This curriculum spans the technical and operational breadth of enterprise CDN management, comparable in scope to a multi-workshop program developed for organisations designing, securing, and operating global content delivery at scale.

Module 1: CDN Architecture Fundamentals and Topology Selection

  • Decide between flat vs. hierarchical CDN architectures based on regional traffic patterns and origin server proximity.
  • Configure Points of Presence (PoPs) placement considering latency, peering agreements, and ISP interconnectivity in target markets.
  • Evaluate multi-homed vs. single-homed edge server designs to balance redundancy and operational complexity.
  • Select transport protocols (e.g., TCP optimizations, QUIC) at the edge based on client device support and packet loss profiles.
  • Implement DNS-based load balancing with geo-proximity routing to direct users to the optimal PoP.
  • Assess the trade-offs of deploying private CDN nodes versus leveraging third-party infrastructure for compliance-sensitive content.

Module 2: Caching Strategy and Content Invalidation

  • Define cache key composition by including or excluding query string parameters, cookies, and headers based on content variability.
  • Implement time-based TTLs versus event-driven invalidation based on content update frequency and origin load tolerance.
  • Configure cache hierarchies with parent-child relationships to reduce origin fetches during cache misses.
  • Design stale-while-revalidate policies to serve outdated content during origin fetches without degrading user experience.
  • Integrate cache purge workflows with CI/CD pipelines to automate content invalidation after deployment.
  • Monitor cache hit ratio per content type and adjust TTLs dynamically to optimize origin offload and freshness.

Module 3: Security Integration and Threat Mitigation

  • Deploy WAF rules at the edge to block OWASP Top 10 vulnerabilities without increasing origin server load.
  • Configure bot management policies to distinguish between malicious scrapers and legitimate search engine crawlers.
  • Implement TLS 1.3 with modern cipher suites and enforce HSTS across all edge domains.
  • Manage certificate lifecycle at scale using automated provisioning and renewal across distributed PoPs.
  • Integrate DDoS mitigation with real-time traffic scrubbing and adaptive rate limiting at the edge.
  • Enforce signed URLs or tokens for access to private content, balancing security with client-side implementation complexity.

Module 4: Performance Optimization and Latency Reduction

  • Enable HTTP/2 or HTTP/3 at the edge to reduce connection overhead for multiplexed asset delivery.
  • Implement image optimization pipelines with dynamic resizing, format conversion (e.g., WebP), and quality reduction.
  • Configure Brotli or Gzip compression levels based on CPU cost at the edge versus bandwidth savings.
  • Deploy edge-side includes (ESI) to assemble personalized content at the edge while caching static fragments.
  • Implement prefetching and preloading strategies using Link headers based on navigation patterns.
  • Optimize Time to First Byte (TTFB) by tuning keep-alive settings and connection pooling between edge and origin.

Module 5: Origin Shield and Traffic Management

  • Deploy origin shields to absorb cache misses and prevent thundering herd scenarios during content warm-up.
  • Configure health checks and failover logic between primary and backup origins with appropriate probe intervals.
  • Implement adaptive retry policies with exponential backoff for failed origin requests.
  • Set up origin request throttling to protect backend systems during traffic spikes or misconfigured clients.
  • Use request collapsing to coalesce identical origin fetches from multiple edge nodes.
  • Monitor origin response times and error rates to trigger automated configuration adjustments or alerts.

Module 6: Observability, Monitoring, and Log Management

  • Aggregate edge logs across PoPs with consistent schema for centralized analysis and compliance reporting.
  • Define SLI/SLOs for cache hit ratio, latency, and error rates with automated alerting on breach.
  • Instrument real user monitoring (RUM) to correlate edge performance with end-user experience metrics.
  • Configure sampling rates for access logs to balance cost and diagnostic fidelity during high traffic.
  • Use synthetic transactions to validate edge behavior and detect configuration drift across regions.
  • Integrate CDN metrics with existing observability platforms (e.g., Prometheus, Datadog) using standard APIs.

Module 7: Multi-CDN Orchestration and Vendor Management

  • Implement DNS-based or anycast routing to distribute traffic across multiple CDN providers based on performance data.
  • Develop health scoring algorithms that evaluate CDN performance using latency, availability, and error rates.
  • Negotiate SLAs with CDN vendors that include measurable penalties for sustained SLO violations.
  • Standardize configuration templates across vendors to reduce operational overhead and misconfiguration risk.
  • Conduct regular failover drills to validate traffic redirection during provider outages.
  • Centralize billing and usage reporting across providers to identify cost anomalies and optimize spend.

Module 8: Compliance, Data Residency, and Legal Considerations

  • Enforce data residency policies by restricting edge caching of personal data to jurisdiction-specific PoPs.
  • Implement audit logging for access to sensitive content with retention periods aligned to regulatory requirements.
  • Configure cookie handling at the edge to comply with GDPR and CCPA consent mechanisms.
  • Disable logging of personally identifiable information (PII) in edge access logs using field masking.
  • Validate CDN provider certifications (e.g., SOC 2, ISO 27001) for alignment with enterprise security policies.
  • Establish data processing agreements (DPAs) with CDN vendors to clarify responsibilities under privacy laws.
