This curriculum spans the technical and operational complexity of a multi-phase CDN deployment initiative, comparable to the design and integration work performed during an enterprise-scale infrastructure modernization program involving network architecture, security, compliance, and DevOps teams.

Module 1: CDN Architecture and Topology Design

  • Selecting between multi-tier (edge/mid-tier/core) and flat CDN architectures based on content type, geographic reach, and latency requirements.
  • Designing Points of Presence (PoPs) placement using traffic analysis and BGP routing data to optimize regional performance and cost.
  • Integrating private versus public CDN models when handling sensitive or regulated content with strict data residency needs.
  • Implementing DNS-based versus anycast-based request routing and evaluating impact on failover and proximity accuracy.
  • Deciding on edge server hardware specifications (CPU, RAM, SSD caching) based on expected object sizes and request rates.
  • Establishing peering agreements with ISPs to reduce transit costs and improve last-mile delivery performance.

Module 2: Content Caching and Cache Management Strategies

  • Configuring TTLs and cache invalidation policies balancing freshness requirements against origin offload goals.
  • Implementing cache key normalization rules to handle query string variations, cookies, and HTTP headers without cache fragmentation.
  • Deploying proactive cache warming scripts to pre-populate edge caches before traffic surges or content launches.
  • Managing stale-while-revalidate and stale-if-error policies during origin outages or high-latency origin fetches.
  • Using cache hierarchies with parent-child relationships to reduce redundant origin fetches across PoPs.
  • Monitoring hit ratio degradation and diagnosing cache pollution from uncacheable or low-reuse content.

Module 3: Traffic Routing and Load Distribution

  • Configuring health checks and dynamic failover thresholds to reroute traffic during PoP or origin degradation.
  • Implementing geo-proximity routing using RTT measurements versus static IP geolocation databases.
  • Adjusting load balancing algorithms (round-robin, least connections, weighted) based on PoP capacity and utilization.
  • Integrating EDNS-client-subnet in DNS responses to improve routing accuracy for recursive DNS clients.
  • Evaluating Anycast versus Unicast routing for static versus dynamic content delivery use cases.
  • Managing DNS TTLs in routing decisions to balance responsiveness with DNS query load on authoritative servers.

Module 4: Security and DDoS Mitigation at the Edge

  • Deploying WAF rules at the edge to block OWASP Top 10 threats without increasing origin server exposure.
  • Configuring rate limiting policies per client IP, URI, or API endpoint to mitigate credential stuffing and scraping.
  • Implementing TLS 1.3 with session resumption and OCSP stapling to reduce handshake latency at scale.
  • Using IP reputation lists and behavioral analysis to absorb volumetric DDoS attacks before they reach the origin.
  • Managing certificate lifecycle automation across thousands of edge nodes using centralized certificate authorities.
  • Enforcing HTTP/2 and HTTP/3 support selectively based on client compatibility and security audit requirements.

Module 5: Dynamic Content Acceleration and Origin Shielding

  • Deploying dynamic site acceleration (DSA) techniques like TCP optimization and connection pooling for origin offload.
  • Implementing origin shielding with a mid-tier cache to absorb traffic spikes and prevent origin overload.
  • Using edge logic (serverless functions) to personalize content without bypassing the CDN cache entirely.
  • Configuring selective caching of API responses based on HTTP status codes, headers, and response size.
  • Integrating real-user monitoring (RUM) data to identify dynamic content contributing to high origin load.
  • Applying query parameter handling rules to cache personalized or session-based API responses securely.

Module 6: Performance Monitoring and Analytics

  • Instrumenting synthetic monitoring from multiple regions to detect routing or cache failures proactively.
  • Correlating edge logs with origin logs to identify cache bypass patterns and misconfigured headers.
  • Setting up alerting thresholds for cache hit ratio drops, error rate increases, and origin response latency.
  • Using time-series databases to analyze traffic patterns and forecast capacity needs across PoPs.
  • Generating forensic reports from edge logs during security incidents or performance degradation events.
  • Implementing log sampling strategies to balance analytics fidelity with storage and processing costs.
  • Mapping content caching locations to comply with GDPR, CCPA, and other data sovereignty regulations.
  • Configuring purge workflows to meet legal right-to-be-forgotten (RTBF) request SLAs across global PoPs.
  • Enforcing regional content blocking using geo-fencing and license rights verification at the edge.
  • Auditing CDN provider sub-processors for compliance with industry standards like SOC 2 or ISO 27001.
  • Managing logging data retention policies in accordance with jurisdiction-specific legal requirements.
  • Implementing content takedown procedures that align with DMCA or local copyright enforcement frameworks.

Module 8: Integration and Automation in DevOps Workflows

  • Integrating CDN configuration into CI/CD pipelines using infrastructure-as-code (IaC) templates and version control.
  • Automating cache invalidation workflows triggered by content deployment or CMS publishing events.
  • Using API-driven configuration management to enforce consistency across staging and production environments.
  • Implementing canary rollouts for CDN policy changes to minimize impact of misconfigurations.
  • Developing custom dashboards using CDN provider APIs to aggregate performance and security metrics.
  • Orchestrating failover between primary and backup CDNs using health check integrations and DNS automation.
