This curriculum spans the technical and operational complexity of a multi-workshop program for designing, securing, and operating global content delivery architectures, comparable to the planning and execution cycles seen in large-scale internal CDN migration or multi-vendor edge platform integration projects.

Module 1: CDN Infrastructure Selection and Sizing

  • Selecting between multi-CDN and single-CDN architectures based on geographic coverage requirements and third-party dependency risk tolerance.
  • Calculating origin server bandwidth requirements when offloading traffic through edge caching, factoring in cache hit ratios and flash crowd scenarios.
  • Evaluating POP density versus latency SLAs for real-time content delivery in emerging markets with limited infrastructure.
  • Determining TTL values for dynamic content based on update frequency and consistency requirements across distributed edge nodes.
  • Assessing the impact of HTTP/2 and HTTP/3 support on connection reuse and edge-to-origin traffic patterns.
  • Integrating real-user monitoring (RUM) data into infrastructure planning to validate performance assumptions across devices and networks.

Module 2: Edge Caching Strategy and Cache Invalidation

  • Designing cache key structures to handle query string variations, cookies, and device-specific content without cache fragmentation.
  • Implementing stale-while-revalidate policies for high-traffic pages to maintain availability during origin outages.
  • Configuring selective caching rules for personalized content using edge logic to strip or bypass user-specific headers.
  • Deploying cache tags or surrogate keys to enable bulk invalidation of related content after CMS updates.
  • Managing purge queue backlogs during mass content deployments to prevent origin overload from simultaneous revalidation requests.
  • Using conditional requests (ETag, Last-Modified) in origin responses to minimize bandwidth usage during revalidation.

Module 3: Security Integration at the Edge

  • Positioning WAF rules at the edge to block volumetric attacks before they reach the origin, balancing false positive rates with protection coverage.
  • Configuring TLS termination at the edge with proper certificate management workflows for automated renewal and domain coverage.
  • Enforcing HTTP Strict Transport Security (HSTS) via edge headers while managing browser preload list implications.
  • Implementing bot mitigation strategies using rate limiting, fingerprinting, and challenge mechanisms at the CDN layer.
  • Restricting direct access to origin servers using IP allowlists and authentication tokens enforced at the CDN.
  • Handling DDoS mitigation handoffs between CDN and cloud provider DDoS protection services during large-scale attacks.

Module 4: Performance Optimization and Request Routing

  • Configuring DNS-based load balancing with health checks to route users to the nearest healthy POP based on latency and availability.
  • Implementing Anycast routing for edge endpoints to improve failover and reduce latency in global deployments.
  • Optimizing image delivery using client hints and edge-side image transformation services to reduce payload size.
  • Deploying edge-side includes (ESI) to assemble composite pages from cached fragments with varying TTLs.
  • Using request coalescing to prevent cache stampedes when popular content expires simultaneously.
  • Integrating Real User Monitoring (RUM) with synthetic monitoring to identify regional performance degradation.

Module 5: Origin Shield and Back-End Architecture

  • Deploying origin shields to reduce load on origin servers during traffic spikes and cache misses.
  • Configuring origin keep-alive connections and connection pool sizing to minimize TLS handshake overhead.
  • Implementing circuit breaker patterns at the edge to prevent cascading failures during origin degradation.
  • Using origin failover configurations with secondary backup origins for high-availability content delivery.
  • Setting up origin error caching policies to serve stale content during transient backend failures.
  • Monitoring origin response times and error rates to trigger automated configuration adjustments or alerts.

Module 6: Observability and Monitoring at Scale

  • Instrumenting CDN logs to capture cache hit/miss status, response time, and geographic metadata for analysis.
  • Aggregating and parsing CDN access logs in real time to detect traffic anomalies and configuration errors.
  • Correlating edge metrics with origin metrics to identify bottlenecks in the delivery chain.
  • Setting up alerting thresholds for cache hit ratio drops, error rate increases, and origin latency spikes.
  • Using distributed tracing to follow a request from user to edge to origin in complex delivery paths.
  • Generating synthetic transactions to validate caching behavior and security policies across regions.
  • Mapping content delivery paths to ensure user data does not traverse restricted jurisdictions in compliance with data sovereignty laws.
  • Configuring logging and data retention policies at the edge to meet GDPR, CCPA, and other privacy regulations.
  • Implementing geo-blocking for legally restricted content based on IP geolocation with fallback verification.
  • Managing cookie consent enforcement at the edge for personalized content in regulated regions.
  • Auditing CDN provider certifications (SOC 2, ISO 27001) and contractual data processing terms for compliance alignment.
  • Handling lawful interception and takedown requests through documented CDN provider processes and internal coordination.

Module 8: Multi-Tenant and Hybrid CDN Environments

  • Partitioning CDN configurations for multiple business units or brands to enforce isolation and billing accountability.
  • Integrating private CDN nodes into hybrid architectures for internal applications with sensitive data requirements.
  • Orchestrating traffic failover between public CDN providers using DNS or GSLB during regional outages.
  • Standardizing configuration templates across CDN vendors to reduce operational complexity in multi-CDN setups.
  • Managing certificate deployment and renewal across multiple CDN platforms with centralized tooling.
  • Monitoring cross-CDN performance and cost metrics to dynamically adjust traffic steering policies.
