This curriculum spans the technical and operational rigor of a multi-phase CDN infrastructure rollout, comparable to an internal engineering program for global edge network deployment across topology design, caching, security, and compliance.

Module 1: Network Topology Design and Edge Infrastructure Planning

  • Selecting between regional edge clusters and global tiered caching hierarchies based on latency SLAs and content type distribution patterns.
  • Deploying Points of Presence (PoPs) in carrier-neutral data centers versus cloud provider regions to balance cost, peering, and redundancy.
  • Implementing Anycast routing for edge nodes to optimize client proximity and failover behavior during outages.
  • Configuring BGP communities and AS path prepending to influence upstream ISP traffic routing decisions.
  • Assessing the trade-off between PoP density and operational complexity in emerging markets with limited IXPs.
  • Integrating real-time network telemetry from edge routers to automate topology adjustments during congestion events.

Module 2: Content Caching Strategies and Cache Hierarchy Management

  • Defining TTL policies for dynamic vs. static assets based on origin update frequency and cache hit ratio targets.
  • Implementing cache key normalization rules to prevent cache fragmentation from query string variations.
  • Designing multi-tier cache architectures (edge, mid-tier, origin shield) to absorb traffic spikes and reduce origin load.
  • Enabling stale-while-revalidate and stale-if-error directives to maintain availability during origin degradation.
  • Configuring cache bypass rules for authenticated or personalized content to prevent data leakage.
  • Monitoring cache hit ratio per content class and adjusting eviction algorithms (LRU, LFU) accordingly.

Module 4: Traffic Management and Request Routing Intelligence

  • Configuring DNS-based load balancing with health checks to route clients to the nearest healthy PoP.
  • Implementing HTTP redirect steering when DNS TTL prevents rapid failover at the edge.
  • Using client subnet information in EDNS0 to improve geolocation accuracy for routing decisions.
  • Integrating real-user monitoring (RUM) data into routing logic to adapt to actual performance, not just proximity.
  • Setting up traffic shedding rules during DDoS events to protect origin infrastructure without full blackholing.
  • Managing TTLs for DNS records to balance responsiveness and DNS query load across resolvers.

Module 5: Security Enforcement and Threat Mitigation at Scale

  • Deploying layered DDoS protection with on-path scrubbing at edge PoPs and off-path signaling via BGP Flowspec.
  • Configuring WAF rule sets with minimal false positives for API endpoints exposed through the CDN.
  • Implementing bot mitigation using behavioral fingerprinting and rate limiting per client ASN or /24 block.
  • Managing TLS certificate lifecycle across thousands of edge nodes with automated renewal and revocation checks.
  • Enforcing HTTP security headers (HSTS, CSP, X-Frame-Options) at the edge for origin applications lacking native support.
  • Isolating tenant traffic in multi-tenant CDNs using namespace segregation and encrypted SNI (ESNI) where supported.

Module 6: Performance Optimization and Protocol Engineering

  • Enabling HTTP/2 and HTTP/3 with connection coalescing to reduce round trips for multi-origin sites.
  • Tuning TCP congestion control algorithms (e.g., BBR vs. Cubic) per PoP based on observed RTT and loss rates.
  • Implementing image optimization pipelines with client hints (DPR, Width, Viewport-Width) for responsive delivery.
  • Using origin pre-fetch and proactive cache warming based on traffic forecasting models.
  • Compressing payloads with Brotli at edge nodes while managing CPU overhead during peak loads.
  • Optimizing QUIC connection migration support for mobile clients switching networks.

Module 7: Observability, Monitoring, and Incident Response

  • Correlating edge logs across PoPs to trace request paths and identify routing anomalies.
  • Setting up distributed tracing for requests traversing multiple CDN layers and third-party integrations.
  • Defining SLOs for cache hit ratio, origin fetch latency, and error rates with automated alerting.
  • Conducting post-incident reviews for cache poisoning or routing misconfigurations to update runbooks.
  • Sampling and exporting flow data (e.g., IPFIX) for forensic analysis during security investigations.
  • Validating monitoring coverage for dark traffic and synthetic transactions in all active regions.

Module 8: Governance, Compliance, and Multi-Tenant Operations

  • Enforcing data residency policies by restricting cache storage and logging to jurisdiction-specific PoPs.
  • Implementing audit logging for configuration changes to CDN settings with role-based access controls.
  • Managing GDPR and CCPA compliance for cached personal data through automated purge workflows.
  • Partitioning infrastructure for enterprise tenants requiring dedicated edge resources and isolated monitoring.
  • Conducting third-party penetration tests on edge configurations and reporting findings to compliance officers.
  • Negotiating SLAs with upstream transit providers to ensure alignment with customer-facing CDN guarantees.
