This curriculum spans the technical, operational, and compliance dimensions of CDN management in large-scale content delivery environments, comparable in scope to a multi-workshop operational immersion for cloud infrastructure teams designing and running global media or SaaS platforms.

Module 1: CDN Infrastructure Sourcing and Provider Selection

  • Evaluate multi-vendor RFP responses based on peering agreements, backbone reach, and regional PoP density in emerging markets.
  • Assess ownership models: weigh capital expenditure for private CDN deployment against SLA limitations of public providers.
  • Compare BGP routing policies across CDN vendors to determine failover responsiveness during regional outages.
  • Negotiate custom interconnection agreements with ISPs to reduce transit costs for high-volume media delivery.
  • Validate DDoS mitigation capacity by reviewing historical attack logs and scrubbing center locations.
  • Conduct side-by-side latency testing using traceroute and DNS resolution benchmarks across third-party monitoring tools.

Module 2: Edge Caching Architecture and Content Invalidation

  • Design TTL policies for dynamic versus static assets based on update frequency and origin load tolerance.
  • Implement cache key normalization to prevent cache duplication from query string variations.
  • Deploy selective cache purging using tag-based invalidation instead of full-path purges to reduce origin burst load.
  • Integrate stale-while-revalidate and stale-if-error directives to maintain availability during origin degradation.
  • Configure cache hierarchies with regional edge and global origin shield layers to minimize upstream fetches.
  • Monitor cache hit ratio by content type and geography to identify misconfigured resources or routing anomalies.

Module 3: Security Integration and Threat Mitigation

  • Enforce TLS 1.3-only connections at the edge and manage certificate lifecycle using automated provisioning tools.
  • Implement WAF rule tuning to balance false positives in API traffic against OWASP Top 10 coverage.
  • Configure bot management policies to differentiate between scrapers, credential stuffers, and legitimate crawlers.
  • Deploy geo-fencing at the DNS or HTTP level to restrict access to region-licensed content.
  • Integrate CDN logs with SIEM systems using structured JSON formats for real-time threat correlation.
  • Validate DDoS protection efficacy by conducting controlled synthetic flood tests during off-peak hours.

Module 4: Performance Optimization and Latency Management

  • Optimize image delivery using client hints and adaptive compression (WebP/AVIF) based on device capabilities.
  • Implement HTTP/2 server push selectively to avoid bandwidth contention on high-latency links.
  • Use real-user monitoring (RUM) data to adjust origin fetch timeouts and retry backoff strategies.
  • Deploy TCP optimization techniques such as BBR congestion control on origin servers to improve fetch throughput.
  • Configure DNS TTL and EDNS Client Subnet to improve GSLB accuracy and reduce cross-region routing.
  • Instrument first-byte and time-to-content metrics per PoP to detect underperforming edge locations.

Module 5: Traffic Management and Load Distribution

  • Design health check probes with synthetic transactions that validate both HTTP status and content integrity.
  • Implement weighted routing policies to shift traffic gradually during origin migrations or failovers.
  • Use Anycast DNS with latency-based steering to direct users to the closest operational edge cluster.
  • Configure circuit breakers at the edge to prevent cascading failures from origin saturation.
  • Balance cost and performance by routing non-critical traffic through lower-tier PoPs with higher latency.
  • Monitor DNS query patterns to detect resolver misbehavior or third-party DNS services causing suboptimal routing.

Module 6: Observability, Monitoring, and Incident Response

  • Aggregate CDN access logs across providers using a centralized data lake for cross-platform analysis.
  • Define SLOs for cache hit ratio, origin fetch latency, and error rates with corresponding error budgets.
  • Correlate edge server error codes (e.g., 5xx) with origin health metrics to isolate failure domains.
  • Automate alerting on sudden drops in regional traffic volume that may indicate DNS or BGP hijacking.
  • Conduct post-mortems on cache stampedes following mass invalidations or origin outages.
  • Validate log sampling rates to ensure forensic data accuracy without incurring excessive storage costs.

Module 7: Cost Governance and Financial Operations

  • Map egress bandwidth usage by customer, application, and content type to enforce chargeback models.
  • Negotiate tiered pricing based on committed monthly bandwidth and adjust traffic shaping accordingly.
  • Identify cost anomalies from unexpected surges in video streaming or API payloads using usage dashboards.
  • Optimize compression and minification workflows to reduce byte volume and associated egress fees.
  • Compare cost-per-GiB across CDN providers for different geographic regions and adjust routing policies.
  • Implement automated shutdown of test/staging CDN configurations to prevent idle resource billing.

Module 8: Regulatory Compliance and Data Residency

  • Configure edge rules to block or redirect requests from jurisdictions with data sovereignty laws (e.g., GDPR, CCPA).
  • Audit log retention practices to ensure compliance with regional data protection requirements.
  • Validate that user data (e.g., cookies, headers) is not cached or logged in non-compliant regions.
  • Implement consent management platform (CMP) integration at the edge for geo-specific tracking enforcement.
  • Document data flow diagrams showing content routing paths for regulatory audits.
  • Use CDN provider attestations (SOC 2, ISO 27001) as part of vendor risk assessment for third-party processing.
