CDN implementation requires strategic decisions: which content to cache, cache duration policies, invalidation strategies, handling of dynamic content, edge computing opportunities, and balancing cost versus performance. At Veeva, I worked on CDN strategies supporting global platforms where users in Europe, Asia, and the Americas expected equally fast experiences despite geographic distribution. This taught valuable lessons about cache behavior, origin shielding, edge computing, and measuring real-world CDN performance.
Our CDN implementation approach
Performance analysis
Analyze current global performance using real user monitoring data, identify geographic bottlenecks, assess content delivery patterns, and establish baseline metrics for improvement measurement.
CDN selection
Evaluate CDN providers (Cloudflare, Fastly, AWS CloudFront, Akamai) based on performance characteristics, geographic coverage, feature requirements, cost structure, and integration complexity appropriate for your needs.
Configuration & optimization
Implement intelligent caching strategies, cache invalidation workflows, edge rules, origin shielding, SSL/TLS configuration, and performance optimizations maximizing CDN effectiveness for your content types and traffic patterns.
Monitoring & refinement
Establish CDN performance monitoring, cache hit rate tracking, cost analysis, and ongoing optimization based on real usage patterns ensuring sustained performance improvements and cost efficiency.
CDN optimization strategies
Intelligent caching
Configure cache rules balancing freshness and performance: aggressive caching for static assets, short TTLs for frequently updated content, stale-while-revalidate patterns, and cache key customization optimizing hit rates while maintaining content accuracy.
Edge computing
Use edge functions (Cloudflare Workers, CloudFront Functions, Fastly Compute) for dynamic content generation, A/B testing, personalization, authentication, and API responses reducing latency for dynamic experiences.
Image optimization
Automated image transformation, format conversion (WebP, AVIF), responsive image generation, lazy loading, and intelligent compression at the edge reducing payload size while improving visual quality.
Origin protection
Origin shielding reduces load on application servers, DDoS protection mitigates attacks, rate limiting prevents abuse, and bot management filters malicious traffic before it reaches infrastructure.
CDN provider expertise
Cloudflare
Workers, Pages, Stream, Images, DDoS protection, WAF, and global anycast network for performance and security.

Common CDN use cases
Static site acceleration
Deploy static sites (Next.js, Gatsby, Hugo) to CDN edge locations for instant global delivery with zero server management and automatic HTTPS.
API acceleration
Cache API responses at the edge, implement API-specific cache strategies, and use edge computing for API aggregation or transformation reducing backend load and latency.
Media delivery
Optimize video streaming, image delivery, and large file distribution through CDN edge caching, adaptive bitrate streaming, and bandwidth optimization.
E-commerce optimization
Accelerate product pages, handle traffic spikes during sales events, optimize checkout flows, and personalize experiences while maintaining performance under load.
