This curriculum spans the technical, operational, and governance decisions involved in deploying and maintaining a global CDN, comparable in scope to a multi-workshop architecture series co-developed with network engineering, security, and compliance teams across large-scale content delivery initiatives.

Module 1: Defining Content Delivery Objectives and Stakeholder Alignment

  • Select whether to prioritize latency reduction, bandwidth cost containment, or global availability based on business-critical applications and user geography.
  • Determine acceptable time-to-live (TTL) values for cached content in coordination with application owners managing dynamic data dependencies.
  • Negotiate caching policies with legal and compliance teams when handling regulated content such as PII or healthcare data.
  • Map content types (e.g., video, API payloads, static assets) to delivery SLAs based on end-user experience requirements.
  • Decide whether origin shielding is required to protect backend systems from direct public exposure.
  • Establish escalation paths between CDN operations, DevOps, and application support teams for incident resolution.

Module 2: CDN Provider Selection and Multi-Vendor Strategy

  • Evaluate peering agreements and network topology of CDN providers to assess reach and performance in emerging markets.
  • Compare DDoS mitigation capabilities across vendors, including volumetric filtering and behavioral analysis features.
  • Decide whether to adopt a multi-CDN strategy to avoid vendor lock-in and improve regional resilience.
  • Assess API maturity and automation support when integrating CDN configuration into CI/CD pipelines.
  • Negotiate contractual terms around data sovereignty, incident reporting timelines, and audit rights.
  • Validate TLS certificate management workflows, including support for automated renewal and wildcard provisioning.

Module 3: Edge Caching Architecture and Cache Invalidation

  • Configure cache key normalization rules to handle query string variations without creating redundant objects.
  • Implement stale-while-revalidate policies to maintain availability during origin fetch failures.
  • Design cache purge workflows that balance speed with risk, including pre-purge health checks and post-purge validation.
  • Integrate cache tags or surrogate keys into application responses to enable targeted invalidation of related content.
  • Set up cache hit ratio monitoring with thresholds to detect configuration regressions or traffic pattern shifts.
  • Decide when to use forced cache misses (e.g., via cache-busting headers) for A/B testing or canary deployments.

Module 4: Origin Infrastructure and Failover Design

  • Configure origin health checks with appropriate intervals and failure thresholds to prevent premature failover.
  • Implement origin failover logic that considers geographic proximity and load when redirecting traffic.
  • Size origin servers to handle traffic spikes during cache stampedes after mass invalidation events.
  • Deploy read replicas or load-balanced clusters to prevent single points of failure at the origin.
  • Define retry policies for failed origin fetches, including exponential backoff and circuit breaker patterns.
  • Encrypt traffic between edge nodes and origin using mutual TLS when transmitting sensitive payloads.

Module 5: Security, Access Control, and Threat Mitigation

  • Configure signed URLs or tokens for time-limited access to private content such as video streams or documents.
  • Implement bot management rules to distinguish between legitimate crawlers and scraping tools.
  • Deploy WAF rules at the edge to block common OWASP Top 10 vulnerabilities before they reach the origin.
  • Enforce geo-fencing for content restricted by licensing or regulatory requirements.
  • Rotate and audit API keys used for CDN configuration access on a quarterly basis.
  • Log and monitor edge-layer 403 and 401 responses to detect credential leakage or brute force attempts.

Module 6: Performance Monitoring and Real-User Measurement

  • Instrument synthetic monitoring from multiple global locations to detect regional performance degradation.
  • Correlate edge server response times with origin response times to isolate bottlenecks.
  • Deploy real-user monitoring (RUM) to collect actual page load and asset fetch times across devices.
  • Set up alerts for sudden drops in cache hit ratio that may indicate configuration errors or traffic anomalies.
  • Use TCP telemetry from edge nodes to identify connection reuse inefficiencies and TLS handshake delays.
  • Compare Time to First Byte (TTFB) across content types to validate tiered caching strategies.

Module 7: Compliance, Auditing, and Data Governance

  • Configure logging to capture request headers, client IPs, and response codes while complying with data minimization principles.
  • Define log retention periods in alignment with legal hold policies and eDiscovery requirements.
  • Implement audit trails for all configuration changes made to CDN settings, including who made the change and why.
  • Validate that CDN provider certifications (e.g., SOC 2, ISO 27001) meet enterprise compliance obligations.
  • Restrict administrative access to CDN control planes using role-based access control (RBAC) and MFA.
  • Conduct annual reviews of cached content to ensure outdated or decommissioned assets are not served inadvertently.

Module 8: Integration with DevOps and Application Lifecycle

  • Embed CDN cache purge steps into deployment pipelines to ensure stale content is invalidated post-release.
  • Version CDN configuration files alongside application code to enable rollback and change tracking.
  • Use feature flags to progressively enable edge-side includes (ESI) or server-side personalization.
  • Automate certificate provisioning for custom domains using ACME-compatible workflows.
  • Test CDN behavior in staging environments that mirror production TTLs, headers, and routing logic.
  • Enforce configuration drift detection by comparing live CDN settings against source-controlled templates.
