Cloudflare Course

Lesson 1 • Adding Your First Domain

Guides students through adding a domain and updating nameservers at a registrar. Demonstrates how Cloudflare takes control of DNS for a zone.

Lesson 2 • Creating and Configuring an Account

Walks through account registration, plan selection, and dashboard orientation. Students gain hands-on familiarity with the interface used throughout the course.

Lesson 3 • How the Internet Delivers Content

Covers DNS resolution, TCP/IP basics, and HTTP request flow. Establishes the baseline network knowledge required for every subsequent Cloudflare concept.

Lesson 1 • Advanced DNS Features

Introduces DNSSEC, custom nameservers, and DNS-over-HTTPS. Extends basic record management to enterprise-grade security and privacy configurations.

Lesson 2 • DNS Record Types Explained

Covers A, AAAA, CNAME, MX, TXT, and SRV records with practical examples. Provides the vocabulary needed to manage any real-world DNS zone.

Lesson 3 • DNS Propagation and Troubleshooting

Explains caching, TTL expiry, and tools for verifying propagation globally. Students learn to diagnose and resolve common DNS resolution failures.

Lesson 1 • SSL/TLS Fundamentals

Reviews certificate chains, handshake mechanics, and cipher suites. Provides the cryptographic context needed to make informed Cloudflare SSL decisions.

Lesson 2 • Managing Certificates

Covers Universal SSL, Advanced Certificates, and custom certificate uploads. Students provision and renew certificates for any domain configuration.

Lesson 3 • Cloudflare SSL Modes

Compares Off, Flexible, Full, and Full Strict modes with security trade-offs. Students select the appropriate mode based on origin server certificate status.

Lesson 4 • Enforcing HTTPS and HSTS

Configures Always Use HTTPS, HSTS headers, and minimum TLS version. Ensures visitors are never served unencrypted content from a Cloudflare zone.

Lesson 1 • Cache Rules and Cache Levels

Configures cache levels, bypass rules, and custom cache keys using Cache Rules. Students tailor caching behavior per URL pattern, header, or cookie value.

Lesson 2 • How Cloudflare Caching Works

Explains edge caching, cache keys, and the request lifecycle through Cloudflare's network. Establishes the mental model needed to control what gets cached and where.

Lesson 3 • Measuring Cache Performance

Uses Cloudflare Analytics and cache status headers to evaluate hit ratios. Students identify low-performing cache configurations and apply targeted improvements.

Lesson 4 • Cache Purging Strategies

Covers single-file purge, tag-based purge, and purge-all operations via UI and API. Students implement reliable cache invalidation workflows for content updates.

Lesson 1 • Security Analytics and Incident Review

Analyzes WAF events, firewall logs, and security insights in the dashboard. Students use data to refine rules and demonstrate security posture improvements.

Lesson 2 • Writing Custom WAF Rules

Builds custom firewall rules using Cloudflare's expression language to target specific threats. Extends managed rulesets with application-specific logic.

Lesson 3 • DDoS Protection Settings

Configures HTTP DDoS Attack Protection and Network-layer DDoS rulesets. Students adjust sensitivity and override rules to handle legitimate traffic spikes.

Lesson 4 • Understanding Web Threats

Surveys OWASP Top 10 vulnerabilities, DDoS attack types, and bot traffic patterns. Provides the threat context required to configure meaningful security rules.

Lesson 1 • Load Balancing and Failover

Configures Cloudflare Load Balancer with origin pools, health checks, and steering policies. Students build resilient multi-origin architectures with automatic failover.

Lesson 2 • Cloudflare Rules Framework Overview

Maps the relationship between Page Rules, Transform Rules, Redirect Rules, and Configuration Rules. Students understand which rule type to use for each traffic scenario.

Lesson 3 • Redirect Rules and URL Rewrites

Creates static and dynamic redirects and URL rewrites using the Rules engine. Students replace legacy redirect logic with maintainable Cloudflare-native configurations.

Lesson 4 • Transform Rules for Headers

Adds, modifies, and removes HTTP request and response headers via Transform Rules. Enables security headers, A/B test flags, and backend routing signals.

Lesson 1 • Workers KV and Durable Objects

Integrates Workers KV for global key-value storage and Durable Objects for stateful logic. Students persist and share data across edge requests.

Lesson 2 • Advanced Worker Patterns

Implements A/B testing, request authentication, and API gateway patterns in Workers. Students apply real-world architectures that replace origin middleware.

Lesson 3 • Deploying and Monitoring Workers

Publishes Workers to production routes, sets environment variables, and reads logs. Students operate Workers in production with confidence and observability.

Lesson 4 • Writing Your First Worker

Creates a Worker using the Wrangler CLI and the fetch event handler pattern. Students deploy a functional script that intercepts and modifies HTTP requests.

Lesson 1 • Cloudflare Tunnel for Secure Connectivity

Deploys cloudflared to expose private services without opening inbound firewall ports. Students connect an origin to Cloudflare's network through an outbound-only tunnel.

Lesson 2 • Cloudflare Access for Applications

Protects internal applications with identity provider integration and policy rules. Students publish an app through Access and enforce multi-factor authentication.

Lesson 3 • Cloudflare Gateway and DNS Filtering

Configures Gateway DNS and HTTP policies to block threats and enforce acceptable use. Students protect outbound traffic from devices enrolled in the Zero Trust organization.

Lesson 4 • Monitoring and Auditing Zero Trust Events

Reviews Access logs, Gateway activity logs, and risk score signals in the dashboard. Students build audit workflows that satisfy compliance and incident response needs.
